Cardioversion is a medical procedure used to restore a normal heart rhythm in individuals experiencing certain types of abnormal heartbeats, known as arrhythmias. It can be performed using electrical shocks or medications. Electrical cardioversion involves delivering a controlled electric shock to the heart, while pharmacological cardioversion uses specific drugs to help reset the heart's rhythm. The procedure is typically done in a hospital setting and requires monitoring by healthcare professionals. Patients may receive sedation to ensure comfort during the process. After cardioversion, doctors will monitor the heart's rhythm to ensure it remains stable and assess the need for further treatment.
