A New Paradigm for Physiologic Ventricular Pacing

A new paradigm for physiologic ventricular pacing.

Clinical trials in patients with pacemakers for sinus node dysfunction or atrioventricular block (AVB) and implantable cardioverter-defibrillators provide increasing evidence showing that desynchronization of ventricular electrical activation and contraction, induced by conventional right ventricular apex (RVA) pacing, is a serious threat for long-term cardiac morbidity and mortality. The risk ...

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

Physiologic pacing: where pacing mode selection reflects the indication.

Results of recent trials suggest that in patients with left ventricular dysfunction, interventricular synchrony is possibly more important than atrioventricular synchrony. In patients with AV block and conduction system disease, alternatives to right ventricular apical pacing are therefore needed.

Who Needs Physiologic Pacing and Why?

Various pacing technologies have been developed during the past 50 years since the first pacemaker was implanted in 1958. Dual-chamber pacing, rate responsiveness, programmable and rate-responsive atrioventricular (AV) intervals, alternative-site pa0cing, and new multichamber pacing devices are all attempts to mimic normal cardiac physiology as much as feasible. The categories of alternative-si...
