DX Technology
DR Smart. VR Simple. CRT Capable.
The DX system offers complete atrial diagnostics in a single lead ICD, offering the benefits of both single- and dual-chamber ICDs.
Key Facts
- BIOTRONIK ProMRI device and lead systems increase patient access to MRI scanning and give physicians more options to choose from without any compromise on therapy.
- Atrial Diagnostics and SVT Discrimination
- Early detection of silent Afib - up to 79% of atrial high rate episodes are asymptomatic1, but they independently increase risk of stroke and thromboembolic events by 13%2
- Increased diagnostic accuracy - the addition of atrial to ventricular IEGMs increases accuracy for chamber of origin and type of arrhythmia
- Dual-chamber discrimination with SMART Detection® - the only sophisticated discriminator that also works on redetection
- Less Hardware, Less Exposure
- Reduced lead complications - dual-chamber ICDs have a 40% increased risk in peri-operative complications and 45% increased risk in hospital mortality3
- Reduced procedure complexity - less implant time compared to dual-chamber4
- DX system is completed with Plexa S DX - a high performance DF4 MR conditional ICD lead with active fixation and atrial sensing
DX Technology
The BIOTRONIK DX System defines a new paradigm in ICD therapy; it offers dual-chamber diagnostics with a single ICD lead, therefore capturing benefits of both single-chamber and dual-chamber ICDs.
Improving AF Management
Early detection of silent Afib - up to 79% of atrial high rate episodes are asymptomatic1, but they independently increase risk of stroke and thromboembolic events by 13%2
ProMRI with MRI AutoDetect
MRI diagnostics are growing in importance, and cardiac device patients are more likely to need MRIs BIOTRONIK ProMRI technology is tested to exceed ISO standards and is clinically proven through FDA mandated studies.
The BIOTRONIK ProMRI platform offers full body MRI capabilities for the broadest patient population (For newly indicated ICD patients, as well as replacements and upgrades. Additionally, there is a ultra-high energy model for high DFT patients).

Studies
Subclinical Atrial Fibrillation Detection with a Floating Atrial Sensing Dipole in Single Lead Implantable Cardioverter-Defibrillator Systems: Results of the SENSE Trial
- Atrial high rate event (AHRE) detection with a single lead ICD system with atrial sensing dipole is superior than a single-chamber system and equivalent to dual-chamber system. During the one-year of follow-up, atrial sensing amplitude was stable and there were no inappropriate shocks in the DX cohort. The study results show the benefit of the DX ICD system for patients who do not have an atrial pacing indication, but are at risk of developing subclinical AF.
Implantable Cardioverter Defibrillator System with Floating Atrial Sensing Dipole: A Single-Center Experience
- The single-lead ICD system with floating atrial dipole provides reliable atrial sensing amplitude over time. The physician, without the implantation of an additional lead, has the atrial information that may be used for the discrimination of supraventricular tachyarrhythmia/ventricular tachycardia, for the early detection of atrial fibrillation episodes and for the evaluation of changes in the patient's heart status.
Case Study: Remote Monitoring in the Management of a Complex Patient with a Single-Lead Dual-Chamber ICD
- The atrial IEGM was instrumental in confirming the device’s rhythm classifications. It appropriately provided ATP during the VT episode, as well as withheld therapies when faced with self-terminating VF.
Novel Single-lead ICD Provides SVT Discrimination and Atrial Diagnostics
- The addition of atrial IEGM provides confirmation that the rhythm discriminator both appropriately withheld and treated the different episodes. In fact, clinical evidence suggests that the use of atrial IEGMs dramatically improves a clinician’s accuracy of rhythm classification.
