Chemical cardioversion

Chemical cardioversion is a medical procedure that uses medication to restore a normal heart rhythm in patients with certain types of abnormal heartbeats, specifically arrhythmias. This procedure is often used when the heart is beating too fast (tachycardia) or irregularly (fibrillation).

Overview

Chemical cardioversion is a non-invasive procedure that can be performed in a hospital or outpatient setting. It is often used as a first-line treatment for patients with new-onset or infrequent arrhythmias. The goal of chemical cardioversion is to restore the heart's normal rhythm and prevent complications such as stroke or heart failure.

Procedure

During chemical cardioversion, medications known as antiarrhythmics are administered intravenously or orally. These medications work by slowing the electrical signals in the heart, which can help to restore a normal rhythm. The specific medication used will depend on the type of arrhythmia and the patient's overall health.

Risks and Complications

While chemical cardioversion is generally safe, it does carry some risks. These can include allergic reactions to the medication, worsening of the arrhythmia, and in rare cases, life-threatening complications such as ventricular fibrillation. Patients should discuss these risks with their healthcare provider before undergoing the procedure.

Aftercare

Following chemical cardioversion, patients are typically monitored for a short period to ensure that the heart rhythm remains stable. Regular follow-up appointments are also important to monitor for any recurrence of the arrhythmia.
