Why the study?
What is the cause of pacemaker failure in dogs with induced AV block and electrodes implanted in normal vs scar tissue?
Population
Dogs with induced atrioventricular conduction blocks
Comparison
Ventricular stimulation via electrodes implanted… vs Ventricular stimulation via electrodes implanted…
Design
Preclinical
Key result
Failure of ventricular stimulation in dogs with induced heart block was due to wire breakage or loss of contact, not excessive scarring, despite scar tissue requiring more power.

In a canine model of AV block, pacemaker failure was caused by mechanical issues (wire breakage or loss of contact) rather than excessive scarring.

In a canine model of AV block, pacemaker failure was caused by mechanical issues (wire breakage or loss of contact) rather than excessive scarring.
Albert et al. (1962) studied Atrioventricular conduction blocks. Ventricular stimulation via electrodes implanted into scar tissue vs. Electrodes implanted into normal myocardium was evaluated on Failure of stimulation. Failure of ventricular stimulation in dogs with induced heart block was due to wire breakage or loss of contact, not excessive scarring, despite scar tissue requiring more power.
