Key result
Electrocardiographic evaluation of patients with acute pericarditis revealed transient gross deviations of P-R segments in 82% of cases, consistent with subepicardial atrial injury.
Observational (n=50)
P-R segment deviations are highly prevalent (82%) in acute pericarditis, representing subepicardial atrial injury that can sometimes mimic ST-segment elevation.

P-R deviations may mimic ST elevation in pericarditis; leaves open whether ECG criteria require revision in prospective cohorts.
David H. Spodick (1973) conducted an observational in Acute pericarditis (n=50). Acute pericarditis was evaluated on Transient gross deviations of P-R segments. Electrocardiographic evaluation of patients with acute pericarditis revealed transient gross deviations of P-R segments in 82% of cases, consistent with subepicardial atrial injury.
