A system and methodology permit facilitated review of atrial pacing threshold testing. Primarily the system allows the ventricular rate to fall substantially below the atrial rate, preferrably to 1/2 the atrial pacing rate. A number of ways to accomplish this are described including forcing mode switches...http://www.google.ca/patents/US5954755?utm_source=gb-gplus-sharePatent US5954755 - Facilitated atrial pacing threshold testing
