Overview
A heart rhythm disorder, or arrhythmia, is an issue with the heart’s electrical system that causes an abnormal heartbeat. There are three main types. Your heart may beat too quickly (tachycardia), too slowly (bradycardia) or irregularly.
Not all arrhythmias are dangerous. But some could signal a more severe heart problem.
The most common heart rhythm disorders are:
- Atrial fibrillation (AFib)
- Atrial flutter
- Atrioventricular block
- Bradycardia
- Sick sinus syndrome
- Supraventricular tachycardia (SVT)
- Ventricular tachycardia
- Wolff-Parkinson-White syndrome
Heart Rhythm Disorder Symptoms
Many arrhythmias don’t cause symptoms. You may learn you have one during a routine exam at a primary care visit.
If you do notice unusual signs, talk to your doctor immediately. Symptoms can include:
- Chest pain
- Dizziness
- Fainting
- Palpitations, which feel like your heart is fluttering, pounding, racing or skipping beats
- Shortness of breath
- Slow heartbeat
