Does your heart sometimes feel like it’s racing, skipping beats, or fluttering? You’re not alone. Many people experience heart palpitations, and while they’re often harmless, they can sometimes be a sign of a serious condition. Knowing when to worry and seek medical attention could save your life. In this comprehensive guide, Dr. Nageswara Rao Goteti, a leading interventional cardiologist, shares his expertise to help you understand heart palpitations, their causes, and the signs that require immediate medical attention.

What Are Heart Palpitations?

Heart palpitations are sensations that make you acutely aware of your heartbeat. They may feel like your heart is racing, pounding, fluttering, or skipping beats. Although these sensations are often temporary and harmless, they can sometimes indicate underlying health issues.

How Do Palpitations Feel?

Each person experiences heart palpitations differently. Some common descriptions include:

• A racing heartbeat, as if you’ve just run a marathon while sitting still.
• A fluttering sensation in the chest, resembling the flapping of butterfly wings.
• A pounding heartbeat that echoes throughout the chest and neck.
• Skipped or extra beats that disrupt the heart’s regular rhythm.

Common Causes of Heart Palpitations

The causes of heart palpitations can range from benign lifestyle factors to serious medical conditions. Understanding these triggers can help you manage or prevent them.

Lifestyle Triggers

Several everyday habits and circumstances can lead to palpitations, including:

• Excessive caffeine consumption: Found in tea, coffee, energy drinks, and chocolate.
• Heavy or spicy meals: These can trigger digestive-related palpitations.
• Dehydration: A common issue in India’s hot climate, dehydration affects heart rhythm.
• Sleep disturbances: Irregular sleep patterns or insomnia can overstimulate the heart.
• Substance use: Smoking, alcohol, and recreational drugs are known triggers.
• Intense physical activity: Strenuous exercise without proper hydration or rest.

Medical Conditions

Certain health conditions can also cause palpitations, such as:

• Anxiety and stress: Emotional stress or panic attacks often trigger palpitations.
• Thyroid disorders: Both hyperthyroidism and hypothyroidism can affect heart rate.
• Anemia: Reduced oxygen in the blood can make the heart work harder.
• Low blood sugar: Hypoglycemia can lead to irregular heartbeats.
• Hormonal changes: Pregnancy, menstruation, or menopause can induce palpitations.
• Fever: Elevated body temperature increases the heart rate.
• Side effects of medications: Including decongestants, certain antihistamines, and even herbal supplements.

When Should You Worry About Heart Palpitations?

Most palpitations are harmless, but certain symptoms require immediate medical attention. Recognizing these warning signs can make all the difference.

Warning Signs Requiring Immediate Medical Attention

Seek emergency care if palpitations are accompanied by:

• Chest pain or discomfort: This could indicate a heart attack.
• Severe shortness of breath: Difficulty breathing may signal heart or lung issues.
• Dizziness or lightheadedness: A sign of inadequate blood flow to the brain.
• Fainting or near-fainting episodes: This could indicate a severe arrhythmia.
• Confusion or disorientation: This may occur due to insufficient oxygen delivery.
• Profuse sweating: Especially if unrelated to physical activity.
• Pale or clammy skin: This suggests circulatory problems.

High-Risk Scenarios

Be extra cautious if you:

• Have a history of heart disease.
• Are over the age of 60.
• Have risk factors like diabetes, hypertension, or obesity.
• Experience palpitations during physical exertion.
• Notice palpitations lasting longer than a few minutes.

Diagnosing Heart Palpitations

When you visit a cardiologist, they will conduct a detailed evaluation to identify the cause of your palpitations.

Initial Assessment

Your doctor will:

• Take a comprehensive medical history to assess risk factors.
• Perform a physical examination focusing on your heart and lungs.
• Check vital signs, including blood pressure and pulse rate.
• Order blood tests to check for anemia, thyroid issues, or electrolyte imbalances.

Advanced Diagnostic Tests

Depending on the initial findings, your doctor may recommend:

• Electrocardiogram (ECG): A snapshot of your heart’s electrical activity.
• Holter monitor: A 24-48 hour recording of your heart rhythm.
• Event recorder: For sporadic symptoms that don’t occur daily.
• Echocardiogram: An ultrasound to evaluate the heart’s structure and function.
• Stress test: To observe heart behavior during physical exertion.

Treatment and Management of Heart Palpitations

Treatment depends on the underlying cause, and it may involve both immediate measures and long-term management.

Immediate Measures

• Vagal maneuvers: Techniques like coughing or holding your breath to slow your heart rate.
• Deep breathing exercises: Help calm the nervous system.
• Hydration: Drinking water to restore balance, especially after dehydration.
• Avoidance of triggers: Caffeine, alcohol, or heavy meals.

Medical Interventions

For more persistent or severe cases, your cardiologist may suggest:

• Medications: Such as beta-blockers or anti-arrhythmic drugs.
• Treatment of underlying conditions: Addressing thyroid issues, anemia, or anxiety.
• Cardiac procedures: Like ablation therapy for arrhythmias, in rare cases.

Preventing Heart Palpitations

Making simple lifestyle changes can significantly reduce the frequency and intensity of palpitations.

Dietary Adjustments

• Limit caffeine and alcohol consumption.
• Stay hydrated, especially in hot weather.
