Aims Endocardial left ventricular (LV) pacing for Cardiac Resynchronization Therapy has
been proposed as an alternative to conventional LV lead placement via the coronary sinus …

Background Implantation of a left ventricular (LV) lead fails in 5% to 10% of patients in whom
cardiac resynchronization therapy (CRT) is attempted. Alternatives for delivery of CRT are …

慢性心力衰竭(CHF) 是一种复杂的临床症候群, 是各类心脏病的严重阶段或终末期表现,
发生率高, 预后差, 5 年存活率与恶性肿瘤相似. 长期以来, 对心力衰竭(HF) …

Several decades of work over the course of the twentieth century led to an expanded
understanding of cardiac mechanical function and the relationship between electrical …

Objectives: Describe an alternative to conventional LV lead placement. Background:
Conventional left ventricular (LV) lead placement is not always possible due to anatomic …

Delivery of leads to the His bundle pacing region is most commonly performed with non-
deflectable or deflectable sheaths and a His lead with an exposed helix. We present a …

To date, several techniques for transseptal left ventricular (LV) endocardial pacing for
cardiac resynchronization therapy (CRT) have been proposed in patients for whom routine …

This chapter discusses different imaging techniques that are increasingly being used in
patients with arrhythmias and in cardiac electrophysiology, the latter comprising ablation …

Background: Implantation of a left ventricular (LV) lead fails in 5-10% of cases in which
cardiac resynchronisation therapy (CRT) is attempted. Alternatives for delivery of CRT are …
