Pharmacological- and electrical-first cardioversion worked similarly well for treating acute atrial fibrillation (Afib) in the emergency department, according to the Canadian RAFF2 trial. The 204 ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...

The drug-shock strategy was more effective for patients experiencing atrial fibrillation for the first time and for patients younger than 70 years, the researchers said. Both the anti-arrhythmia drug ...

Cardioversion is a medical procedure to correct a heartbeat that is irregular or too fast. It can involve risks and side effects but is generally safe and effective. Doctors primarily use ...

Pharmacologic cardioversion followed by electrical cardioversion and electrical cardioversion only were found to be safe and effective in patients presenting to the emergency department with recent ...
