Question

PAT stands for paroxysmal atrial tachycardia, which is a type of abnormal heart rhythm that originates in the upper chambers of the heart and results in episodes of rapid, regular heartbeats that begin and end abruptly. A-fib (atrial fibrillation) is also an abnormal heart rhythm that originates in the upper chambers of the heart, but it is characterized by a chaotic and irregular heartbeat. PVC (premature ventricular contraction) and V-fib (ventricular fibrillation) are abnormal rhythms that originate in the lower chambers of the heart. CAD (coronary artery disease) is not related to abnormal heart rhythms, but rather refers to a condition in which the arteries that supply blood to the heart become narrowed or blocked.
