Cardioversion
Cardioversion refers to the process of restoring the normal heart rhythm from an abnormal rhythm. Most elective cardioversions are performed to treat atrial fibrillation or atrial flutter – heart rhythm disturbances that originate in the upper chambers (atria) of the heart.

Why do I need a cardioversion?
Normally, each heartbeat starts in the upper right chamber (right atrium) of the heart in a region containing specialised “pacemaker” cells. Each time these cells fire (usually 1 to 2 times per second) this electrical impulse is transmitted in an organised fashion throughout the heart resulting in a coordinated rhythmic heartbeat. In patients with atrial fibrillation, instead of the normal organised electrical activity, the atria fibrillate (or quiver) because of chaotic electrical activity that circulate throughout both atria. This can result in less efficient blood pumping and an irregular or fast heartbeat.
Some patients have no symptoms, whereas others may feel rapid heart beating, shortness of breath or fatigue. Depending on your specific medical history and symptoms, you may be advised to have a cardioversion to return your heart to normal rhythm.

Atrial Flutter Ablation
In some hearts, an abnormal heart rhythm develops when an electrical impulse starts from a different location, other than the SA node, or follows a route (or pathway) that is not normally present. This is what happens in atrial flutter.

Atrial fibrillation is due to the development of electrical short circuits inside the top chambers of the heart.
