1. What Does It Mean When My Heart Skips a Beat?
A skipped heartbeat, often referred to as a heart palpitation, feels like your heart has paused briefly or added an extra beat. According to Dr. Andrew Zadeh, a cardiologist at Keck Medicine of USC, this sensation usually signifies a disruption in your regular heart rhythm. While most occurrences are harmless and related to lifestyle factors, understanding the potential causes and seeking appropriate evaluation is essential. These irregular heart rhythms can be disconcerting, and understanding their origins is the first step toward effective management.
Heart palpitations can manifest in various ways, including a fluttering sensation, a pounding feeling, or the sensation of your heart briefly stopping. These experiences can be triggered by a range of factors, from emotional states like excitement or anxiety to physical exertion. While occasional palpitations are generally not a cause for concern, frequent or persistent occurrences warrant medical attention to rule out underlying heart conditions.

2. What is the Science Behind a Skipped Heartbeat?
To understand the sensation of a skipped heartbeat, it’s helpful to know the basics of how your heart functions. Each heartbeat generates a pulse, which is the force exerted by the increase in pressure within your arteries as blood is pumped out of the heart. As explained by Dr. Zadeh, when an extra beat disrupts the regular heart rhythm, the force of blood being pumped may not be as strong or properly timed.
This irregular beat can result in a reduced pressure increase, leading to a weaker pulse or sometimes no noticeable pulse at all. The “skipped” feeling is often due to this pulseless time, which lasts until the next regular beat occurs. The irregularity can be caused by premature ventricular contractions (PVCs) or premature atrial contractions (PACs), which are early beats that disrupt the normal rhythm.
According to a study published in the Journal of the American Heart Association, occasional PVCs and PACs are common and usually benign. However, frequent or symptomatic PVCs and PACs may indicate an underlying cardiac issue that requires further investigation. Factors such as electrolyte imbalances, caffeine intake, and stress can also contribute to these irregular heartbeats. Understanding these mechanisms can help you better interpret the sensations you’re experiencing and know when to seek professional medical advice.
3. What are the 5 Common Causes of a Skipped Heartbeat?
3.1. Anxiety and Stress
Anxiety and stress are significant contributors to heart palpitations. When you’re under stress or feeling anxious, your body releases stress hormones like adrenaline, which can speed up your heart rate and cause irregular heartbeats. Mental health conditions can significantly impact your heart rhythm, creating a feedback loop where palpitations increase stress levels. Managing stress and anxiety is crucial for reducing the frequency and intensity of these palpitations.
Incorporating relaxation techniques into your daily routine can help mitigate the effects of stress on your heart. Breathing exercises, such as deep, diaphragmatic breathing, can calm the nervous system and slow down your heart rate. Other effective strategies include yoga, meditation, and tai chi, which promote relaxation and reduce overall stress levels. According to the Anxiety and Depression Association of America (ADAA), regular practice of these techniques can lead to significant improvements in both mental and physical health.
By proactively managing your stress and anxiety, you can reduce the occurrence of heart palpitations and improve your overall well-being. If you find that your anxiety is overwhelming or difficult to manage on your own, consider seeking professional help from a therapist or counselor.
3.2. Caffeine, Alcohol, Nicotine and Medications
Substances like caffeine, alcohol, and nicotine can significantly impact your heart rhythm and trigger palpitations. These substances act as stimulants, increasing heart rate and blood pressure, which can lead to irregular heartbeats. Certain medications, including over-the-counter decongestants, diet pills, and prescription drugs like asthma medications, can also contribute to palpitations.
A study in the Journal of the American College of Cardiology found that high caffeine intake can increase the risk of atrial fibrillation, a common cause of palpitations. Similarly, excessive alcohol consumption has been linked to irregular heartbeats, particularly during “holiday heart syndrome,” where atrial fibrillation occurs after heavy drinking. Nicotine from cigarettes and other tobacco products can also stimulate the heart and cause palpitations.
Identifying and reducing your intake of these substances is essential for managing heart palpitations. Start by monitoring your caffeine, alcohol, and nicotine consumption to see if there’s a correlation between your intake and the occurrence of palpitations. Gradually reduce your intake to avoid withdrawal symptoms.
Consult your healthcare provider about any medications you’re taking to see if they could be contributing to your palpitations. They may be able to recommend alternative medications or adjust your dosage. By making conscious choices about what you put into your body, you can significantly reduce the frequency and severity of heart palpitations.
