1. A method for operating a cardiac rhythm management device, comprising:
- sensing cardiac electrical activity via a plurality of sensing channels;
outputting pacing pulses through plurality of pacing channels in order to pace both ventricles in accordance with a cardiac resynchronization pacing mode; and
, storing data received from one or more selected sensing channels in a memory upon detection of a triggering condition indicating a decrease in pacing frequency over a specified period of time.

Abstract
A method for operating a cardiac rhythm management device used for cardiac resynchronization therapy in which the storage of diagnostic data is triggered by detection of a condition indicating that the effectiveness of the therapy has been compromised. Such diagnostic data may be electrograms or marker/interval data acquired from the sensing channels of the device.

18. A cardiac rhythm management device, comprising:
-
a plurality of sensing channels, each such channel comprising an electrode connected to a sense amplifier for sensing cardiac electrical activity;
a plurality of pacing channels, each such channel comprising an electrode connected to a pulse generator for delivering pacing pulses to a heart chamber;
a controller for controlling the delivery of pacing pulses and for receiving data from the sensing channels;
wherein the controller is programmed to;
pace both ventricles in accordance with a ventricular resynchronization pacing mode; and
,store data received from one or more selected sensing channels in a memory upon detection of a triggering condition indicating a decrease in pacing frequency over a specified period of time. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
