摘要：
An apparatus (16) for the treatment of atrial arrhythmia, comprising: at least two conductors adapted for operative connection with the implantable therapy generator 5, each conductor comprising: at least one electrode (11) adapted for implantation near a atrium of a patient's heart, to administer far-field impulses； at least one electrode (11) adapted for implantation near the atrium of the patient's heart, to administer near-field impulses and detect cardiac signals； and an implantable therapy generator (506), adapted for implantation in a patient and its operative connection to the electrodes, characterized in that it includes: sensitive circuitry (512), which detects cardiac signals representative of atrial activity and ventricular activity； detection circuitry (514), operatively connected to the sensitive circuitry to evaluate cardiac signals representative of atrial activity, to determine the atrial cycle length and detect an atrial arrhythmia based at least partially on the atrial cycle length； control circuitry (516), operatively connected to the sensitive circuitry, which, in response to atrial arrhythmia, controls the generation and selective administration of a three-stage atrial cardioversion therapy to the electrodes, each stage presenting a delay between stages of between 100 and 400 milliseconds, and without confirmation of the conversion of atrial arrhythmia during atrial cardioversion therapy in three stages； and therapy circuitry (518), operatively connected to the electrodes and to the control circuitry (516), which includes: at least one first stage charge storage circuit (606, 606a), selectively coupled to at least one electrode of far field, which selectively stores energy for a first stage of three-stage atrial cardioversion therapy, which has at least two and less than ten biphasic atrial cardioversion pulses of more than 10 volts and less than 100 volts, with a duration of impulses of less than 10 milliseconds and a pulse coupling interval o
