Effectiveness and Cost Of ICD Follow-up Schedule With Telecardiology

Study Design

  • Randomized, interventional, multicenter study
  • To compare the safety of continuous Home Monitoring versus conventional ambulatory follow-up of ICDs.
  • 433 patients at 43 centers in France

Key Result 1

Remote follow-up with BIOTRONIK Home Monitoring® is as safe as conventional ambulatory follow-up.

Proportion of Patients

Key Result 2

Continuous monitoring with BIOTRONIK Home Monitoring® reduced the rate of patients who experienced inappropriate shocks significantly by 52%. 72% fewer hospitalizations due to inappropriate shocks.

Inappropriate shocks

Key Result 3

BIOTRONIK Home Monitoring® reduced the number of charged shocks by 76%. Reducing shocks saved 7.9 months of battery longevity.

Clinical relevance

  • The ECOST study shows that BIOTRONIK Home Monitoring of ICDs as a safe alternative to in-office follow-ups. It positively impact on patient outcome , specially when it comes to reducing the risk of inappropriate shocks – a very unpleasant experience.
  • The value of BIOTRONIK Home Monitoring for continuous remote monitoring, through its daily transmissions, is essential for clinics to better manage their patients health condition.
