Single-lead VDD pacing: long-term experience with four different systems

American Heart Journal

Abstract

Previous multicenter studies have shown that single-lead VDD pacing systems provide satisfactory atrial-triggered ventricular pacing at middle term for treatment of atrioventricular block without sinus dysfunction. However, we lack data on long-term results obtained with different VDD systems implanted in a large number of patients from a single center. One hundred fifty patients (76 +/- 11 years) with second- or third-degree atrioventricular block (n = 147) or symptomatic hypertrophic cardiomyopathy (n = 3) without sinus dysfunction were paced with four different VDD pacing systems able to sense the atrium and to pace the ventricle. Atrioventricular synchronization was assessed during follow-up by ECG and Holter monitoring. Mean value of the atrial electrogram during implantation was 2.01 +/- 0.94 mV without any differences among the four systems. With a mean follow-up of 24 +/- 11 months, 95% of patients remain paced in VDD mode, whereas 5% have been reprogrammed in VVI or VVIR mode for permanent atrial fibrillation or loss of atrial sensing; 96% of patients with sinus atrium have atrioventricular synchronization >90% and 94% of patients have >95%, without significant difference between the four systems used. These different ...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.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. 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.
