Arrhythmia. An abnormal heart rhythm that may result in symptoms of palpitations, chest pain, dizziness, passing out, shortness of breath, and fatigue. Some arrhythmias can lead to strokes, heart attacks, and even death. See doctor, cardiologist, and/or heart rhythm (EP) specialist if concerned. Call 911 if chest pain, passing out, shortness of breath, or severe dizziness.
Check your pulse. . A heart arrhythmia is an irregular series of heart beats. It is not a fast or slow rate but an irregular rate. The most common arrhythmia is a premature atrial contraction (pac). A more serious arrhythmia is a premature ventricular contraction. If your pulse is irregular or your heart beats out of turn (suddenly and strongly) you are having an arrhythmia. Frequent arrythmias should be evaluated.
