Stratos LV/LV-T Technical Manual  1 
1. General 
1.1 Device 
Description 
The Stratos LV and Stratos LV-T CRT-Ps are rate adaptive 
pacemakers designed to provide Cardiac Resynchronization 
Therapy (CRT).  The Stratos CRT-Ps provide all standard 
bradycardia pacemaker therapy with the additional capabilities of 
biventricular pacing for CRT.  Biventricular pacing in the 
Stratos CRT-Ps can be programmed to initially pace in either the 
right or left ventricular chambers with separately programmable 
outputs for both left and right channels.  Sensing of cardiac 
signals only occurs in the right ventricular chamber.   
The Stratos CRT-Ps can also provide single and dual chamber 
pacing in a variety of rate-adaptive and non-rate adaptive pacing 
modes.  Pacing capability is supported by an extensive 
diagnostic set.  For motion-based rate-adaptation, the 
Stratos CRT-Ps are equipped with an internal accelerometer.  
This sensor produces an electric signal during physical activity of 
the patient.  If a rate-adaptive (R) mode is programmed, then the 
accelerometer sensor signal controls the stimulation rate. 
The Stratos LV-T additionally also employs BIOTRONIK’s Home 
Monitoring™ technology, which is an automatic, wireless, remote 
monitoring system for management of patients with implantable 
devices.  With Home Monitoring, physicians can review data 
about the patient’s cardiac status and CRT-P’s functionality 
between regular follow-up visits, allowing the physician to 
optimize the therapy process.  Stratos 
CRT-Ps are also 
designed to collect diagnostic data to aid the physician’s 
assessment of a patient’s condition and the performance of the 
implanted device.   
The bipolar IS-1 connections are used for pacing and sensing 
(right atrial and ventricle) and the additional IS-1 connection is 
used for pacing in the left ventricle in either a bipolar or unipolar 
configuration depending on the left ventricular lead.  The pulse 
amplitude and pulse width of each of the three channels is 
separately programmable.
