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 a device called Bispectral Index (BIS) monitoring—which measures your level of sedation through your forehead—helps doctors manage anesthesia better during electrical cardioversion, a procedure to restore normal heart rhythm in patients with atrial fibrillation. Half the patients will receive sedation guided by this BIS monitor, while the other half will receive sedation guided by traditional clinical signs. The goal is to see if the BIS monitor helps prevent too much sedation (which can cause breathing problems) or too little sedation (which can cause discomfort).
During electrical cardioversion, doctors need to keep patients deeply asleep, but finding the right balance is tricky—too much medication can harm your breathing and heart stability, while too little can cause pain and awareness. This trial exists to find out whether using real-time brain monitoring gives doctors better information to use exactly the right amount of medication.

You will come to the hospital for your scheduled electrical cardioversion procedure. Before the procedure, you'll receive intravenous sedation (first fentanyl, then propofol) to help you sleep. If you're in the BIS-monitored group, doctors will watch a special brain-monitoring device to guide how much medication you receive, aiming for a specific sedation level. If you're in the standard group, doctors will use their clinical judgment based on traditional signs (like whether you're asleep). The entire procedure, including recovery, typically takes a few hours. You'll be monitored closely throughout and will need someone to drive you home afterward.
