WebFigure 4. Multifocal atrial tachycardia. Multifocal atrial tachycardia is an unusual variant of ectopic atrial tachycardia. As seen in Figure 4, it is characterized by an irregular rhythm with clearly visible P-waves (on the contrary to atrial fibrillation) but the P-wave morphology varies from one beat to another.This is explained by the fact that there are multiple … WebA biphasic T-wave has a positive and a negative deflection. It should be noted that the term "biphasic" is unfortunate because (i) biphasic T-waves carry no particular significance and (ii) a T-wave is classified as positive …
