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.

Idioventricular Rhythm

A wide QRS rhythm is seen when the sinus rate slows and is then suppressed when the sinus rhythm accelerates again. The wide QRS complexes are not preceded by P waves and there are fusion beats confirming a ventricular origin. Due to the rate being slower than 100 bpm, this is called an idioventricular rhythm.
