Electrical Cardioversion and Clot Risk Mitigation in Houston, TX

Electrical Cardioversion Procedure

• Electrical cardioversion is a medical procedure that restores normal heart rhythm (sinus rhythm) by briefly interrupting abnormal heart rhythms like atrial fibrillation (AFib) or atrial flutter (AFL).
• It involves a controlled electric shock delivered through paddles on the chest wall, performed under sedation in a hospital setting.

Preparation for Cardioversion

• You'll receive instructions on medication management, fasting, and other essential details prior to the procedure.
• Arrange for transportation to and from the hospital for the day of the procedure.

Stroke Risk and Blood Thinners

• AFib or AFL patients face a risk of heart clot formation. During cardioversion, a clot can dislodge, potentially causing a stroke.
• Ensuring proper anticoagulant (blood thinner) use before and after the procedure is crucial to reduce stroke risk.
• In some cases, a transesophageal echocardiogram (TEE) may be scheduled just before cardioversion to rule out clots in the heart chambers.
• TEE involves passing an ultrasound probe through the esophagus to visualize the heart's chambers and assess for clots.
• If TEE reveals a clot, cardioversion will not proceed.
