Why the study?
Does varying pulse duration affect the minimum energy required for cardiac pacing in patients undergoing permanent pacemaker implantation?
Population

Lower threshold energies at longer durations may guide output programming; hypothesis-generating and requires randomized confirmation before practice change.
Does varying pulse duration affect the minimum energy required for cardiac pacing in patients undergoing permanent pacemaker implantation?
Significant energy savings can be achieved by programming pacemakers to optimum output by reducing voltage/current rather than reducing pulse duration.
HILL et al. (1988) studied this question.
