Abstract
In an arrhythmia discrimination algorithm a timer is used to trigger the delivery of therapy when no diagnosis is made within a defined time during a tachycardia episode. Where one or more rhythm discriminators or qualifiers such as morphology, sudden onset, interval stability and AV association is enabled, the timer starts as soon as a ventricular interval or interval average is faster than a programmed maximum time to diagnosis (MTD) cutoff. If the timer times out before the algorithm diagnoses a particular rhythm, a programmed therapy is delivered. In the preferred embodiment, the therapy that is triggered is a function of the most recent detected ventricular rate and the programmed MTD therapy.
