The mean QRS axis is shifted to the right, which is right axis deviation (RAD), and this should make one think first of RVH. After the RAD, this tracing shows all other diagnostic features of RVH, ...

Objective: Precordial ECGs reveal significant intrasubject variability due to the inexact employment of the recommended V 1-V 6 chest landmarks. Also, as per the Einthoven law, the six limb leads can ...

The Brugada criteria/algorithm is below: 1. Do you see concordance present in the precordial leads (leads V1-V6)? Sometimes explained as the absence of an RS complex, concordance is diagnostic of ...

TO THOSE with extensive electrocardiographic experience, especially if it includes a large proportion of young adults, the finding of the pattern of a short PR interval and a prolonged QRS complex ...

An Apple watch can obtain a multilead ECG comparable to that of a conventional 12-lead readout, preliminary research suggests. When compared with a conventional ECG, the Apple Watch ECG showed ...
