Stratos CRT-Ps are equipped with a high-precision threshold 
test with a resolution of 0.1 V ranging from 0.1 V to 7.2 V.  The 
threshold test is activated as a temporary program whose 
specific operation is defined by the applicable software version.  
The threshold is determined by observing the ECG.  Likewise, all 
determinations of threshold or threshold margin, by any means, 
should only be performed by use of temporary programming to 
permit immediate reactivation of the permanent program in case 
of loss of capture.  Removal of the programmer head 
immediately stops the test and reactivates the permanent 
program.  Please refer to the appropriate software technical 
manual for a description of the threshold test operation. 

The threshold test should be performed with the pulse width 
programmed to the same value as that selected for the 
permanent program.  To ensure pacing, the pacing rate of the 
threshold test program should exceed the patient's intrinsic rate.
