The bradycardia-tachycardia syndrome was treated with pacemaker implantation and drugs in 28 patients. All patients survived pacemaker implantation and 26 of 28 patients experienced good control of their arrhythmias. Nineteen patients survived for more than one year (group 1); nine patients survived for less than one year (group 2), including two patients whose arrhythmias were not well control...

A 55-year-old female patient with earlier diagnosis of cardiac cirrhosis and mitral valve implantation was admitted with complaints of weakness and dizziness. She had undergone VVIR pacemaker implantation 9 years earlier due to low ventricular rate atrial fibrillation and had generator replacement procedure 3 months previously. Electrocardiogram indicated pacemaker dysfunction due to failure to...

A 78-year-old woman presented to our emergency room because of complete atrioventricular block. The patient experienced significant psychophysical stress during pacemaker implantation due to fear of operation. Acute lung edema occurred four hours after permanent pacemaker implantation. Coronary angiography showed no significant coronary artery stenosis and left ventriculography revealed typical...

BACKGROUND We investigated the clinical course of complete right bundle branch block (RBBB) or RBBB with axis deviation (AD) in terms of subsequent pacemaker implantation for high-degree atrioventricular (AV) block or sick sinus syndrome (SSS). METHODS AND RESULTS Among the 16,170 atomic-bomb survivors in our biennial health examination between July 1967 and December 2010, we detected 520 new...

BACKGROUND Few studies have characterized the surgical outcomes following epicardial pacemaker implantation in neonates with congenital complete atrioventricular block (CCAVB). OBJECTIVE This study sought to assess the long-term outcomes of a minimally invasive epicardial approach using a subxiphoid access for pacemaker implantation in neonates. METHODS Between July 2002 and February 2015, ...

One hundred thirty patients have had 244 pacemakers of five types implanted at Presbyterian-St. Luke’s Hospital in the past eight years. There has been I 0.50 probabilIty of successful unit function at only 12 months with epicardial units. All transvenous units used have had a 0.50 probabilIty of unit success at more than 17 months. This fact, combined with the lower frequency of early death wi...

This report describes perforation of the aorta related to the implantation of an active-fixation atrial pacing lead, a previously undocumented complication of pacemaker implantation. The complication was related to excessive tissue penetration by the screw at the tip of the lead or perforation of the lead body by the positioning stylet during manipulation whereupon the stylet traversed the atri...

Advances in pacemaker technology over the last 25 years have made cardiac pacing in infants and children a safe and practical therapy. Some of the technical challenges encountered with the first permanent pacemaker implantation in children during the early 1960s have been solved with miniaturized generators, lithium batteries, noninvasive programmability, and improved placement techniques. This...

A patient is described who has 6 months of progressive dyspnea and peripheral edema for 4 years following implantation of an endovascular pacemaker, which was complicated by a large hemorrhagic pericardial effusion. Evaluation was consistent with constrictive pericarditis, which is an extremely unusual complication of pacemaker implantation.

UNLABELLED Aberrant waveform during artificial pacing increases secretion of natriuretic peptides, mainly B-type natriuretic peptide (BNP). The aim of the study was to investigate whether renal function is modified through increased BNP secretion during artificial pacing. MATERIAL AND METHODS A total of 117 patients with pacemaker implanted were included (pacing mode: AAI/R - 21, DDD/R - 59, ...
