WebAll patients with implanted asynchronous pacemakers, and those whose demand pacemakers operate in asynchronous mode for any reason, are to be considered at risk from this complication. In patients with serious myocardial abnormalities consistent demand pacing should be assured, even if it requires early pacemaker replacement. WebAll pacemakers respond to a magnet by switching to an asynchronous pacing mode at a programmed atrioventicular delay with a fixed magnet rate.
