Pacing When Exposed to 
Interference

EMI – Computerized systems are subject to (Electromagnetic 
Interference (EMI) or “noise”.  In the presence of such 
interference, telemetry communication may be interrupted and 
prevent programming of the Stratos CRT-P. 
 
A sensed event occurring during the interference interval will 
continuously reset that interval for the corresponding chamber 
without resetting the basic interval.  Depending upon whether the 
interference (electromagnetic interference, muscle potentials, 
etc.) is detected by the atrial and/or ventricular channel, atrial 
and/or ventricular asynchronous pacing at the programmed 
timing intervals will result for the duration of the interference.  
The interference interval has a duration of 125 ms. If the 
detected rate exceeds 480/min (8 Hz), then the interference 
interval remains refractory during the entire basic interval. 
Depending on the programmed pacing mode and the channel in 
which electromagnetic interference (EMI) occurs,

details the resulting pacing modes for the duration of exposure to 
EMI.
