Description of intervention(s) / exposure
Treatment: Devices - ConfirmRx (Insertable Cardiac Monitor)
Other: ConfirmRx (Insertable Cardiac Monitor) - This is a single arm study where in patients with an approved indication for a cardiac monitor will receive a ConfirmRx Device.
Treatment: Devices: ConfirmRx (Insertable Cardiac Monitor)
This study is designed to characterise the safety and performance of the ConfirmRx device by assessing quality of signal attained from the device with changes in posture and physical activity at implant and 30days post procedure. The study is also intended to assess gross migrations of the device at 30days post implant.

Summary
Brief summary
Insertable Cardiac Monitor's (ICM's) such as Confirm Rx™ are leadless devices implanted for long-term heart rhythm monitoring in the diagnosis and management of clinical conditions such as recurrent unexplained syncope, cryptogenic stroke, ventricular arrhythmias and monitoring atrial fibrillations (AF) post ablation. There is limited data on variations seen in signal sensing with changes in physical activity and posture. This single arm, non-randomized, open-label, multi-center, clinical investigation of 100 subjects is designed to characterise the safety and performance of Confirm RxTM by assessing quality of signal attained from the device with changes in posture and physical activity at implant and 30days post procedure. The study is also intended to assess gross migrations of the device at 30days post implant.
