Figure 2: The electrocardiographic monitor (25mm/s) shows the alternate polymorphic premature ventricular contractions with an episode of atrial tachycardia followed by the polymorphic ventricular tachycardia; heart rate of 68bpm on cardiac monitoring corresponds to the low amplitude premature ventricular contractions that are not counted as heartbeats by the monitor
