Quizplus · Accepted Answer

A severe cardiac arrhythmia in which contractions are rapid, uncoordinated, and ineffective is called fibrillation. Cardiopulmonary resuscitation (A) is a lifesaving technique used in emergency situations to help someone whose breathing or heartbeat has stopped. Catheterization (B) is a medical procedure in which a thin tube called a catheter is inserted into a body part to diagnose or treat a condition. Coronary heart disease (C) is a condition in which plaque builds up in the arteries that supply blood to the heart, causing them to narrow and reducing blood flow to the heart.
