Implication
May warrant high-sensitivity settings in severe myocardial disease; leaves open optimal programming in prospective studies.
Structured PICO
P
Population
n=4 patients with coronary heart disease and cardiomyopathies who experienced demand failures during permanent cardiac pacing
I
Intervention
In vivo and in vitro analyses of the pacemaker system
O
Outcome
Electrogram characteristics (amplitudes and maximum derivatives) and causes of pacemaker demand failure
In patients with severe myocardial disease, low electrogram amplitudes can cause pacemaker demand failure, suggesting a need for high sensitivity or programmable pulse generators.
