Figure 5: The 12-lead electrocardiogram (ECG) showing a regular narrow QRS tachycardia with a rapid ventricular rate of 187 bpm with long RP interval and abnormal peaked P wave morphology. The P waves were biphasic in V1 and positive in leads II, III and aVF suggestive of ectopic atrial tachycardia (EAT) of crista terminalis origin
