This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether an electrical shock procedure (called cardioversion) improves quality of life in people with persistent atrial fibrillation — a common heart rhythm problem. Before the procedure, all participants take a medication called Amiodarone and wear an activity monitor to establish a baseline. Then, half the participants randomly receive the actual electrical shock, while the other half receive a simulated procedure without the shock, and neither group knows which they received.
Doctors are uncertain whether the electrical shock itself — beyond just the medication — actually makes people feel better and live better lives. This study aims to answer that question by comparing real treatment to a placebo procedure.

You likely don't qualify if…
You would first spend 4 weeks taking heart medication (Amiodarone) and wearing an activity monitor to measure your baseline activity level. You'd also have a heart ultrasound and ECG. Then, on the procedure day, you'd be put to sleep and randomized to receive either the electrical shock or a simulated procedure — you won't know which. After waking up, you'll be blinded to your assignment and will complete quality-of-life questionnaires to measure how you feel and function.
