. AV pacing showed only minor changes in comparison to sinus rhythm (Tables 1 and 2).
Sorin dual-chamber ICDs feature the Parad+ arrhythmia discrimination algorithm which, according to a 2007 study, reduces the number of inappropriate shocks; and the Safer pacing mode
which, according to a 2012 study, minimizes unnecessary ventricular pacing.
Indications for permanent pacing and pacing mode
prescription from 1989 to 2006.
The concern is that the stimulus presented during the study might be interpreted as cardiac in origin and temporarily inhibit or trigger output, or that it could be interpreted as noise and temporarily cause reversion to an asynchronous pacing mode
, which could lead to dangerous tachyarrhythmias or cause inappropriate reprogramming of the device, she said.
Pacemakers can respond to electromagnetic interference (EMI) in a plethora of unwelcome ways: complete inhibition of pacing, asynchronous pacing, rapid pacing, mode reset to a very safe pacing mode
, or physical damage to the generator and/or pacing leads.
There was a significant improvement in exercise and symptom scores in DDD compared with VVI pacing mode
. These findings, although preliminary, are in accord with the observations of others  and serve to support the central tenet that it is no longer acceptable to withhold physiological pacing from patients with advanced atrioventricular block on the grounds of age alone .
Unlike ACap™ management, ACM did not use ER sensing to determine capture, but introduced premature atrial pacing and sensed atrial or ventricular response according to the pacing mode
to assess atrial threshold.
