Modified lead V5. 70 year old man with ischæmic and peripheral vascular disease, fitted with a temporary pacemaker following cardioversion from atrial tachycardia with block. An episode of bigeminy was interpreted (incorrectly, by myself) as escape-capture bigeminy and the pacemaker slowed down in order to prove it. The correct diagnosis was revealed.
