Other Rhythms

Other rhythms not previously listed include a lack of rhyhtm (asystole), multiple or changing rhythms. In general, rhythms are often divided into narrow and wide based on the size of the QRS complexes. Narrow rhythms are always supraventricular rhythms. Wide complex rhythms can be either ventricular in origin, or supraventricular with an additional conduction delay through the ventricles.
