An implantable anti-arrhythmia device such as a defibrillator or anti-tachycardia pacemaker with an associated patient activator. The arrhythmia detection function is divided between the patient and the implanted device, rather than merely providing patient activation or a patient override. The implantable device is provided with a tachyarrhythmia recognition mechanism, which operates essentially continuously, and which, upon meeting a first set of criteria, will trigger delivery of an anti-arrhythmia therapy such as pacing, cardioversion or defibrillation. The patient is provided with an activator which informs the implanted device that the patient believes that anti-arrhythmia therapy is necessary. In response to receipt of the activation signal, the implanted device defines a time interval thereafter during which a second, less stringent set of arrhythmia detection criteria must be met, in response to which the device will deliver a cardioversion or defibrillation pulse.
