We have a homework assignment where we have to list 4 nursing interventions if a pacemaker is not capturing. I understand a failure to capture means that the pacemaker is not providing enough of a charge to produce atrial or ventricular contraction, and that this can lead to bradycardia or tachycardia. I'm just not sure what the nursing interventions are if this occurs. Answers would be helpful, or even just sources that can point me in the right direction. Thanks!
