Heart Rate Variability (HRV) is a Key Indicator of Cardiovascular Health

The State of our Hearts Tell us Much About Ourselves

HRV is a key indicator of cardiovascular health, reflecting the heart’s ability to adapt to physiological demands. A lower HRV suggests poorer heart rate regulation and reduced resilience to both environmental (e.g., stress, fear) and physiological stressors (e.g., systemic inflammation, a hallmark of COVID-19).

The science of heart rate variability (HRV) allows us to explore the incredible and wonderful world of the heart. HRV is a physiological marker of how we experience and regulate our emotions. HRV is relatively easy to measure. Rather than calculating the number of beats per minute, we measure the time that elapses between one heartbeat and the next one.

HRV is the heart’s authentic voice, so HRV must lead the next revolution in cardiology. In the heart of every human being is a rhythm. Not just the beat of survival—but the song of how we live. Cardiology has treated the heart like a machine for too long—measuring its pressure, blockages, and ejection fraction. But the heart is not only a mechanical pump. It is a resonant field, a relational organ, and a spiritual barometer of human integrity.

HRV measures the variation in time between your heartbeats. But beneath that technical definition lies something profound: HRV is your body’s truth signal. It reflects your adaptability, emotional openness, and capacity to meet the moment without resistance.

  • High HRV = flexibility, coherence, and aliveness.
  • Low HRV = rigidity, contraction, dissonance.

HRV is the body’s way of showing us whether we are coherent with our being. It is not just about rest and recovery—it is about resonance and how honest we are willing to be. A flexible heart is a sincere heart. A high HRV often reflects a state of inner alignment, openness, vulnerability, and presence. So yes, the state of our hearts does tell us much about ourselves. And sometimes, it tells us everything.

A high HRV doesn’t just mean you’re relaxed. It means you’re real. It means your nervous system isn’t caught in a performance. It means you are, at this moment, undefended.

Ever wondered how stressed you are? Heart Rate Variability (HRV) is a practical way to quantify your stress and health objectively. While some amount of stress can be good, being in a constant, long-term state of stress can be very bad for our bodies and minds. HRV helps you objectively understand the state of your body and what factors trigger a stress response in you.

The Story of David and the Listening Heart

David was quiet but not the kind that didn’t speak—he just listened more than he talked. And not just with his ears. He listened with his heart. Before the world stirred, David clipped a small black sensor to his ear every morning. It was his ritual—tracking his HRV. Not because he was obsessed with numbers, but because it told him something more profound than metrics—the truth about his inner state.

Some mornings, his HRV was high—his heart moving like a jazz band: full of flexibility, rhythm, and presence. On those days, he felt spacious and alive, able to meet the world with an open chest and an unguarded soul.

Other mornings, it was low—tight, rigid, predictable. And sure enough, he’d find himself tense, irritable, or withdrawn. His body was giving him a whisper of something before his mind could catch up. It wasn’t just stress or sleep. It was everything: the argument he’d had with his daughter two days ago and hadn’t apologized for. The dream he kept postponing. The unspoken grief he wore like armor. His heart told the story before his mouth did.

One morning, after a sleepless night and an HRV score scraping the bottom, he didn’t meditate or exercise. He just picked up the phone and called his brother. The one he hadn’t spoken to in seven years. The one whose name made his chest tighten. They cried. They laughed. They didn’t fix everything, but they cracked the shell. The following day, his HRV was the highest it had ever been. David smiled. His heart had listened to the pain. And in return, it had softened.

Introducing The Power Of Mindfulness!

If you answer YES to any of the below, you need this…

You’re currently feel stressed out
You deal with fear of things like public speaking…
You can’t seem to turn your mind off when during your day…
You’ve resorted to medication to help with stress, fear, and anxiety
You want to have more success in your life
You want to be the best you can be!

Emotional Truth as Medicine

Here’s what science rarely says out loud: The truth heals. Not abstract truth, but felt truth. Truth that makes the chest ache and the tears come. The tears of the melting heart are healing. The Heart is the organ of truth. One cannot live a lie and be in the heart.

An apology raises HRV.
Forgiveness raises HRV.
Crying, real crying—not the performative kind—raises HRV.
So does awe.
So does wonder.
So does love, when it’s not confused with possession or fear of loss.

We’ve been trained to chase health as a physical outcome. But health begins in honesty. HRV measures the integrity of your nervous system. But underneath that, it measures the alignment between your being and living.

