Quizplus · Accepted Answer

Cardioplegia is a technique used in cardiac surgery to intentionally stop or arrest the heart for a controlled period. This is achieved by introducing a solution containing potassium ions into the heart's circulation, which inhibits the heart's electrical conduction system, leading to cessation of the heart's contractions. This allows surgeons to perform procedures on a still heart, reducing the risk of damage and improving surgical outcomes.
