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 FibrillationCardioversion

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

Inclusion Criteria4

  • Patients age \> 18 years.
  • Persistent atrial fibrillation.
  • Scheduled for elective cardioversion at UOHI
  • Patient is within the circle of care of UOHI Electrophysiology staff

Exclusion Criteria3

  • Known left-atrial appendage thrombus.
  • Contraindication to appropriate anticoagulation.
  • Patient is included in another randomized clinical trial.
