Myopotential Inhibition of VDD pacemaker in unipolar mode
This is a classic recording of myopotential inhibition of a pacemaker. Note the pacemaker that was following the patient's p waves for the first three beats, stops pacing as soon as the baseline records the "buzz" of the pectoral muscle activity. As the pacer stops pacing, the patient's underlying rhythm is seen which appears to be 2:1 Av block.
As the "buzz" disappears normal pacing returns.
