Longevity in patients with high degree atrioventricular block paced in the atrial synchronous or the fixed rate ventricular inhibited mode.
Survival in patients paced for high degree AV block has been demonstrated to be influenced by underlying cardiac disease in particular congestive heart failure. One previous study has suggested that dual chamber pacing may improve the vital prognosis for such patients. To investigate (his, 74 patien...

One previous study has suggested that dual chamber pacing may improve the vital prognosis for such patients. To investigate (his, 74 patients treated with rate adaptive atrial synchronous (VDD) and 74 patients treated with VVI pacemakers for high degree AV block, were retrospectively studied for a mean of 5.4 years by life-table analysis. The two groups had an equal distribution of age, sex, date of pacemaker implantation, and concomitant cardiovascular diseases. Total mortality and estimated survival did not differ between (he two groups. The estimated survival in the VDD group at 1, 3, and 5 years for patients without and with congestive heart failure was 94%, 86% and 78%, and 92%, 83% and 72%, respectively. In the VVI group the corresponding values were 95%, 90%, and 83% for patients without congestive heart failure and 82%, 64%, and 47% for those with congestive heart failure (P = 0.008). Compared to the expected survival rate of the general Swedish population, only the VVI group with congestive heart failure, had an excess mortality (P = 0.007). Patients with high degree AV block have a fairly normal vital prognosis irrespective of pacing mode. The prognosis for patients with congestive heart failure was negatively affected by VVI pacing. Thus, for patients with congestive heart failure the choice of pacing mode is of vital importance, whereas for patients without congestive heart failure, other factors such as feeling of well-being and exercise capacity should decide the final choice of pacing mode. pubtype: Academic Journal doctype: research Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
