Full Early Atrial Diagnostics in Single Chamber ICD Patients Using the DX Lead and Home Monitoring in Brazil.

Study Overview
=================
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).

Extended benefits offered by DX devices when associated with daily remote monitoring, by means of BIOTRONIK's Home Monitoring Service Center (HMSC). Primary Endpoint: - First confirmed episode of AF or atrial flutter (AFL) or supraventricular tachycardia (SVT), detected and transmitted to the HMSC. Other events of interest: Rate of successful transmissions received and stored on the HMSC platform; Hospital admissions related to cardiologic outcomes, at any time throughout the FU period; A composite outcome of any of the following device-related complications: Need for any lead repositioning or replacement, pneumothorax, new pericardial effusion, tamponade, procedure-related death or wound infection, within 60 days after the ICD insertion.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: BIOTRONIK ICDs with DX Technology|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.|
