Single-lead VDDR pacing incorporating a mode-switching option is useful in patients with high degree AV block and paroxysmal atrial fibrillation, since it provides atrial synchronous ventricular pacing in more than two-thirds of follow-up time. In a subgroup of patients, a progressive increase of...
Atrial flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium

We describe a case of paroxysmal precipitated by, and dependent on, the presence of atrial flutter. Concealed conduction of atrial impulses to the AV node is the likely cause of this form of . The transient , related, of a longitudinal and transverse dissociation of the AV node, increased ...
Mapping has yielded ablation success rates above 90% for a variety of atrial arrhythmias including atrial tachycardia, AV Node reentry tachycardia, AV reentry tachycardia and atrial flutter [228]. The mainstay of ablation therapy for AF is electrical isolation of the pulmonary veins b...

In order to study the latent atrioventricular block(LAVB)in patients with sicksinus syndrome(SSS),transesophageal atrial incremental pacing(TEAP)was per-formed on 54 patients with SSS whose atrioventricular conduction was normal inelectrocardiogram before pacing.The incidence of LAVB was 96% in patient...
Eight years ago the patient presented with a more profound episode of lightheadedness and had a syncopal episode while in the emergency room. The cardiac monitor revealed paroxysmal high-grade atrioventricular (AV) block. She then underwent implantation of a dual-chamber pacemaker, and her symptoms...

Permanent pervenous atrial sensing and pacing with a new J-shaped lead. We have developed a new J-shaped lead for atrial pacing. The lead has rubber tines which become entangled in the trabeculae and thereby anchor the lead fir... Nicholas P.D. Smyth,Paul Citron,John M. Keshishian,......
