During the average human lifespan, the heart beats more than 2.5 billion times, but for open-heart surgery, it must be temporarily arrested. The primary drug used to stop the heart during open-heart surgery is a high concentration of **potassium chloride**, delivered as part of a specialized solution known as cardioplegia. This solution induces a controlled, temporary cardiac arrest to provide a motionless, bloodless surgical field, while also protecting the heart muscle from ischemic damage.

Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery, affecting roughly one-third of patients [1.4.4]. A key strategy in preventing this is prescribing beta blockers, but a frequent question is: **how long do you take beta blockers after open heart surgery?**

Following cardiac surgery, hypertension is a frequent complication that requires careful management [1.3.4]. Several classes of medications are used to control blood pressure, reduce the heart's workload, and prevent complications like heart attacks or strokes [1.2.5, 1.2.1]. This guide explains what blood pressure medication is given after open heart surgery.

Annually, hundreds of thousands of coronary artery bypass graft (CABG) surgeries are performed in the United States. A crucial part of this procedure involves answering the question: **what drug stops the heart during bypass surgery?** The answer lies in a specialized solution called cardioplegia.

While most individuals regain consciousness shortly after their operation, understanding how long does anesthesia stay in your system after open heart surgery is crucial, as residual effects can linger for days, or even a week, before full elimination. The overall recovery from major cardiac surgery, however, extends far beyond the immediate anesthetic effects.
