Paroxysmal supraventricular tachycardia in the elderly

PSVT refers to tachycardia that originates in the atrial or atrioventricular junction. Most are due to reentrant excitement, and a few are caused by increased autonomy and triggered activities. The electrocardiogram is more than 3 consecutive premature supraventricular beats called paroxysmal supraventricular tachycardia. Including atrial and junctional tachycardia, which are sometimes difficult to distinguish on the electrocardiogram, are collectively referred to as paroxysmal supraventricular tachycardia.