HRV as the Soul’s Stethoscope

A high HRV doesn’t mean you’re an athlete. It means your system is available for love. Every sigh you release, every truth you speak, and every emotion you feel tune the heart’s rhythm back into the living orchestra of the parasympathetic nervous system.

HRV as the Core Metric of Natural Cardiology

Let this be said clearly:

Any cardiology that ignores HRV is incomplete.
Any medicine that ignores emotion, truth, and coherence is blind.
And any health system that doesn’t teach people to feel, breathe, and listen is not healing—it’s managing dysfunction.

HRV should be:

  • A daily vital sign.
  • A guide for emotional literacy.
  • A tool for spiritual feedback.
  • A foundation of proper prevention.

Not just for elite athletes or biohackers. For everyone who has a heart—and wants to hear it speak.

Dr. Bessel van der Kolk says, “The heart, gut and brain communicate intimately via the vagus nerve, the critical nerve involved in expressing and managing emotions in humans. We experience emotions in our bodies, not in our heads. Emotions are first a physical state and only secondarily interpreted as a perception in the brain. By learning literally how to control our heart, we learn how to gain mastery of our emotional brain and vice versa. We can change the state of our brains by what we do with our bodies. The way we move, the way we breathe, and the way we interact with other people physically. Important that we experience emotions in our body and not in our head.”

The American Institute of Stress has reported that up to 90% of doctor’s visits are stress-related. A patient’s HRV gives us a full readout regarding health, medical diagnosis, and treatment pathways that will bring a person back to harmony and health. The bottom line is that the heart knows what is happening in the body. HRV can provide information to users about situations where their stress or anxiety levels are higher than usual.

Heart rate variability, or heart rhythms, is the most dynamic and reflective indicator of one’s emotional states, current stress, and cognitive processes. An optimal, flexible level of HRV reflects healthy function; too little variation indicates chronic stress and pathology. The HRV of any individual is directly dependent on vagus nerve tone and function.

Health Professionals and Patients Can Tune Directly into the Heart

The first image above shows me on a highly stressed-out day. The photo shows very little HRV, meaning I was practically flatlining regarding HRV and stress. The flatter our heartbeats are, the more stressed we are and the closer we are to death.

The image directly above shows a vastly increased HRV, and it was wonderful, for a change, to see my heart changing up and down nicely as I did yogic breathing during the test. This showed me that it is possible to get a direct hold of how my heart is beating and a direct hold on the stress I am putting my body through.

Meditation, slow breathing techniques, and positive social relationships help the Vagus nerve. Deep and slow breathing stimulates the vagus nerve, especially yogic alternative nostril breathing, and I was doing three-part yogic breathing to increase my HRV.

Breathing in and out with resistance will also stimulate your Vagus nerve; the Frolov breathing retraining device is suitable for practicing that. Mild exercise stimulates gut flow. This is mediated by the vagus nerve, which means that exercise stimulates the vagus nerve. The heart is the organ that loves to exercise. Singing increases HRV, as does laughter.

Statins are still very cheap and highly effective cholesterol-lowering drugs, they like to say, but high-risk heart patients may have an even better option, a new evidence review says. Combining statins with another drug, ezetimibe, significantly reduces the risk of death in patients with clogged arteries, according to findings published Sunday in Mayo Clinic Proceedings.

Rheumatism

Rheumatism is a broad and somewhat outdated term that has been historically used to describe various conditions characterized by pain and inflammation in the muscles, joints, and connective tissues. However, in modern medicine, the term “rheumatism” is no longer used as a specific diagnosis because it doesn’t refer to a single, well-defined medical condition. Instead, healthcare professionals use more specific and accurate terminology to describe the various disorders that can affect the musculoskeletal system.

Statins are still very cheap and highly effective cholesterol-lowering drugs, they like to say, but high-risk heart patients may have an even better option, a new evidence review says. Combining statins with another drug, ezetimibe, significantly reduces the risk of death in patients with clogged arteries, according to findings published Sunday in Mayo Clinic Proceedings.

What they do not say is that the chemical combo increases the risk of adverse drug interactions, and thus, side effects are probably multiplied. But what they do say is that this combination therapy would prevent more than 330,000 deaths a year worldwide among patients who have already suffered a heart attack, including almost 50,000 deaths in the U.S. alone, researchers said.

“This study confirms that combined cholesterol lowering therapy should be considered immediately and should be the gold standard for treatment of very high-risk patients after an acute cardiovascular event,” senior researcher Dr. Peter Toth, a professor of clinical family and community medicine at the University of Illinois, said in a news release.

