The 11th World Survey of Cardiac Pacing and Implantable Cardioverter‐Defibrillators: Calendar Year 2009–A World Society of Arrhythmia's Project

Abstract

A worldwide cardiac pacing and implantable cardioverter-defibrillator (ICD) survey was undertaken for calendar year 2009 and compared to a similar survey conducted in 2005. There were contributions from 61 countries: 25 from Europe, 20 from the Asia Pacific region, seven from the Middle East and Africa, and nine from the Americas. The 2009 survey involved 1,002,664 pacemakers, with 737,840 new implants and 264,824 replacements. The United States of America (USA) had the largest number of cardiac pacemaker implants (225,567) and Germany the highest new implants per million population (927). Virtually all countries showed increases in implant numbers over the 4 years between surveys. High-degree atrioventricular block and sick sinus syndrome remain the major indications for implantation of a cardiac pacemaker. There remains a high percentage of VVI(R) pacing in the developing countries, although compared to the 2005 survey, virtually all countries had increased the percentage of DDDR implants. Pacing leads were predominantly transvenous, bipolar, and active fixation. The survey also involved 328,027 ICDs, with 222,407 new implants and 105,620 replacements. Virtually all countries surveyed showed a significant rise in the use of ICDs with the largest implanter being the USA (133,262) with 434 new implants per million population. This was the largest pacing and ICD survey ever performed, because of mainly a group of loyal enthusiastic survey coordinators. It encompasses more than 80% of all the pacemakers and ICDs implanted worldwide during 2009.

G protein-gated I KACh channels as therapeutic targets for treatment of sick sinus syndrome and heart block

“…Symptomatic SSS requires the implantation of an electronic pacemaker. SSS accounts for about half of all pacemaker implantations in the United States (5,6). The incidence of SSS has been forecasted to increase during the next 50 y, particularly in the elder population (7).…”

D Tipo Asmenybių Su Implantuotu Elektrokardiostimuliatoriumi Gyvenimo Kokybės Aspektai

“…Europos širdies ritmo asociacija nustatė vis didėjantį elektrokardiostimuliatorių (EKS) implantavimo populiarumą daugelyje Europos šalių ir JAV [1]. Pagrindinis EKS implantavimo tikslas -sustabdyti širdies nepakankamumo progresavimą, kairiojo skilvelio didėjimą ir jo formos pokyčius, pagerinti širdies susitraukimų pajėgumą.…”

Three-Dimensional Carbon Nanotube Electrodes for Extracellular Recording of Cardiac Myocytes

“…According to Mond and Proclemer [17], more than 1,000,000 patients worldwide had a cardiac pacemaker implanted in their body by December 2009, with the number growing annually. However, good electrical contact between cardiac cells and electrodes is not only vital for implants; electrophysiology with cardiac cell cultures has also recently become popular in the field of drug research.…”
