1. Understanding Heart Palpitations: The Sensation of a Skipped Beat
Heart palpitations can manifest in various ways, including the feeling that your heart is skipping a beat. This sensation can be alarming, but it’s essential to understand what’s happening in your body. According to the National Institutes of Health (NIH), palpitations are often described as a racing, fluttering, or pounding heartbeat. This section will explore the mechanics of a skipped heartbeat and what it signifies.

1.1 The Regular Rhythm of Your Heart
Your heart typically beats in a consistent rhythm, which you usually don’t notice. This rhythm is controlled by electrical signals that coordinate the contractions of your heart chambers. As Andrew Zadeh, MD, a cardiologist at Keck Medicine of USC, explains, each heartbeat sends a pulse through your body.
1.2 What Happens When Your Heart Skips a Beat?
The sensation of a skipped beat often occurs when there’s an interruption in your heart’s regular rhythm. This interruption can be caused by an extra beat, known as a premature contraction. Dr. Zadeh notes that when this happens, the force of the blood being pumped from your heart isn’t timed correctly, resulting in a weaker pulse. This weaker pulse can feel like your heart is pausing or skipping a beat. This phenomenon involves understanding cardiac arrhythmia and premature ventricular contractions.
1.3 The Science Behind the Sensation
“When patients say they feel their heart ‘skipping a beat,’ it is usually tied to a single premature beat that fails to produce an extra pulse,” Dr. Zadeh explains. “The ‘skip’ is the ‘pulseless’ time it takes for the next beat or pulse to come in.” In essence, your heart’s rhythm is temporarily disrupted, making you aware of its activity.
2. Common Causes of the Feeling of a Skipped Heartbeat
Many factors can contribute to the sensation of a skipped heartbeat. While some causes are benign, others may indicate underlying health issues. It’s crucial to identify potential triggers and seek medical advice if you have concerns.
2.1 Anxiety and Stress: The Mind-Heart Connection
Anxiety and stress are significant contributors to heart palpitations. When you’re under stress, your body releases hormones like adrenaline, which can increase your heart rate and cause irregular heartbeats. Mental health issues, such as anxiety disorders, can also trigger palpitations. In a vicious cycle, experiencing palpitations can further exacerbate anxiety.
2.1.1 Managing Stress and Anxiety
You can take several steps to reduce stress and anxiety and alleviate the feeling of a skipped heartbeat. These include:
- Breathing exercises: Deep, slow breathing can help calm your nervous system.
- Relaxation techniques: Yoga, meditation, and tai chi can reduce stress and promote relaxation.
- Mindfulness: Focusing on the present moment can help reduce anxiety.
- Regular exercise: Physical activity can help release tension and improve mood.
2.2 Lifestyle Factors: Caffeine, Alcohol, Nicotine, and Medications
What you consume can significantly impact your heart rhythm. Certain substances can act as stimulants, leading to palpitations.
2.2.1 Caffeine
Caffeine is a well-known stimulant that can increase heart rate and trigger palpitations in sensitive individuals. The American Heart Association (AHA) suggests that moderate caffeine consumption is generally safe, but excessive intake can lead to adverse effects.
2.2.2 Alcohol
Alcohol can also cause heart palpitations, particularly in individuals prone to arrhythmias. The effects of alcohol on heart rhythm can vary depending on the individual and the amount consumed.
2.2.3 Nicotine
Nicotine, found in tobacco products, is another stimulant that can increase heart rate and blood pressure, leading to palpitations. Smoking also damages blood vessels and increases the risk of heart disease.
2.2.4 Medications
Several medications, both over-the-counter and prescription, can cause heart palpitations as a side effect. These include:
- Decongestants: These medications can raise blood pressure and heart rate.
- Diet pills: Some diet pills contain stimulants that can trigger palpitations.
- Asthma medications: Certain asthma medications can increase heart rate.
- Illegal drugs: Drugs like cocaine can cause severe heart arrhythmias and palpitations.
Identifying and avoiding or reducing these lifestyle factors can help minimize the frequency of palpitations.
