1. A medical device system comprising:
a processor configured to:
receive a first cardiac electrical signal and a second cardiac electrical signal associated with a tachyarrhythmia;
construct a third cardiac electrical signal from the first cardiac electrical signal and the second cardiac electrical signal;
determine a first predicted time to detect the tachyarrhythmia from the constructed third cardiac electrical signal according to a first setting of a plurality of settings of a sensing control parameter;
determine a second predicted time to detect the tachyarrhythmia from the constructed third cardiac electrical signal according to a second setting of a plurality of settings of the sensing control parameter;
determine at least one acceptable setting of the sensing control parameter based on at least the first predicted time to detect the tachyarrhythmia and the second predicted time to detect the tachyarrhythmia from the constructed third cardiac electrical signal; and
generate an output based on the determined acceptable setting of the sensing control parameter.
