Aims: The purpose of this prospective study was to investigate whether internet-based remote monitoring offers a safe, practical, and cost-effective alternative to the in-office follow-up visits of patients with an implantable cardioverter defibrillator (ICD).
Methods and results: Forty-one patients (62 ± 10 years, range 41–76, 83% male) with previously implanted ICD were followed for 9 months. One-hundred and nineteen scheduled and 18 unscheduled data transmissions were performed. There were no device-related adverse events. Over 90% of the patients found the system easy to use. Physicians reported the system as being very easy or easy to use and found the data comparable to traditional device interrogation in 99% of the cases. They were able to address all unscheduled data transmissions remotely. Compared with the in-office visits, remote monitoring required less time from patients (6.9 ± 5.0 vs. 182 ± 148 min, P < 0.001) and physicians (8.4 ± 4.5 vs. 25.8 ± 17.0 min, P < 0.001) to complete the follow-up. Substitution of two routine in-office visits during the study by remote monitoring reduced the overall cost of routine ICD follow-up by 524
per patient (41%).
Conclusion: Remote monitoring offers a safe, feasible, time-saving, and cost-effective solution to ICD follow-up.
