Abstract

In patients with intact sinus node function and atrioventricular block III(o) VDD pacing with a single pass lead may have advantages compared to conventional DDD systems. The purpose of this study was to evaluate the reliability of a new VDD pacemaker with regard to problems encountered with the implantation and the stability of the atrial sensing potential in the postoperative course. 24 patients (10 male, 14 female; age 61 +/- 17 years) underwent implantation of the Intermedics UNITY 292+07 VDD pacemaker. Patients were analyzed postoperatively with respect to stimulation parameters applied. The mean follow-up was 10+/- 3 months. While early on 23 of 24 patients were paced in a VDD mode, one patient was programmed to the vvi mode due to atrial flutter. One patient died early after aortic valve replacement, while another lost his atrial sensing one month postoperatively. Two patients were reprogrammed to the vvi mode because of atrial arrhythmias. The other 20 patients demonstrated stable atrial sensing potential aside from unchanged ventricular stimulation parameters. No infectious or unchanged ventricular stimulation parameters. No infectious or technical problems were observed. From these results it is concluded that VDD pac...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
