An arrhythmia is a fast, slow, extra, or skipped heartbeat. Normal irregular heartbeats pose no risk.

Heart arrhythmias fall into two categories. First, heartrate. Bradyarrhythmia is a slow heartbeat.

Atrial fibrillation is common. CDC estimates 6 million Americans have AFib.

"The heart is a muscular pump," says Dr. Joseph H. Levine of St. Francis Hospital in Long Island, New York.

Signs and Symptoms Slow Heart Rhythm – Fatigue. – Syncope (fainting). – Dizziness.

Fast Heart Rhythm – Palpitations (feeling of a fast-beating or pounding heart). – Lightheadedness or syncope. – Shortness of breath on exertion. – Anxiety sensation. – Chest pain.

Causes Heart or vascular conditions such as coronary artery disease, high blood pressure, heart muscle changes, or cardiomyopathy, and heart valve disorders can lead to arrhythmias.

Levine advises cardiology patients to ask if a centre offers all procedures and has experience in all areas. Ask about success and complication rates, which should be above average.
