Xelos DR-T

High-energy ICD with Home Monitoring technology

Drug therapy, electrolyte imbalance or disease progression can affect defibrillation thresholds. Up to 10 % of all ICD patients have DFTs higher than 18 J.1 For this patient group, BIOTRONIK’s Xelos® DR-T offers additional safety features in ICD therapy.


High-energy Shock

Up to 36 J shocks are available for high defibrillation thresholds.

BIOTRONIK Home Monitoring Service


An exterior patient device sends trend and event messages automatically from the Xelos DR-T to BIOTRONIK's service center using the cellular phone network. Subsequently, the physician receives a detailed report on the patient's cardiac status.


Critical patients need special attention

BIOTRONIK Home Monitoring® automatically alerts you in case of reduced therapy efficacy (ATPs, shocks, maximum energy shocks and system performance).

Continuous monitoring of disease progression

The transmitted data allow you to monitor ventricular and atrial arrhythmias, as well as the effectiveness of the delivered therapies.

Daily system check

Both the ICD and the lead status remain under your control. BIOTRONIK Home Monitoring informs you automatically, online, and at anytime.

Unique biphasic shock waves

In critical cases, reversed polarity and a short second phase (2 ms) can reduce the defibrillation threshold.2,3,4,5
