This trial does not accept healthy volunteersQualifiers
Age 18 or above
Willing and capable of providing informed consent
Class I or IIa indication for implantation of a single-chamber ventricular pacemaker, according to ACC/AHA/HRS guidelines
A life expectancy of at least one year, and is a suitable candidate based on overall health and well-being
Disqualifiers
Patients with complete AV block or other pacemaker-dependent conditions
Any prior sternotomy;

Single group
Treatments tested in this trial
Calyan Pacemaker
DeviceThe Calyan pacemaker is a device designed for implantation in the chest below the xiphoid process, and includes a FlexArm containing stimulation and sensing electrodes. The Calyan pacemaker is implanted using a set of delivery tools and clipped onto the xiphoid process; the FlexArm electrodes are oriented to make contact with the pericardial surface of the heart. Pacing parameters are adjusted wirelessly with a tablet-based programmer that communicates with the Calyan pacemaker via secure Bluetooth.
