When you have a slow heart rate and your heart is not pumping enough blood, you may have a type of bradycardia. If you are physically fit, your heart may still be able to pump enough blood to your body with under sixty beats per minute at rest. However, in those with heart disease, ventricular tachycardia may be a medical emergency that requires immediate medical treatment.Īlthough a heart rate under sixty beats per minute at rest is considered bradycardia, a low resting heart rate does not always indicate an issue. Ventricular tachycardia may not cause severe problems in individuals with a healthy heart. Consequently, the heart has difficulty pumping sufficient blood to the body. As a result, the fast heart rate does not allow the ventricles to fill correctly with blood. This rapid, regular heart rate begins with faulty electrical signals in the lower chambers of the heart (ventricles). Most individuals who have ventricular fibrillation have underlying heart disease or have suffered severe trauma. This severe condition may lead to death if not achieving to restore regular heart beating within minutes.
This kind of arrhythmia happens when rapid, chaotic electrical signals cause the lower chambers of the heart, the ventricles, to quiver instead of making contact in a coordinated manner to pump blood to the rest of the body. Supraventricular tachycardia causes episodes of pounding heartbeats (palpitations) that begin and end abruptly. Supra means above ventricular refers to the heart’s lower chambers or ventricles.
It is a broad term that includes arrhythmias that begin in the atria, the heart’s upper chambers. Atrial flutter is also related to stroke. It is similar to atrial fibrillation, but the heartbeat is more organized. In addition, experts associate atrial fibrillation with serious complications, such as stroke. The condition may be temporary, but some episodes of atrial fibrillation may not stop unless treated. It is advisable to tell your physician whenever you feel your heart racing, if you feel dizzy, drowsy, or lightheaded, or if you have chest pain.Ĭhaotic cardiac signaling causes a rapid, uncoordinated heart rate. Most individuals with an irregular heartbeat can lead a normal life if it is properly diagnosed. Treatment of irregular heartbeat or cardiac arrhythmia may include medications, catheter procedures, implanted devices, or surgery to control or eliminate slow, fast, or irregular heartbeats.Ī heart-healthy lifestyle may help prevent heart damage that may trigger certain cardiac arrhythmias. For example, the heart rate may decrease during sleep or increase while exercising. Sometimes, however, it is normal for an individual to have a slow or fast heart rate. However, some abnormal heart beatings can cause bothersome, sometimes even life-threatening, signs and symptoms. This malfunctioning message causes the heart to beat too fast (tachycardia), too slow, or abnormally.Īn irregular heartbeat may feel like a pounding or racing heart and may be harmless. Heart rhythm issues, or cardiac arrhythmias, occur when the electrical signals that coordinate the heartbeat do not work correctly. Several different conditions may cause your heart to beat abnormally, and treatment depends on the cause. When you have an arrhythmia, your heart may beat faster or slower than others without an arrhythmia. C auses and Treatments of Irregular HeartbeatĪ cardiac arrhythmia is an unusual or irregular heartbeat.
