Causes, Symptoms, and Testing Methods for Cardiac Arrhythmias


A cardiac arrhythmia is a clinical term for a problem with the rate or rhythm of an individual’s heartbeat. During an arrhythmia, the heart may beat too quickly, too slowly, or irregularly. While some arrhythmias are harmless, others may become life-threatening if the body is unable to pump enough blood to the vital organs. Read on to learn more about causes, symptoms, and how your cardiologist can test for this medical issue.

The heart has an internal electrical system that controls your heartbeat’s rate and rhythm. This highly complex system causes an electric signal to travel through the heart each time it contracts and pumps blood. This signal travels from your heart’s upper right atrium to the left atria, which then contract and pump blood into the ventricles. Finally, the ventricles contract and pump blood to the rest of the body. Cardiac arrhythmias can be caused by a problem at any stage of this intricate process.

Common symptoms of a heart arrhythmia include a fluttering in the chest or a slow heartbeat. Some patients also complain of chest pain, shortness of breath, or dizziness or lightheadedness. Because many of these symptoms are similar to those of a heart attack, call 911 immediately if you suddenly or frequently experience one of these signs.

Because some arrhythmias have no apparent signs or symptoms, your heart doctor may discover that you have an arrhythmia before you do. To help ensure good heart health, schedule routine examinations with your cardiologist. If you experience any symptoms of arrhythmia, visit your doctor and undergo diagnostic testing.
