What are Arrhythmias?
Arrhythmias are problems that affect the electrical system, or “wiring”, of the heart muscle. This causes you to have an abnormal heartbeat that is too fast, too slow, and/or irregular. You may feel your heart “flutter” or feel like it skipped a beat- these are all symptoms of cardiac arrhythmia. Other symptoms can include dizziness, lightheadedness, fainting, chest pain or shortness of breath. Many arrhythmias are benign, meaning they do not require urgent treatment, but that fluttery feeling can also signal a life-threatening condition. You may need an electrophysiology study (EP study) for further evaluation.
You may feel like your heart is beating too fast, a condition known as tachycardia, or like it is beating too slowly, called bradycardia.
Common arrhythmias include:
