An arrhythmia describes an irregular heartbeat. With this condition, a person’s heart may beat too quickly, too slowly, too early, or with an irregular rhythm.
Arrhythmias occur when the electrical signals that coordinate heartbeats are not working correctly. An irregular heartbeat may feel like a racing heart or fluttering.
Many heart arrhythmias are harmless. However, if they are highly irregular or result from a weak or damaged heart, arrhythmias can cause severe and potentially fatal symptoms and complications.
In this article, we define arrhythmia, as well as its causes and symptoms. We also explain the possible treatments and different types.
