A healthy heart at rest beats an average of 60 to 100 times per minute in a steady, synchronized manner. Physical activity can increase the heart rate, but if you’re healthy, the rhythm will still be steady and consistent. However, abnormal heart rhythms, known as arrhythmias, can develop at any age. An arrhythmia is an electrical problem and is usually treated by an electrophysiologist. During an arrhythmia, the heart can beat too slowly, too quickly or with an irregular rhythm. There are several different types of arrhythmias, but one of the most common is atrial fibrillation (AFib). Patients with AFib experience episodes in which the upper chambers (atria) of the heart beat out of synch with the lower chambers (ventricles). AFib and other arrhythmias are usually first treated with medications designed to maintain a controlled and consistent heartbeat. If medications aren’t enough, an arrhythmia may be treated with ablation, the pinpoint destroying of the tiny piece of tissue generating the abnormal rhythm. An implantable cardiac device (ICD) or pacemaker also may be necessary to detect abnormal rhythms and restore a...more
