Introduction Cardiac resynchronization therapy (CRT) with left ventricular (LV)-only pacing has emerged as an alternative to biventricular (Bi-V) pacing used to synchronize ventricular contraction by timing LV pacing with intrinsic right ventricular (RV) conduction. Additionally, RV pacing is minimized, improving device longevity. Despite its benefits, LV pacing may not the best modality for al...

Implantation numbers of conventional antibradycardia pacemakers (PM), implantable cardioverter defibrillators (ICD) and cardiac resynchronisation therapy PMs ICDs (CRT-P D) have shown a minimal increase till 2017. Between 2017–2019 the implantation remained on steady state level, ILR, CRT-D slight increase, moreover ratio CRT-P against has decreased. Year 2020 was special year due to SARS-CoV2 ...

The development of implantable technology for cardiac rhythm management remains one of the seminal achievements of the second half of the 20th century. The modern era of cardiac pacing began in 1958, when Elmqvist and Senning1 implanted the first cardiac pacemaker by thoracotomy in a human, and Furman and Robinson2 implanted the first endocardial lead. The focus of development of cardiac pacing...

Cardiac resynchronization therapy (CRT) can substantially improve dyssynchronous heart failure and reduce mortality. However, about one-third of patients who are implanted, derive no measurable benefit from CRT. Non-response may partly be due to suboptimal activation the left ventricle (LV) caused by electrophysiological heterogeneities. The goal this study is investigate performance a newly de...

Cardiac pacing remains one of the most effective means for preventing torsade de pointes in patients with long QT syndrome (LQTS). However, fatal arrhythmias may occur despite combined therapy with beta blockers and pacing, and it is possible that failure of cardiac pacing for preventing arrhythmias in the long run is related (at least in part) to suboptimal pacemaker programming. Preventing su...

INTRODUCTION AND OBJECTIVES In recent years, implantation of cardiac resynchronization therapy devices has significantly increased. The benefits of this therapy are directly related to the maintenance of continuous biventricular pacing. This study analyzed the incidence, causes, and outcomes of loss of continuous biventricular pacing, and the approach adopted. METHODS We analyzed the clinical...

BACKGROUND The optimal pacing rate during cardiac resynchronization therapy (CRT) is unknown. Therefore, we investigated the impact of changing basal pacing frequencies on autonomic nerve function, cardiopulmonary exercise capacity and self-perceived quality of life (QoL). METHODS Twelve CRT patients with non-ischemic heart failure (NYHA class II-III) were enrolled in a randomized, double-bli...
