What is synchronized cardioversion and when is it used?
Basically synchronized cardioversion is shocking at a particular point in the sinus rhythm. It is used for supraventricular tachycardia and atrial fibrillation / flutter. These are rhythms the AED is not programmed to shock; recall AED shocks for VF and VT. See the related link.
What is synchronized cardioversion?
From the related link, Synchronized Cardioversion is: --A controlled form of defibrillation for patients who still have organized cardiac activity with a pulse.

The use of electrical shock to restore the heart's normal rhythm is known as?
Defibrillation also known as cardioversion.
What potential exists for a cardioversion to fail?
Unfortunately, in a number of cases, the heart prefers its abnormal rhythm and reverts to it despite cardioversion.
Where on the cardiac cycle does a synchronized shock land?
A synchronized cardioversion shock is delivered a few milliseconds after the R wave on the EKG. The R wave represents ventricular depolarization, which is followed by mechanical contraction of the ventricle. Therefore, it can be seen that a synchronized shock will occur during ventricular contraction, or during ventricular systole, to completely depolarize the myocardium and try to restore a normal rhythm.
What does a cardioversion accomplish?
Cardioversion is used to stop this abnormal beating so that the heart can begin normal rhythm and pump more efficiently.
Why is it often necessary to repeat cardioversion?
in about 50% of cases, the heart prefers its abnormal rhythm and reverts to it within one year, despite cardioversion.
What is procedure to treat different types of disruptions in the normal heart rhythm?
Cardioversion
What is the term for sharing a common rhythm?
Synchronized
What is electrical cardioversion?
Cardioversion, the electric shock to the chest wall, is usually performed emergencies. This device briefly suspends the heart's activity and allows it to return to a normal rhythm
What takes place in the process of cardioversion?
During the process of cardioversion, an electrical shock is delivered to the heart in an attempt to change an irregular heart beat rhythm into a normal one.
