MAX - SHOCK Clinical Trial

Comparison of Maximum Energy Shocks From Two Defibrillator Vendors MAX - SHOCK- A Randomized Controlled Clinical Trial

Sponsor

Ottawa Heart Institute Research Corporation

Enrollment

376 participants

Start Date

Mar 31, 2025

Study Type

INTERVENTIONAL

Conditions

Atrial Fibrillation Cardioversion

Summary

Can Electrical Cardioversion (ECV) for AF be improved. It is the preferred method to restore sinus rhythm in patients with AF in whom a rhythm-control strategy is pursued. Hypothesis: ECV success rates will be greater with a biphasic defibrillator with maximum energy of 360J (® Physio-Control) compared to a biphasic defibrillator with maximum energy of 200J (® Zoll)

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study (called MAX-SHOCK) is testing the best way to perform electrical cardioversion — a procedure that uses a controlled electric shock to reset an irregular heart rhythm (atrial fibrillation) back to a normal rhythm — by comparing different levels of electrical energy. **You may be eligible if...** - You are older than 18 - You have persistent atrial fibrillation (irregular heartbeat that hasn't corrected on its own) - You are scheduled for a planned (elective) cardioversion procedure at the study hospital - You are a patient under the care of the Electrophysiology team at the study center **You may NOT be eligible if...** - You have a blood clot in your heart's left atrial appendage - You have a medical reason preventing blood thinners (anticoagulation) - You are participating in another randomized trial Talk to your doctor to see if this trial is right for you.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.
