BIOTRONIK notes Over the past decades, more than 20 clinical studies that enrolled over 4,000 patients have confirmed the safety and efficacy of DX Technology. This strong foundation of clinical evidence has recently been enriched by the MATRIX study results, the largest clinical evaluation of DX Technology to date. Results from the MATRIX study confirm under real-world conditions that DX, with Home Monitoring, allows for reliable, guideline-recommended remote monitoring of subclinical AF.
