Antitachycardia pacing with cardioverter-defibrillator backup for malignant ventricular dysrhythmias.

This article provides a summary of the history of antitachydysrhythmic devices and their current application in patients with ventricular dysrhythmias. Future trends are also discussed, followed by a case study illustrating the nursing care required for a patient with a combination antitachycardia pacemaker and automatic implantable cardioverter-defibrillator for slow ventricular tachycardia. The basic principles provided can be incorporated into the teaching plans of patients with antidysrhythmic devices for malignant ventricular dysrhythmias.

Initial clinical experience with a rate responsive pacemaker.

Prism-CLR is a new single chamber unipolar pace, bipolar or unipolar sense, rate responsive pacemaker that utilizes a closed-loop system based on the analysis of the evoked potential for rate adjustment. It also has an automatic output regulation feature for capture verification and threshold search. Five patients in whom this pacemaker was implanted exhibited an appropriate rate increase with exercise and psychological stress. Automatic output regulation functioned appropriately in three of five patients. Preliminary data suggest that Prism-ClR is an effective pacemaker for patients who may benefit from rate responsive pacing. The automatic output regulation recognition algorithm may need modification in some patients.
