Key result
Horizontal RS-T vectors and V1 depression distinguish acute pericarditis from early repolarization.
Why the study?
Electrocardiographic mimicry between acute pericarditis and early repolarization necessitates differentiation to guide diagnosis and management.
What are the differential electrocardiographic characteristics between acute pericarditis and early repolarization?
Observational (n=96)
What are the differential electrocardiographic characteristics between acute pericarditis and early repolarization?
p-value: p=≤0.01
Specific electrocardiographic features, such as RS-T vector orientation and PR segment deviations, can reliably differentiate acute pericarditis from early repolarization.
These ECG criteria may aid differentiation of pericarditis from early repolarization; leaves open prospective validation before clinical adoption.
Electrocardiographic mimicry necessitates differentiation between acute pericarditis and early repolarization. Among 96 persons, limb-lead RST deviations occurred in all 48 with pericarditis, but only 27 with early repolarization. RS-T vectors (A RS-T) in pericarditis tended to be horizontal (25 patients) and left of the T vector, A T (28 patients); in early repolarization, A RS-T was vertical in 15 subjects and right of A T (20 subjects); P less than or equal to 0.01. RS-T depression in Lead V1 was more common in pericarditis (14 vs. two); isoelectric RS-T in Lead V6 was more common in early repolarization (10 vs. one); P less than or equal to 0.01. PR segment deviations occurred in both limb and precordial leads in pericarditis; in early repolarization they were confined to either lead group. Thus, R-ST deviations in both limb and precordial leads with horizontal A RS-T to left of A T and RS-T depression in Lead V1 favor pericarditis; vertical A RS-T and isoelectric RS-T in Lead V6 favor early repolarization.

David H. Spodick (1976) conducted an observational in Acute pericarditis and early repolarization (n=96). Acute pericarditis vs. Early repolarization was evaluated on Electrocardiographic characteristics including RS-T vectors and deviations (p=≤0.01). Acute pericarditis was characterized by horizontal RS-T vectors left of the T vector and RS-T depression in V1, whereas early repolarization featured vertical RS-T vectors and isoelectric RS-T in V6 (P≤0.01).
