Arrhythmia causes9/25/2023 ![]() ![]() The condition may be temporary, but some A-fib episodes may not stop unless treated. ![]() Chaotic heart signaling causes a rapid, uncoordinated heart rate. The resting heart rate is less than 60 beats a minute. Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat.The resting heart rate is greater than 100 beats a minute. Tachycardia (tak-ih-KAHR-dee-uh) is a fast heart.In general, heart arrhythmias are grouped by the speed of the heart rate. A heart-healthy lifestyle can help prevent heart damage that can trigger certain heart arrhythmias. Heart arrhythmia treatment may include medications, catheter procedures, implanted devices or surgery to control or eliminate fast, slow or irregular heartbeats. For example, the heart rate may increase with exercise or slow down during sleep. However, sometimes it's normal for a person to have a fast or slow heart rate. However, some heart arrhythmias may cause bothersome - sometimes even life-threatening - signs and symptoms. Heart arrhythmias may feel like a fluttering or racing heart and may be harmless. ![]() The faulty signaling causes the heart to beat too fast (tachycardia), too slow (bradycardia) or irregularly. Heart rhythm problems (heart arrhythmias) occur when the electrical signals that coordinate the heart's beats don't work properly. The signal then travels through the atria to the atrioventricular (AV) node and into the ventricles, causing them to contract and pump blood.Ī heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. In a typical heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal. ![]()
