Why do patients with an av block 3rd degree have a negative t wave on bipolar ekg?

Abnormal Rhythm: 3rd degree av block = complete av block... Meaning the upper chambers are not in synch with the ventricles. The ventricular depolarization is abnormal, the t-wave which are basically the re-set waves, will be abnormal. Many times the t wave is flipped. This isn't unexpected. The ventricular beats will be junctional or ventricular escape beats and the t-waves will vary.

Av block: Normally t Waves should not be any different if it's a junctional rhythm.
