Have you ever felt your heart "flutter," "race," or "skip a beat"? This sensation is known as heart palpitations, a common experience that can be concerning. In most cases, heart palpitations are harmless and temporary, but sometimes they may indicate an underlying health problem that requires attention. Let's explore this phenomenon in depth.

What are heart palpitations?
Heart palpitations are the sensation of rapid, strong, or irregular heartbeats. You may feel them in your chest, neck, or throat. The sensation can be described in various ways, such as:
- Rapid heartbeat (Tachycardia): Feeling like your heart is beating too fast.
- Strong or "pounding" heartbeats: Feeling like your heart is beating harder than usual.
- Skipped beats or extra beats: Feeling like your heart "skipped a beat" or has "fluttering."
- Irregular heartbeat (Arrhythmia): Feeling like your heart rhythm is chaotic or irregular.
Palpitations often last a few seconds or minutes, but may persist longer in some cases.
Common and non-worrisome causes of palpitations
Frequently, palpitations are a normal body reaction and don't indicate a serious problem. Common triggers include:
- Strong emotions: Like stress, anxiety, fear, or excitement.
- Strenuous physical activity: During and after exercise.
- Stimulants: Like caffeine (in coffee, tea, energy drinks), nicotine (in cigarettes), and some medications (like decongestants or asthma inhalers).
- Fever.
- Hormonal changes: During pregnancy, menstruation, or menopause.
- Certain foods or drinks: Like alcohol, spicy foods, or those containing MSG.
- Dehydration or low blood sugar.
If palpitations occur occasionally and are associated with these triggers and resolve on their own, they're usually not a major concern. However, it's always good to discuss any new symptoms with your doctor.
When should palpitations be concerning?
You should take palpitations seriously and consult a doctor if they:
- Occur frequently or persist for long periods.
- Are accompanied by other concerning symptoms, like:
- Chest pain or pressure.
- Severe shortness of breath.
- Severe dizziness or fainting.
- Confusion.
- Leg swelling.
- You have a history of heart disease (like previous heart attack, heart failure, or valve problems).
- You have a family history of serious heart problems or sudden cardiac death.
- Begin suddenly and are very fast or noticeably irregular.
Important Medical Advice!
If palpitations are accompanied by severe chest pain, acute shortness of breath, or severe dizziness/loss of consciousness, these may be signs of an emergency. Seek immediate medical help.
Cardiac causes of palpitations
In some cases, palpitations may indicate a heart problem, such as:
- Arrhythmias: A wide range of conditions where the heart beats abnormally (too fast, too slow, or irregularly). Examples include:
- Atrial Fibrillation (AFib): The most common serious arrhythmia where the heart's upper chambers (atria) beat chaotically and fast.
- Supraventricular Tachycardia (SVT): Episodes of rapid heartbeats originating in the upper chambers.
- Ventricular Tachycardia (VT): Rapid and dangerous heartbeats originating in the lower chambers (ventricles).
- Premature Atrial/Ventricular Contractions (PACs/PVCs): Extra early beats, often benign but can be bothersome.
- Structural heart diseases: Like valve problems (stenosis or regurgitation), cardiomyopathy, or congenital heart defects.
- Coronary artery disease: When the heart muscle doesn't get enough blood.
- Heart failure: When the heart can't pump blood efficiently.
Diagnosing the cause of palpitations
To determine the cause of palpitations, your doctor will:
- Review your medical history and symptoms: When palpitations occur, what triggers them, and accompanying symptoms.
- Perform a physical exam.
- Electrocardiogram (ECG): To assess the heart's electrical activity. May be normal if you're not experiencing palpitations during the test.
- Holter monitor or event recorder: A portable ECG device worn for 24-48 hours or longer to record heart activity during daily activities, helping capture intermittent palpitations.
- Blood tests: To check electrolyte levels (like potassium, magnesium), thyroid function, and anemia.
- Echocardiogram: To evaluate heart structure and function.
- Stress test: If palpitations occur with exertion.
- Electrophysiology study (EPS): In complex cases, this test can precisely identify the source of arrhythmia.
Tips for managing palpitations and lifestyle changes
If palpitations are caused by non-cardiac factors or benign arrhythmias, these tips may help:
- Avoid known triggers: Reduce caffeine, nicotine, and alcohol.
- Manage stress and anxiety: Try relaxation techniques like deep breathing, yoga, or meditation.
- Get adequate sleep.
- Stay hydrated: Drink enough water.
- Maintain a balanced diet.
- Exercise regularly (after consulting your doctor).
If palpitations are caused by a heart problem, treatment will depend on the type and severity. It may include medications, lifestyle changes, procedures like electrical cardioversion, or even device implantation like pacemakers or implantable cardioverter-defibrillators (ICDs).
Conclusion: When to consult a cardiologist?
Heart palpitations are a common symptom, but it's important not to ignore them, especially if they're new, frequent, or accompanied by other symptoms. A cardiologist can help determine the cause and provide appropriate treatment if needed.
If you experience palpitations and are concerned, or if you have any of the warning signs mentioned, we encourage you to book an appointment for evaluation. Early diagnosis and proper treatment can significantly improve your quality of life and protect your heart health long-term.
