Overview

Palpitations are the sensation that your heart is beating too hard, too fast, skipping beats, or fluttering. An arrhythmia is any change from the heart’s normal rhythm. Not every palpitation means you have an arrhythmia, and many arrhythmias are harmless. Evaluation helps determine the cause, assess risk, and decide whether treatment or further monitoring is needed. This process is common, reassuring for most people, and focuses on keeping you safe and informed.

Signs & Symptoms

People describe palpitations in different ways. Common experiences include a racing or pounding heartbeat, a fluttering feeling in the chest or neck, skipped or extra beats, or a sense that the heart is flipping or thumping. Symptoms may last seconds to minutes or longer and can occur at rest, during activity, or with stress. Some people also notice lightheadedness, mild shortness of breath, or chest discomfort. Keep a simple log of when symptoms happen, what you were doing, and how long they lasted—this information is very helpful for your clinician.

• Racing or pounding heartbeat
• Fluttering or flip-flop sensation in the chest
• Skipped or extra beats
• Awareness of heartbeat at rest or during activity
• Possible associated lightheadedness or mild breathlessness

Causes & Risk Factors

Many everyday factors can trigger palpitations without a serious arrhythmia. These include caffeine, alcohol, nicotine, stress or anxiety, lack of sleep, dehydration, fever, pregnancy, and certain over-the-counter cold medicines or supplements. Medical causes include thyroid disorders, anemia, low blood sugar, electrolyte imbalances, and heart conditions such as atrial fibrillation, premature beats, or other rhythm disorders. Risk factors that raise the chance of a clinically important arrhythmia include older age, high blood pressure, heart disease, diabetes, sleep apnea, excess alcohol use, and a family history of rhythm problems.

Diagnosis

Evaluation begins with a detailed history and physical exam. Your clinician will ask about symptom pattern, triggers, medical history, medicines, and family history. An electrocardiogram (ECG or EKG) records the heart’s electrical activity at rest and is often the first test. If symptoms are infrequent, you may wear a Holter monitor (usually 24–48 hours) or an event/patch monitor for longer periods to capture the rhythm during palpitations. Blood tests check for thyroid problems, anemia, and electrolytes. An echocardiogram (ultrasound of the heart) looks at structure and pumping function when needed. In selected cases, exercise stress testing, longer-term implantable monitors, or electrophysiology studies may be recommended. The goal is to match symptoms with the actual heart rhythm and assess overall risk.

Treatment & Management

Treatment depends on the cause and how bothersome or risky the rhythm is. If no serious arrhythmia is found and triggers are identified, simple lifestyle changes often help. For confirmed arrhythmias, options may include medicines to control rate or rhythm, blood thinners if atrial fibrillation raises stroke risk, procedures such as catheter ablation for certain rhythm problems, or devices in selected higher-risk cases. Your care team will explain benefits, risks, and follow-up. Many people feel much better once the cause is identified and a clear plan is in place.

• Address reversible triggers (caffeine, alcohol, stress, sleep, medicines)
• Treat underlying conditions such as thyroid disease or anemia
• Medications for rate or rhythm control when needed
• Catheter ablation or other procedures for selected arrhythmias
• Regular follow-up and shared decision-making with your clinician

Living With It

Most people with palpitations lead full, active lives after evaluation. Focus on heart-healthy habits: regular physical activity as approved by your clinician, a balanced diet, good sleep, stress-management techniques (such as breathing exercises or mindfulness), limiting caffeine and alcohol, and not smoking. Keep scheduled appointments and report new or worsening symptoms promptly. Wear any prescribed monitor as directed and bring your symptom log to visits. Emotional support matters—anxiety about heart symptoms is common and treatable. Ask questions until you feel confident about your plan. With accurate diagnosis and practical self-care, many people experience fewer symptoms and greater peace of mind.