2.3 Atrial Fibrillation (A-Fib): An Irregular Heartbeat
Atrial fibrillation (A-fib) is a common type of arrhythmia characterized by an irregular and often rapid heart rate. In A-fib, the upper chambers of the heart (atria) beat chaotically and out of sync with the lower chambers (ventricles). According to the Centers for Disease Control and Prevention (CDC), A-fib increases the risk of stroke, heart failure, and other complications.
2.3.1 Symptoms of A-Fib
Besides the sensation of a skipped heartbeat, other symptoms of A-fib include:
- Lightheadedness
- Fatigue
- Shortness of breath
- Chest pain
2.3.2 Risk Factors for A-Fib
Older adults and people with high blood pressure, obesity, diabetes, or other health problems are more likely to develop A-fib. It’s essential to manage these risk factors and seek medical treatment for A-fib to reduce the risk of complications.
2.4 Heart Disease: Structural and Functional Issues
Various forms of heart disease can cause heart palpitations. These include problems with the heart’s valves, muscles, or arteries.
2.4.1 Mitral Valve Prolapse
Mitral valve prolapse (MVP) is a condition in which the mitral valve, which separates the upper and lower chambers on the left side of the heart, doesn’t close properly. MVP is the most common structural heart problem to cause palpitations.
2.4.2 Cardiomyopathy
Cardiomyopathy is a disease of the heart muscle that can cause the heart to enlarge, thicken, or become rigid. This can lead to arrhythmias and palpitations.
2.4.3 Coronary Heart Disease
Coronary heart disease (CHD) involves the narrowing of the arteries that supply blood to the heart. This can lead to chest pain (angina), shortness of breath, and arrhythmias, including palpitations.
Heart disease can be evaluated through tests such as electrocardiograms, echocardiograms, and stress tests.
2.5 Overactive Thyroid: The Role of Hormones
An overactive thyroid, also known as hyperthyroidism, occurs when the thyroid gland produces too much thyroid hormone. This hormone regulates metabolism, and excess amounts can increase heart rate and cause palpitations. The American Thyroid Association notes that hyperthyroidism is relatively easy to diagnose with blood tests.
2.5.1 Symptoms of Hyperthyroidism
Other symptoms of hyperthyroidism include:
- Weight loss
- Increased appetite
- Anxiety
- Tremors
- Sweating
- Heat intolerance
Medications are available to treat hyperthyroidism and alleviate symptoms like palpitations.
3. Diagnostic Tests for Heart Palpitations
When you experience heart palpitations, your doctor may recommend several diagnostic tests to determine the cause. These tests help assess your heart’s structure, function, and electrical activity.
3.1 Electrocardiogram (ECG or EKG)
An electrocardiogram (ECG or EKG) is a non-invasive test that records the electrical activity of your heart. It can detect arrhythmias, heart muscle damage, and other abnormalities.
3.2 Holter Monitor
A Holter monitor is a portable ECG device that you wear for 24 to 48 hours. It continuously records your heart’s electrical activity, allowing your doctor to identify irregular heartbeats that may not be detected during a standard ECG.
3.3 Event Recorder
An event recorder is another type of portable ECG device that you wear for a longer period, typically weeks or months. Unlike a Holter monitor, an event recorder only records when you experience symptoms.
3.4 Echocardiogram
An echocardiogram is an ultrasound of the heart. It provides detailed images of your heart’s structure and function, allowing your doctor to assess the heart valves, chambers, and blood flow.
3.5 Stress Test
A stress test involves monitoring your heart’s electrical activity while you exercise on a treadmill or stationary bike. It can help identify coronary artery disease and other heart problems that may not be apparent at rest.
3.6 Blood Tests
Blood tests can help identify underlying conditions that may be causing heart palpitations, such as thyroid disorders or electrolyte imbalances.
4. When to Seek Medical Attention for Heart Palpitations
While most heart palpitations are not serious, it’s essential to know when to seek medical attention. If you experience any of the following symptoms along with palpitations, consult a doctor promptly:
- Chest pain or discomfort
- Shortness of breath
- Dizziness or lightheadedness
- Fainting or near-fainting
