Abstract
OBJECTIVE:TO summarize the newest clinical application of permanent cardiac pacemaker, and introduce the relationship between the therapy efficacy and mechanism.DATA SOURCES: Related papers were searched in Pubmed from January 2000 to December 2006 with the terms of "pacemaker,application",and the language of paper was limited to English,at the same time,related papers were searched in WangFang Database with the same terms and the language of paper was limited to Chinese.STUDY SELECTION:The papers relevant to the newest large-scale clinical trial about the cardiac pacemaker were primarily collected.Exclusion criteria:repetitive studies.DATA EXTRACTION:A total of 203 pieces of papers related to the newest clinical application of cardiac pacemaker were collected,among which,30 pieces accorded with the inclusion criteria.DATA SYNTHESIS:The pacemaker can simulate the normal myocardium cell's function pacing and conducting the rhythm. Consequently it can substitute the abnormal myocardium cell to ensure the sequence and completeness of the cardiac pacing and conducting system,the natural electrophysiological activity,and the efficiency of the cardiac ejection and blood supply.The clinical application is not only for single bradycardia, but also for cardiac electric failure, cardiac electric turbulence,and some heart diseases without cardiac electric abnormity.With pacemaker miniaturization,digital signal processing, improved diagnostics and endocardial electrograms, modern pacemakers are able to offer a sophisticated therapeutic and diagnostic platform for the patients with refractory symptoms.CONCLUSION:The pacemaker can simulate the normal myocardium cell's function pacing and conducting the rhythm.It therapy for congenital heart disease.关键词
