Does it feel like your heart is racing, fluttering or beating too slowly?

Heart arrhythmias occur when the heart’s electrical system isn’t working properly, and you experience a problem with the rate or the rhythm of your heartbeat. Arrhythmias can take many forms, including a heartbeat that is too fast (tachycardia) or too slow (bradycardia). A person experiencing arrhythmia may suffer many different symptoms including lightheadedness or dizziness; shortness of breath; sweating; or chest pain.

Most arrhythmias are harmless, but some can be serious or even life threatening.

There are many factors that can affect your heart's rhythm, including high blood pressure, smoking, substance abuse and stress, as well as previous heart issues, such as a heart attack. Your doctor will run a series of tests to determine if you are experiencing an arrhythmia. Treatments to correct this condition may include medicine if the condition is mild, or if more severe, implantation of a device in your chest, such as an implantable cardioverter-defibrillator (ICD) or pacemaker; or surgery.
