AV Pacemaker: No Ventricular Lead

Report:

Atrial pacemaker rhythm 59/min 2

Right bundle branch block 2

AV interval 0.31” ?no ventricular lead 4

Q waves in 1, aVL, V5-6 – possible old anterolateral infarction 2

Comment:

The diagnosis is suggested by the unusually long AV interval, although, at times, similar intervals are deliberately programmed – See Case 3662. This patient’s ventricular lead retained normal impedance and could not be faulted except for very high threshold; it was changed.
