Abnormal Heartbeat (Arrhythmias)

When it comes to your heart, every beat matters. At Kettering Health Network, we don't miss a beat so you won't either. Trust your heart to the experienced heart care team at Kettering Health Network for diagnosing and treating your irregular heartbeat.


Normal hearts beat at a rate of approximately 60 to 100 times per minute. An abnormal rhythm or cardiac arrhythmias is the disturbance of the normal rhythms of a heartbeat. The rhythm can either be too fast, too slow or irregular. An arrhythmia is caused by a problem with the electrical signals that tell your heart muscle when to contract. Other problems that arise from this condition include the heart's ability to properly pump blood from its upper or lower chambers. This can reduce blood flow to vital organs, leaves the blood stagnate, which may cause clots that can travel to other parts of the body, and cause blockage to the limbs, brain or heart.
