Objectives: To evaluate the benefit of Home monitoring (HM) system in patients with implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D). Methods: Twenty-three patients undergoing implantation of ICD or CRT-D with HM in our hospital were enrolled from January 2011 to August 2013. Data of patients were transmitted by Home monitoring system. Data automatically collected on a daily basis and alerts by HM were analyzed. Early detection and intervention effect of Home monitoring system included arrhythmias or heart failure to clinical events and system related events. Results: The mean follow-up duration was 452.1+/-262.2 days, a total of 1991 remote transmissions were received. Among these transmissions, 1481 abnormal events were reported and 96.4% of events were clinical-related, and 1.5% were system-related, no transmissions by 2.1%. Most of the system-related events were abnormal sensing, and one loose electrode placement of left ventricular was detected. Clinical events included 84.7% arrhythmic events and 15.3% HF monitoring events. Alerts for HF monitoring including heart rate at rest were increasing and CRT pacing percentage was reduced. Through alerts of the HM, patients got physician advices by telephone in 65 times, parameters were optimized in 11 times, and treatment plan was adjusted in18 times, four patients were hospitalized again. Conclusions: Home monitoring is necessary and safe method which could early detect the abnormal events in the patients with ICD or CRT-D, This system is helpful in making earlier clinical intervention, and optimizing follow-up management, it may improve patients, quality of life and safety.
