Irregular heartbeat causes in adults7/16/2023 However, this is a medical emergency for those who have heart issues. If someone has an otherwise healthy heart, this may not cause serious problems. The heart can’t pump blood to the rest of the body. Ventricular tachycardia is a regular but rapid heartbeat that doesn’t allow the ventricles to fill with blood. Those who have ventricular fibrillation generally have heart disease or have suffered serious trauma to the heart. This is potentially a deadly condition if the normal heart rhythm is not restored in minutes. Ventricular fibrillation causes the ventricles to quiver rather than contract and pump the blood to the rest of the body. Supraventricular tachycardia refers to arrhythmia that begins above the ventricles and causes palpitations that start and end abruptly. The beats are more organized than atrial fibrillation, but this is also linked to stroke. Atrial flutter is another type of tachycardia. Several types of tachycardia exist, as noted below.Ītrial fibrillation causes a chaotic, rapid, and uncoordinated heart rate, which is associated with stroke. Tachycardia refers to a resting heart rate that is higher than 100 beats per minute. The problems come when the resting heartbeat is too fast, slow, or erratic. The heart rate slows while sleeping and speeds up during exercise, for example. Keep in mind that it’s normal for a person’s heart rate to change during various activities. Any of these issues could affect your body. It may also beat too fast (tachycardia) or too slow (bradycardia). Types of Heart ArrhythmiaĪrrhythmia can cause one of three issues. Sometimes, heart arrhythmias can be harmless, but they may indicate serious and potentially life-threatening issues. Arrhythmia occurs when those electrical signals are not working properly.