3.3. Atrial Fibrillation (A-Fib)
Atrial fibrillation (A-Fib) is a common arrhythmia characterized by irregular and rapid heartbeats. In A-Fib, the upper chambers of the heart (atria) beat chaotically and out of sync with the lower chambers (ventricles). This uncoordinated rhythm can lead to palpitations, fatigue, shortness of breath, and an increased risk of stroke.
A-Fib is more prevalent in older adults and people with conditions such as high blood pressure, obesity, diabetes, and heart disease. Recognizing the symptoms of A-Fib is crucial for early diagnosis and treatment. Besides palpitations, other symptoms include lightheadedness, chest pain, and weakness.
“The American Heart Association (AHA) emphasizes the importance of managing A-Fib through medication, lifestyle changes, and, in some cases, medical procedures such as cardioversion or ablation. Medications can help control heart rate and prevent blood clots, reducing the risk of stroke. Lifestyle changes include maintaining a healthy weight, eating a balanced diet, and avoiding smoking and excessive alcohol consumption.”
If you suspect you have A-Fib, seek prompt medical attention. Early diagnosis and treatment can help manage the condition and reduce the risk of complications. Regular check-ups with a healthcare provider are essential for monitoring heart health and detecting any abnormalities.
3.4. Heart Disease
Heart palpitations can be a symptom of various forms of heart disease, including issues with the heart’s valves, muscles, or arteries. Conditions like mitral valve prolapse, cardiomyopathy, and coronary heart disease can disrupt the heart’s normal rhythm and cause palpitations. These underlying heart conditions require thorough evaluation and management to prevent further complications.
Mitral valve prolapse, where the mitral valve doesn’t close properly, is a common structural heart problem that can lead to palpitations. Cardiomyopathy, which involves abnormalities in the heart muscle, can also cause irregular heartbeats. Coronary heart disease, characterized by the narrowing of arteries due to plaque buildup, can lead to arrhythmias and palpitations due to reduced blood flow to the heart.
“According to the National Heart, Lung, and Blood Institute (NHLBI), early detection and management of heart disease are crucial for preventing serious complications such as heart attack, stroke, and heart failure. Diagnostic tests such as electrocardiograms (ECGs), echocardiograms, and stress tests can help identify underlying heart conditions.”
If you experience frequent or persistent palpitations, especially if you have risk factors for heart disease, consult a cardiologist for a comprehensive evaluation. Treatment options for heart disease-related palpitations vary depending on the underlying condition and may include medications, lifestyle changes, or medical procedures.
3.5. Overactive Thyroid
An overactive thyroid, or hyperthyroidism, occurs when the thyroid gland produces excessive amounts of thyroid hormone. This hormonal imbalance can increase metabolism, leading to a rapid heart rate and palpitations. Hyperthyroidism is relatively easy to diagnose through blood tests and can be effectively managed with medication.
Thyroid hormones regulate many bodily functions, including heart rate. When thyroid hormone levels are too high, the heart beats faster and more forcefully, which can cause palpitations. Other symptoms of hyperthyroidism include weight loss, anxiety, sweating, and tremors.
“The American Thyroid Association (ATA) notes that hyperthyroidism can be caused by various factors, including Graves’ disease, thyroid nodules, and thyroiditis. Treatment options include antithyroid medications, radioactive iodine therapy, and, in some cases, surgery.”
If you experience palpitations along with other symptoms of hyperthyroidism, consult your healthcare provider for a thyroid function test. Medications can help regulate thyroid hormone levels and alleviate palpitations. Regular monitoring of thyroid function is essential for managing hyperthyroidism and preventing complications.
4. When Should I Get Evaluated by a Specialist?
While occasional heart palpitations are usually harmless, it’s important to seek medical evaluation if you experience frequent, persistent, or severe palpitations. Consulting a cardiologist can help determine if there’s an underlying heart condition or other medical issue causing the irregular heartbeats. Early diagnosis and treatment are essential for preventing complications and improving overall heart health.
During your evaluation, the cardiologist will conduct a thorough medical history, physical examination, and diagnostic tests such as an electrocardiogram (ECG), echocardiogram, and Holter monitor. These tests can help identify arrhythmias, structural heart abnormalities, and other conditions that may be contributing to your palpitations.
“According to the American College of Cardiology (ACC), certain symptoms should prompt immediate medical attention, including chest pain, shortness of breath, dizziness, and fainting. These symptoms may indicate a more serious heart condition that requires prompt treatment.”
Don’t hesitate to seek medical advice if you’re concerned about your heart palpitations. A cardiologist can provide personalized recommendations for managing your condition and improving your quality of life. Regular check-ups and proactive management of heart health are essential for maintaining overall well-being.
