What Causes a Low Heart Rate?

Low Heart Rate

The heart is not just the center of our emotional life; it’s also the hardworking muscle that dictates the pace and rhythm of our physical existence. While an elevated heart rate often garners attention, a consistently low heart rate below 60 beats per minute, termed bradycardia, is equally significant and may hint at underlying health issues.

The heart’s natural cadence changes to meet the body’s demands. But when that rhythm continuously slows, it beckons a closer examination. Many factors, from daily lifestyle choices to more subtle environmental exposures, can influence our heart’s pace. Dive with us into nine pivotal causes behind a reduced heart rate and their implications for overall health.

1. Advanced Age

It’s no secret: As the years roll by, our bodies undergo countless transformations. One of the subtler shifts might be nestled within our chest—our heart rate. 

Much like how skin loses elasticity or eyesight blurs, the heart’s electrical system can change with age, leading to a natural decrease in heart rate. Recognizing this physiological evolution can be the first step in discerning if there’s an actual concern.

2. Athletic Conditioning 

Paradoxically, being in exceptional physical shape can also be a reason for a lower heart rate. Athletes, especially those in endurance sports, often showcase heart rates that would raise eyebrows in the average person. Why? Their finely tuned and efficient hearts can pump more blood with fewer beats. It’s like the relaxed pace of a seasoned marathoner compared to a sprinter’s frantic dash.

3. Medications 

In the age of pharmaceutical breakthroughs, many have found solace in pills and prescriptions. Yet, these wonder drugs often come with strings attached. 

Beta-blockers, commonly prescribed for high blood pressure or heart conditions, can intentionally slow the heart rate. Others, like certain calcium channel blockers and antiarrhythmics, can have a similar effect. In fact, these drugs sometimes send the heart rate plummeting to dangerously low rates. 

Individuals dealing with slow heart rates should consider any pharmaceutical medications they may be taking, including antidepressants, narcotics, and cardiac drugs. 

4. Thyroid  Abnormality

One often overlooked factor contributing to a low heart rate is the condition of our thyroid gland. The thyroid is a butterfly-shaped gland in our neck that releases hormones. These hormones directly influence many bodily functions. An underperforming thyroid, or hypothyroidism, slows various bodily functions, including the heart. 

While conventional thyroid tests are a starting point, they don’t always paint the complete picture. These standard tests often only measure a few thyroid markers, potentially missing subtle imbalances that could hint at the beginning stages of dysfunction.

A comprehensive thyroid panel is a more insightful approach for those concerned about their thyroid health and its potential impact on heart rate. Unlike standard screenings, these panels delve deeper, examining a range of markers to provide a holistic view of thyroid function. NHD offers such testing through our advanced cardiac panel, ensuring individuals receive the most thorough assessment. 

5. Dietary and Lifestyle Choices

Our ancestors relied on a rhythmic daily life, rising with the sun and consuming whole, nutrient-dense foods. Today, our habits have drastically changed, sometimes at the heart’s expense. Consuming processed foods high in unhealthy fats and sugars can overburden the heart. While an initial response might be an increased heart rate, chronic exposure can exhaust the heart, decreasing the rate.

Moreover, excessive alcohol consumption, while initially raising the heart rate, can depress the central nervous system over time, slowing down the heart. A sedentary lifestyle further compounds this, with the heart lacking regular stimulation to maintain an optimal beat.

The heart, in its wisdom, responds to our choices. Prioritizing nutrient-rich and organic diets, moderate exercise, and quality sleep can be the difference between a sluggish and a lively heart rhythm.

6. Imbalance in the Nervous System

The autonomic nervous system (ANS) governs our body’s instinctual responses. It is split into two parts: the sympathetic, which kicks in during stress (“fight or flight”), and the parasympathetic, which helps us relax (“rest and digest”). 

These two systems should work harmoniously, helping our body react appropriately to its surroundings. However, when this balance is disrupted, issues arise. 

Chronic stress or lingering trauma can cause the parasympathetic system to over-engage. Initially, this will present as a fast heart rate, or tachycardia. However, over time, the heart may get tired and begin to slow its pace. 

The heart is, in essence, a reflection of this balance. The heart responds in kind when the nervous system’s communication lines falter. Biofeedback, deep breathing exercises, and chiropractic care can be beneficial in restoring this critical equilibrium.

7. Mold Exposure 

We are surrounded by a silent army of toxins, from the air we breathe to some homes’ walls. Among these threats is mold, an unassuming yet potent factor in heart health.

Mold thrives in damp, poorly ventilated areas, releasing spores and mycotoxins. While respiratory issues are a well-documented response to mold exposure, there’s growing concern about its impact on the heart. Specifically, certain mycotoxins may compromise mitochondrial function – the cellular powerhouses vital for energy production, including the heart’s regular rhythm.

Moreover, exposure to mycotoxins has been linked to inflammation, oxidative stress, and even electrolyte imbalances, all of which can alter heart function and lead to a slowed heartbeat.

Combating mold is a multi-pronged approach: thorough mold testing and eradication in one’s living environment, coupled with detoxification strategies under a healthcare professional’s guidance. NHD is highly skilled at helping individuals heal from mold-related health concerns. 

8. Environmental Toxin Exposure

While mold is a significant environmental toxin, it isn’t the only one. Everyday exposures, from vehicular emissions to chemical-laden products, can accumulate in our systems. Prolonged exposure can disturb our body’s natural rhythms, impacting hormonal balance, cellular functions, and, yes, the heart’s pacing.

Heavy metals are particularly concerning. Even at low levels, they can interfere with heart cell function and the electrical signals directing each heartbeat. Similarly, persistent organic pollutants (POPs) – residues from pesticides, industrial chemicals, and more – can accumulate in our bodies, potentially impacting cardiac health.

The message is clear: In an age where invisible threats linger, proactive measures like regular detoxification, choosing organic products, drinking pure water, and ensuring clean air become not just preferable but essential.

Next Steps 

A low heart rate, while sometimes indicative of optimal athletic conditioning, can also indicate that the body is signaling an imbalance or potential concern. Multiple factors come into play, from the foods we consume to the environment we inhabit.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
