conclusions in this study, sick sinus syndrome and pacemaker mode followed by syncope were independently associated with increased mortality. results survival data were available for 1030 (80%) patients (median age = 71 years [5th to 95th percentile range: 26 - 86 years]) and follow-up was completed for 84.28% of them. according to the results, 56% of the patients had received dual-chamber syst...

a 29-year-old woman was referred to our hospital due to exacerbation in dyspnea on exertion and easy fatigability. a known case of congenitally corrected transposition of the great vessels and congenital complete heart block, she had already received a permanent single-chamber pacemaker. decision was made to implant a biventricular pacemaker for the treatment of the failing heart. excellent cor...

Approximately 3% 11.8% of cases require permanent pacemaker implantation due to atrioventricular block (AVB) after aortic valve replacement (AVR), and determination of conduction disturbances such as left or right bundle branch block by preoperative electrocardiography is correlated with high risk postoperative permanent pacemaker implantation. Intraoperative risk factors include severe calcifi...

Permanent cardiac-pacemaker therapy is widely recognized as beneficial in the treatment of various types of symptomatic bradycardia. However, the seasonal distribution of pacemaker implantation has never been discussed. The purpose of this study was to investigate the seasonal distribution of pacemaker implantation in a large population of patients with symptomatic bradycardia. The study popula...

BACKGROUND Pacemaker dependency (PD) can be defined as the risk of serious injury or death from sudden pacemaker failure, an event more dangerous than progressive rate decrease. The aim of this study was to evaluate the incidence of PD during long-term follow-up after pacing system implantation. METHODS AND RESULTS The study included 3638 patients (mean age 65.3 +/- 10.2 years). Indications f...

OBJECTIVES English springer spaniels (ESS) are one of the most frequently presented breeds for pacemaker implantation in the UK and may do so at an early age. In comparison to dogs of other breeds (non-ESS) presenting for pacemaker implantation, cardiac troponin I (cTnI), the outcome and survival of ESS were investigated. METHODS Case records of dogs receiving pacemaker implantation were retr...

Temporary pacemakers are classically indicated for severe bradydysrhythmia, especially when the clinical settings require prompt intervention. Implantation of a temporary pacemaker is not a benign procedure since it may be associated with serious adverse events such as infection, cardiac perforation, and lead dislodgment. Accordingly, we recommend, when the clinical condition allows, to proceed...

INTRODUCTION AND OBJECTIVES Although changes in atrioventricular conduction frequently occur after percutaneous implantation of an aortic valve prosthesis, little is known about the mechanisms involved or how these changes progress. We investigated ECG abnormalities and predictors of pacemaker need after percutaneous implantation of the CoreValve® aortic valve prosthesis. METHODS Between Apri...

Background and aim: Permanent cardiac pacing is the most efficient treatment for patients with symptomatic bradycardia and high-degree atrioventricular (AV) block. For effective pacing, sensing and pacemaker battery longevity; ventricular pacing threshold (VPT) levels, lead impedance levels and Rwave amplitude levels must be desirable. We aimed to search the association between elevated serum t...

Method From 1989 to 2013, 44 patients (15 neonates) underwent pacemaker implantation within the first year of life. The mean age and weight were 101.2 ± 97.2 days and 4.8 ± 1.8kg at the time of pacemaker implantation. The Indication for pacemaker implantation were postoperative atrioventricular block in 23, congenital atrioventricular block in 16, sinus node dysfunction in 4, and myocarditis in...
