Apart from the standard 12 leads, additional leads are sometimes useful in the diagnosis of various conditions. These include right sided chest leads, posterior leads and elevated leads. Although ideally these should be recorded by placing electrodes in these locations, they can be derived from the standard leads. Here, right sided (V3R, V4R, V5R and V6R), posterior (V7, V8 and V9) and elevated leads (V1+1, V2+1, V1+2, V2+2) are derived and displayed. See here for more details.

Arrhythmogenic Right Ventricular Cardiomyopathy

The epsilon wave is a small amplitude, high frequency wave seen after the QRS and represents the delayed repolarization of abnormal myocardium. This abnormal depolarization along with repolarization abnormality in the form of T inversion in leads V1 to V4 is typical of ARVC.
