Irregular Heartbeat: Causes, Types & When to See a Doctor

What Is Irregular Heartbeat?

An irregular heartbeat (arrhythmia) means your heart beats too fast, too slow, or in an uneven rhythm. Many arrhythmias are harmless, but some can affect blood flow and lead to serious health issues. Atrial fibrillation is the most common serious arrhythmia.

Common Causes of Irregular Heartbeat

• Atrial fibrillation
• Premature heartbeats (PVCs)
• Caffeine or alcohol
• Stress and anxiety
• Heart disease
• Electrolyte imbalances

When to See a Doctor

See a doctor if you frequently notice irregular heartbeats, especially with dizziness, fainting, shortness of breath, or chest discomfort. Seek emergency care for sustained irregular rhythm with severe symptoms.

Warning Signs That Need Immediate Attention

Frequently Asked Questions

Are irregular heartbeats dangerous?

Many irregular heartbeats (like occasional premature beats) are harmless. Atrial fibrillation increases stroke risk and needs treatment. The danger depends on the type of arrhythmia and your overall heart health.

What is atrial fibrillation?

Atrial fibrillation (AFib) is an irregular, often rapid heart rhythm in the upper chambers. It increases stroke risk by 5 times because blood can pool and form clots. Effective treatments include blood thinners and rhythm control medications.

Can you feel an irregular heartbeat?

Some people feel every irregular beat as a flutter, skip, or thud. Others have arrhythmias with no symptoms at all. Smartwatches and ECG monitors can help detect irregular rhythms you might not feel.

What causes PVCs?

Premature ventricular contractions (PVCs) are extra heartbeats that feel like skipping. They are usually harmless and triggered by caffeine, stress, alcohol, or lack of sleep. Frequent PVCs (more than 10-15% of beats) should be evaluated.

How much does arrhythmia testing cost?

An EKG costs $50-$300. A Holter monitor costs $200-$500. An echocardiogram costs $500-$2,000. A cardiologist visit costs $200-$500. OpenMyPro helps you find affordable cardiac specialists.
