An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
Some people describe arrhythmias as fluttering or thumping feelings or skipped beats in their chests. These feelings are called palpitations.
Some arrhythmias can cause your heart to suddenly stop beating. This condition is called sudden cardiac arrest (SCA). SCA causes loss of consciousness and death if it’s not treated right away.
