In this tutorial, we have selected some samples of common arrhythmias and in each case the actual clinical history is followed by a discussion of the electrocardiogram. These tracings are shown so that the viewer can have a chance to form an opinion before a discussion by the expert.

Many examples of arrhythmias together with their appropriate treatment are shown and we have endeavoured to present the common varieties usually encountered in clinical practice.
