Arrhythmia is a term used to describe any irregularity or abnormality in the heartbeat. It is a common heart rhythm disorder, and several different types of arrhythmias can occur. The most common type of arrhythmia is atrial fibrillation (AFib). AFib occurs when the electrical signals that control your heartbeat are out of sync, causing the heart to beat too quickly, too slowly, or irregularly. It is the most common type of arrhythmia, affecting millions of people around the world. Other common types of arrhythmias include supraventricular tachycardia (SVT), ventricular tachycardia (VT), and bradycardia. SVT is an abnormally fast heartbeat originating in the upper chambers of the heart. VT is an abnormally fast heartbeat originating in the lower chambers of the heart. Bradycardia is an abnormally slow heartbeat.
Arrhythmias can range from harmless to life-threatening, and the type and severity of the arrhythmia can determine the appropriate treatment. Some arrhythmias require no treatment, while others may require medication or surgery. It is important to speak with your doctor if you experience any symptoms of an arrhythmia, such as a racing or skipped heartbeat, palpitations, chest pain, fainting, or shortness of breath.
