The correct answer is D
Wenckebach phenomenon is a form of incomplete atrio-ventricular heart block in which there is progressive lengthening of conduction time in cardiac tissue with P-R interval increasing until there is not a ventricular response.
This is followed by a conducted beat with a short P-R interval, and then the cycle repeats itself. This occurs frequently after an inferior myocardial infarction and tends to be self-limiting.

Inferior wall MI => increased vagal tone => Bradycardia
Antero septal MI => increased sympathetis tone => increased HR
Harrison's gives it that way
