LV Hypertrophy [Sokolow; SV1 + (RV5 or RV6) > 35mm) or RI + SIII > 25mm]?
No
RV Hypertrophy [R/S ratio V5 or V6 < 1 or R/S ratio V1 > 1 or S1S2S3 pattern]?
No
ST segments:
Duration = 120 ms
Morphology = sagging depression V2, V3
T waves:
Duration = 160 ms
Morphology = inversion aVL, V1-3
QT interval:
QT duration = 410 ms
QTc duration = 510 ms
Additional comments:
Wandering baseline first 5 complexes
Interpretation: Incomplete RBBB. Left axis deviation: almost bifascicular block. The rhythm cannot be determined with certainty; it is unclear if there are any P waves, although the PR interval could possibly be prolonged > 200 ms, making this almost trifascicular block.
