Cardioversion

Cardioversion is a procedure designed to restore the heart's normal rhythm using high-energy shocks. It's often used to treat irregular heartbeats, such as Atrial Fibrillation

Typically, each heartbeat originates in the right atrium, where specialized pacemaker cells generate organized electrical signals, resulting in a rhythmic heartbeat.

In arrhythmias like atrial fibrillation, the atria quiver due to chaotic electrical signals, leading to inefficient blood pumping and an irregular heartbeat. Symptoms can include fainting, shortness of breath, dizziness, and fatigue. In severe cases, it may lead to stroke, heart attack, or sudden cardiac death.

Based on your medical history and symptoms, your cardiologist might suggest cardioversion to restore normal rhythm. During electrical cardioversion, a high-energy shock is applied to reset the heart's electrical activity.

A cardiologist performs the cardioversion with the assistance of an anesthetist and nursing staff. An IV line is placed in your arm to administer medication, putting you into a light sleep. Your electrocardiogram, oxygen levels, and vital signs are monitored throughout. The procedure typically lasts only a few minutes.

During cardioversion, a synchronised electrical shock is delivered to the heart through electrodes placed on the chest. This shock interrupts abnormal electrical circuits, allowing the heart to reset to a normal rhythm. The shock causes all heart cells to contract simultaneously, effectively restoring a normal heartbeat without causing damage.
