Do cardioversions for atrial fib weaken the heart?

Cardioversions are generally considered safe and do not typically weaken the heart. Cardioversions involve delivering a controlled electrical shock to the heart to restore normal heart rhythm in individuals with certain types of arrhythmias, commonly atrial fibrillation. While cardioversions can cause temporary discomfort or minor side effects, long-term risks, including significant heart weakening, are rare. However, the success and safety of any medical procedure depend on individual circumstances and underlying health conditions. It's crucial to discuss the potential risks and benefits of cardioversion with a medical professional before undertaking the procedure.
