How do you define abnormal heart rhythms?

Ekg: Simple office test that can determine the rhythm of the heart.....Many different types of rhythm, not all are serious but exact definition is very important.

Depends: An abnormal heart rhythm is one that beats too slow, too fast or irregular. I would suggest seeing your primary care physician or a cardiologist for evaluation.

Arrhytmia: Any abnormal heart rhythm is more acuretly called a dysrhthmia which ranges from benign extra beats to more lethal heart rhythms that require medications or defibrillators to treat.

Many different types: A normal heart beat is regular like a clock ticking. There are many different types of abnormal heart rhythms. The heart rhythm could be either too fast, too slow or have some type of irregularity or skipping. Some of these abnormal rhythms are not serious. Some irregular rhythms are potentially dangerous. The best way to check is call you doctor and have an ekg or heart monitor performed.
