A noninvasive, effective approach for immediate and painless heart pacing would have invaluable implications in several clinical scenarios. Here we present a novel strategy that utilizes the well-known mechano-electric feedback of the heart to evoke cardiac pacing, while relying on magnetic microparticles as leadless mechanical stimulators. We demonstrate that after localizing intravenously-inj...

AIMS Pacing from multiple sites in the left ventricle (LV) may bring about further resynchronization of the diseased heart compared with biventricular (BiV) pacing. We compared acute haemodynamic response (LV dP/dtmax) of multisite and BiV pacing using a quadripolar LV lead. METHODS AND RESULTS In 21 patients receiving cardiac resynchronization therapy, a quadripolar LV lead and conventional ...

Experience of endocardial pacing in eighty-two patients with atrioventricular block after myocardial infarction is described. A unipolar pacing wire was passed into an antecubital fossa vein and passed into the right atrium and wedged into the apex of the right ventricle under radiological control using an image intensifier. All patients were attached to an external demand unit set at 60/min wh...

Bistability in periodically paced cardiac tissue is relevant to cardiac arrhythmias and its control. In the present paper, one-dimensional tissue of the phase I Luo-Rudy model is numerically investigated. The effects of various parameters of pacing signals on bistability width are studied. The following conclusions are obtained: (i) Pacing can be classified into two types: pulsatile and sinusoi...

ranscutaneous (external) temporary pacing ('ITP) was originally developed in the T 1950s. Although unquestionably effective, it caused extensive contraction of the chest wall muscles and diaphragm and was therefore largely abandoned with the advent of temporary transvenous pacing. Recent improvements in techniques have led to improved patient tolerance and a rekindled interest in TTP, especiall...

We report a case of successful transcutaneous external pacing for out of hospital cardiac arrest causing asystole.

A 29 year old woman with a background of poorly controlled iabetes was admitted to our hospital in cardiogenic shock due o acute inferior myocardial infarction and complete heart block. ecycled external electrodes (“stat.padz®”) were placed to the right f the upper sternal border below the clavicle and to the left of he nipple with the centre of the electrode in the mid-axillary line. xternal p...

Introduction Transcatheter implantation of balloon expandable valves in high-risk patients with degenerated tricuspid bioprostheses has been reported since 2010 [1, 2]. Although there have been cases where the SAPIEN valve was implanted in the tricuspid position without rapid pacing [3, 4], invasive rapid ventricular pacing is usually applied during valve deployment. We present a case report do...
