Electrocardiography showing regular rhythm at a rate of 55 bpm with normal QRS complex duration and morphology. AS atrial rate (70 bpm) was faster than the ventricular rate (55 bpm), and PP interval was constant with no relationship between the P waves and QRS, demonstrating atrioventricular dissociationBack to article page
