The average age for heart arrhythmia (irregular heartbeat) can vary significantly depending on the type and cause of the arrhythmia. Generally, heart arrhythmias can occur in people of any age, but they are more common in older age groups. Atrial fibrillation, the most common type of arrhythmia, typically occurs in people over the age of 65 and is estimated to affect about 2.7 million Americans over the age of 65. Ventricular tachycardia, another common type of arrhythmia, is more common in people over the age of 40, particularly those with underlying heart disease. Other types of arrhythmias, such as AV block and supraventricular tachycardia, are more common in younger age groups, particularly in infants and children.
In general, heart arrhythmias can be caused by an underlying medical condition (such as high blood pressure or coronary artery disease) or by certain medications, or they can occur in otherwise healthy people. Some arrhythmias are benign and don’t require any treatment, while others can be serious and require medical intervention. It is important to discuss any symptoms of arrhythmia with your doctor so that they can determine the best course of treatment.
