Brief Summary

To demonstrate the value and benefits of BIOTRONIK's exclusive DX technology in assessing the incidence of supraventricular arrhythmias, mainly atrial fibrillation (AF), in patients with an indication for single chamber ICDs. Effects of the DX technology on related events, such as delivery of therapies and medical management, including eventual complications. Extended benefits offered by DX devices when associated with daily remote monitoring, by means of BIOTRONIK's Home Monitoring Service Center (HMSC).

Outcome Measures

Primary Outcomes (1)

• New Onset of Atrial Fibrillation, Atrial Flutter or Supraventricular Tachycardia Recorded Episodes

  All patients enrolled presented with sinus rhythm, confirmed also during the implant. Outcome was considered positive with the occurence of first confirmed episode of Atrial Fibrillation (AF) or atrial flutter (AFL) or supraventricular tachycardia (SVT), detected and transmitted to BIOTRONIK's Home Monitoring Service Center (HMSC), lasting at least 30 seconds to be considered relevant. The adjudication was carried out by the independent investigator in charge of the remote monitoring.

Interventions

BIOTRONIK ICDs with DX Technology DEVICE

The BIOTRONIK DX system offers a single chamber ICD that enables sensing of atrial signals through floating atrial dipoles, using a single ventricular lead. This technology enables enhanced arrhythmia diagnosis based on atrial and ventricular electrograms and, in addition, early diagnosis and automatic transmission of AF and heart failure (HF) diagnostic data. The DX technology provides several features in a single chamber device that are usually only found in dual chamber devices, including atrial diagnostics and SVT discrimination - early detection of SAF, increased diagnostics accuracy, dual-chamber discrimination. Nevertheless, the benefits of a single chamber device are preserved: reduced lead complications, reduced procedure complexity, elimination of costs for atrial lead. The DX system also integrates with BIOTRONIK Home Monitoring, allowing physicians to remotely follow their patients' clinical and device statuses with daily updates.
