Figure 2: (a and b) Adenosine given during the tachycardia, resulting in transient slowing of the heart rate from 250 bpm to 187 bpm followed by reappearance of the tachycardia. (c) Electrocardiogram during the time of bradycardia following administration of intravenous digoxin showing multiple P waves with periods of flat isoelectric line confirming ectopic atrial tachycardia. (Ectopic P waves marked in red arrows)