I do not believe a word of it.

Not when the so-called “evidence” is brought to us by pharmaceutical insiders, echoed by compromised journals, and spoon-fed to the public through press releases designed to scare and sell. The idea that combining statins with another drug like ezetimibe — both known to cause adverse effects — will now become the “gold standard” for saving lives is not only scientifically dishonest, it’s medically reckless.

Let’s be clear: Statins do not treat the root cause of heart disease. They merely manipulate a number — cholesterol — that’s been scapegoated for decades. As I’ve written before, cholesterol is not the enemy. It is essential, even protective, especially during physiological stress or inflammation. The real villain isn’t cholesterol — it’s inflammation. It’s oxidative stress. It’s magnesium deficiency. It’s acidic tissue environments.

What’s worse, this “gold standard” of dual-drug therapy does nothing to address the cause of cardiovascular disease—it merely numbs the metrics while the fire burns on beneath the surface. Statins and ezetimibe do not touch the deeper pathology. They do not reduce arterial stiffness, restore endothelial function, or regenerate heart tissue. They suppress, silence, mask, and damage.

This system is built on lies so deeply embedded in medical culture that even “confessions of a cardiologist,” as I once highlighted, are not enough to turn the tide. They know it’s inflammation. They know it’s about the terrain. Yet they keep prescribing drugs that damage the liver, drain CoQ10, suppress cognition, and provoke muscular degeneration.

They are crazy because they dare to call this progress.

Meanwhile, in the natural world, solutions abound — and they don’t require prescriptions. They require understanding. Bicarbonate therapy, magnesium repletion, vitamin D restoration, high-dose omega-3s, infrared therapy, and breathing techniques that regulate CO₂ and oxygen balance. These are the actual “gold standard” therapies. And unlike statins, they don’t cause side effects — they create side benefits.

If we are going to stop heart disease — truly stop it — we must abandon this cholesterol-lowering myth once and for all. The body isn’t betraying us. It’s doing its best under toxic, nutrient-depleted, pharmaceutically hijacked conditions. The betrayal is not in your arteries. It’s in the medical-industrial complex. It’s in the pills sold as salvation while the cause is ignored.

Medical truth is oxygen for heart and vascular patients. Hearts are worth saving; that is what modern cardiology is supposed to be all about. However, the death rate from cardiovascular disease is off the charts, bringing sudden death or cerebral degeneration to uncounted millions.

In my work on cardiovascular healing, I’ve long emphasized that cholesterol is not the cause. It’s a response. It’s like the firefighter at the fire scene — and the statin industry is busy shooting the firefighter while the flames rage on. What’s burning the house down is inflammation, oxidative damage, calcium dysregulation, and — at the very root — magnesium deficiency.

Magnesium is the guardian mineral of the heart. It calms the nervous system, prevents arterial calcification, improves mitochondrial function, and facilitates over 600 enzymatic processes. But it doesn’t work alone. One of our time’s most exciting medical combinations is emerging not from billion-dollar pharmaceutical pipelines but from intelligent synergy: Cyclodextrin and Magnesium. This pair is what I now call the Batman and Robin of cardiovascular regeneration.

Cyclodextrins—unique ring-shaped molecules—have the uncanny ability to encapsulate and extract cholesterol crystals, toxins, and inflammatory debris from arterial walls without harming the structural integrity of the tissues. But their true superpower? Creating space—making room for healing. And when that space is opened, magnesium rushes in like a master mechanic, recharging the cells, calming the terrain, and rebooting life from the inside out.

Unlike statins, which paralyze a protective function, Batman and Robin mobilize your body’s true intelligence. They don’t suppress symptoms — they restore coherence. They don’t generate side effects — they generate life. Imagine if we shifted the standard of care from suppression to regeneration. From cholesterol obsession to inflammation resolution.

That is the revolution we are introducing with our new book on natural cardiovascular medicine:

Coming Soon Free to My Paid Substack Readers

So yes, go ahead and stack your statins with ezetimibe — if your goal is to keep dying slowly. But if you want to reverse heart disease, reclaim your energy, and heal your heart from the inside out, look elsewhere.

Look to magnesium and bicarbonate, cyclodextrins and CO₂, oxygen, hydrogen, and other things that make up a potent protocol. Batman and Robin have arrived. And they don’t wear lab coats. They restore flow. They clear space. They turn the lights back on. And that, not another cholesterol-lowering pill, is how you save a heart.
