A 54‐year‐old patient was studied because of ventricular tachycardia following an inferior myocardial infarction. During one episode of non‐sustained ventricular tachycardia a 9:4 alternating ventriculo‐atrial Wenckebach block was noted. This was based upon a 2:1 block between the ventricles and the bundle of His and a 5:4 Wenckebach block between the bundle of His and the atria. Our study shows that alternate Wenckebach periods during ventriculo‐atrial conduction may be caused by two or more levels of block in the ventriculo‐atrial conduction system.
