Demand pacemaker slowing: a simple bedside technique.
We present a simple noninvasive bedside technique to slow gradually any R-wave inhibited ventricular demand pacemaker up to one-half its original rate for indefinite periods of time. Gradual pacemaker slowing allows accurate diagnostic observations and therapeutic interventions in pacemaker-induced arrhythmias and may possibly be used in the management of unstable angina in patients with ventricular demand pacemakers.
