Heart rhythm problems (cardiac arrhythmias) occur when the electrical impulses that coordinate the heartbeat do not work properly, which causes the heart to beat too fast, too slowly or irregularly.
Cardiac arrhythmias can cause you to have a fluttering sensation in the chest or an accelerated heart and may be harmless. However, some cardiac arrhythmias can cause annoying and sometimes deadly signs and symptoms.

Often, the treatment of cardiac arrhythmias can control or eliminate irregular, slow or accelerated heartbeats. In addition, because cardiac arrhythmias get worse or are even caused by a weak or damaged heart, you can reduce the risk of arrhythmias if you adopt a heart-healthy lifestyle.
