OBJECTIVETo observe the results of remote home monitoring for cardiac implantable electronic devices (CIED).

METHODSFrom November 2009 to July 2014, 37 patients implanted with home monitoring system CIED were enrolled, and 31 cases were implanted with dual chamber pacemakers, 2 with cardiac resynchronization therapy(CRT) and 4 with implantable cardioverter defibrillator (ICD). All patients received clinical routine follow-up.Data was automatic transmitted daily by remote home monitoring system, while special alarm events were transmitted at any time.The success rate of data transmission, abnormal events monitoring and pacing parameter changes were analyzed.

RESULTSA total of 37 patients (24 males, mean age (70.0±9.6) years) were enrolled.Average follow-up time was (902±404) days.Success rate of data transmission was 97.6% (32 574), failed data transmission rate was 2.4% (801). Ninth-nine alerts were transmitted from 28 patients (75.7%), including 80 (80.8%) disease-related alerts and 19 (19.2%) system-related alerts.Average detection time of atrial fibrillation by remote home monitoring system to last clinical routine follow-up was 62 (19-120) days.There was no significant change in ventricular threshold, atrial and ventricle sensing during acute, subacute and chronic phases post the application of the steroid-eluting leads(all P>0.05).

CONCLUSIONSThe success rate of data transmission for CIED with remote home monitoring system is efficient, abnormal events can be timely detected.Meanwhile, remote home monitoring system also verified the stability of pacing parameters during acute, subacute and chronic phases post the application of the steroid-eluting leads.
