Delivery of an electrical current timed for delivery during the QRS complex is called synchronized cardioversion.
<h3>
What is Cardioversion?</h3>
Cardioversion is a medical procedure that uses electricity or drugs to restore an abnormally fast heart rate (tachycardia) or other cardiac arrhythmias to a normal rhythm. Cardioversion therapy is to treat those who suffer from atrial fibrillation or atrial flutter, unstable supraventricular tachycardia, which could lead to ventricular fibrillation.
Synchronized cardioversion provides a low-energy synchronized shock using a sensor that detects the highest point of the R-wave(peak of the QRS complex) that can restore the activity of the electrical conduction system of the heart. It is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter.
Therefore, delivery of an electrical current timed for delivery during the QRS complex is called synchronized cardioversion.
