Causes And Risk Factors Of Paroxysmal Supraventricular Tachycardia

Atrial Fibrillation

Atrial fibrillation is another condition where the heart beats abnormally. In this case, the muscles of the heart fibrillate, or quiver. As with paroxysmal supraventricular tachycardia, the heart’s electrical system does not function the way it should, and the muscles in the atria quiver instead of contract. This also causes an abnormally rapid heartbeat. The rate can rise to as much as 160 beats per minute. The symptoms of atrial fibrillation and PSVT are also similar, with dizziness, shortness so of breath, chest pain and faintness. However, unlike most cases of paroxysmal supraventricular tachycardia, atrial fibrillation can be dangerous. Complications include blood clots, congestive heart failure, and other heartbeat abnormalities. Stroke is also a risk with atrial fibrillation. The disorder is more likely to be the cause of abnormal heart rate in individuals over sixty-five than PSVT.
