Is PQ-segment depression associated with the occurrence of atrial fibrillation in patients with infarction-associated pericarditis?
In patients with infarction-associated pericarditis, PQ-segment depression is a useful clinical sign indicating atrial involvement and risk for atrial fibrillation.
Among patients with infarction-associated pericarditis, those with PQ-segment depression represent atrial involvement associated with extensive myocardial damage and hence, PQ-segment depression is one of the clinical signs related to the occurrence of atrial fibrillation in acute Q-wave myocardial infarction.
