Webb14 apr. 2024 · Summary. J point is the point of junction between the end of the QRS complex and the beginning of the ST-segment. Normally it is over the isoelectric line of the electrocardiogram. However, it can be elevated by as much as 2 mm above the base line in leads V 2 and V 3 in persons without any structural heart disease. Webb1 dec. 2024 · The ECG shows ventricular pacing in complexes 1, 4, 5, 8, 9, and 10, which exhibit the same QRS morphology ( Fig. 2 ). However, complexes 3 and 7 have a different morphology. Complexes 2 and 6 result from ventricular pacing after a premature atrial complex (PAC). The R-R intervals after beats 2 and 6 are much longer than those in the …
