We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Implantation of an implantable cardiac monitor (ICM) subcutaneuously on the left side of the patient's chest/pectoral area. The device itself measures 7.5cm and is itself sterile and located inside the insertion tool. The biomonitor consists of a solid housing made of biocompatible titanium coated in silicone and a flexible silicone lead body. The implantation procedure takes less than one minute and will be performed by a medical doctor on the study. In brief, the procedure is as follows. An incision is made in the skin, whereupon the insertion tool is positioned at the specific location, and the pre-mounted biomonitor is released subcutaneuosly in the left pectoral region. The device remains implanted until sufficient information has been gathered for the doctor to diagnose the cardiac arrhythmia or until the battery runs out after about four years. The device automatically records a number of subcutaneous ECG episodes based on a number of cardiac rhythm related triggers (AF, VT, bradycardia etc). The patient can also prompt a recording by the device when experiencing a syncopal episode using a patient activator device which is supplied.

Diagnosis / Prognosis
Comparator / control treatment
Control group

Primary outcome [1] 308095 0
Assessment of insertion success rate using a new insertion tool + incision tool. Success will be determined based on physicians ease of use of tools, duration of procedure, and a follow up assessment of any adverse events which may be associated with the insertion procedure.

This is a composite primary outcome which will be assessed by study specific questionnaires and also by examining the medical records around the procedure.

Possible adverse events like insertion site discomfort will be assessed by following the patient up over a month and examining their medical records.
Timepoint [1] 308095 0
Implant and 1 month after insertion
Primary outcome [2] 308096 0
Assessment of R-wave amplitude. This will be done via a device programmer which is able to detect these parameters via telemetry. The device programmer is called Renamic and is used as standard of care in cardiac re-synchronization therapy by BIOTRONIK. The information can also be gleaned via wireless remote monitoring.

Implant, 1 week and 1 month after insertion
Secondary outcome [1] 353931 0
Assess the sensing quality of the BIOMONITOR III. This will be done via a device programmer which is able to detect these parameters via telemetry. The device programmer is called Renamic and is used as standard of care in cardiac re-synchronization therapy by BIOTRONIK. The information can also be gleaned via wireless remote monitoring.

Brief summary
BIOMONITOR III First In Man Study aims to collect first implantation experience with a new generation of implantable cardiac monitors. BIOMONITOR III is a miniaturised version of its predecessor BIOMONITOR II which has sought to address the issue of increasing patient comfort with a smaller device, but still having all of the same diagnostic capability as BIOMONITOR II. The objective thus is to examine the ease of implant of the device by physicians, and to assess its full diagnostic capacity on patients.
