Some cases of symptomatic PSVT in affected individuals require treatment through a procedure called electrical cardioversion. Electrical cardioversion is the use of electrical shocks to restore a normal heart rhythm. This is a procedure performed in a hospital setting under the effects of intravenous sedation. Large patches containing electrodes are placed on the patient's chest and are connected to a device called a cardioversion machine. This machine is a type of specialized defibrillator with the ability to record the patient's heart rhythm during the procedure. It also delivers electrical shocks to the heart to help restore a normal heart rhythm. This machine is also capable of correcting bradycardia following the cardioversion procedure if that complication occurs. Some individuals with PSVT will require repeat cardioversion procedures to maintain normal heart rhythm. The concept behind this treatment is similar to how a portable defibrillator works in the event of a cardiac emergency, but it is done in a more carefully controlled and monitored process.
