Abstract
The primary objective of pacemaker implantation is not only to prolong life by preventing asystole and Adams-Stokes attacks but also to maintain quality of life. Atrioventricular synchrony is not only important with respect to symptoms such as a general feeling of well being, fatigue, light headedness, dizziness or even syncope (due to the loss of the atrial kick) [1, 2], but also because the long term absence of AV synchrony increases the incidence of atrial fibrillation and stroke and may reduce the patients life expectancy [3–6]. Evidence of the relation between atrial fibrillation, congestive heart failure and thrombo-embolism to VVI(R) pacing as opposed to AAI(R) or DDD(R) in sick sinus syndrome patients is convincing. The concept that single chamber ventricular pacemakers with adaptive rate functions are equivalent to the dual chamber pacemaker cannot be supported as a rule [1].
