Orthodromic Atrioventricular Reentrant Tachycardia Presenting To The Komfo Anokye Teaching Hospital, Kumasi, Ghana

In Wolf-Parkinson-White (WPW) pattern pre-excitation, an accessory pathway known as the bundle of Kent conducts electric impulses directly from the atrial to the ventricles. Patients with WPW pre-excitation are therefore predisposed to paroxysmal supraventricular tachycardia (PSVT). The PSVT can be a narrow QRS complex tachycardia or broad QRS complex tachycardia. This presentation is on a patient with WPW pattern pre-excitation presenting as a narrow QRS complex tachycardia.
