SpletAlthough the upper limits of the S wave amplitude in leads V1, V 2, and V 3 have been given as 1.8, 2.6, and 2.1 mV, respectively, 31 an amplitude of 3.0 mV is recorded occasionally in healthy individuals. 36 An S wave is often absent in leads V 5 and V 6. An S wave of less than 0.3 mV in lead V 1 is considered abnormally small. SpletS-wave duration is greater than R-wave duration, or S-wave duration is greater than 40 ms in V6 and I. ST-T changes: V1-V2 shows downsloping ST-segments and inverted T-waves. Leads V5, V6, I and aVL shows positive T-waves. If the QRS duration is ≥0,110 seconds but <0,12 seconds, the right bundle branch block is said to be incomplete. preethi john ucl

SpletV1 is at the top right of the heart (over the right fourth intercostal space, or about the location of the right atrium). From the point of view of V1, ventricular depolarization is a wave of electricity moving away, since ventricles point down and to the left.

The ventricular septum is relatively small, which is why V1 displays a small positive wave (r-wave) and V5 displays a small negative wave (q-wave). Thus, it is the same electrical vector that results in an r-wave in V1 and q-wave in V5. Prikaži več Naming of the waves in the QRS complex is easy but frequently misunderstood.
