  • Patent number: 5209229
    Abstract: An implantable device and a method for the automatic detection of atrial arrhythmias and for providing low energy atrial cardioversion therapy for such arrhythmias, with minimal tissue damage and power drain, is disclosed. The device is capable of being incorporated within, and is disclosed as part of, an implantable automatic pacemaker defibrillator/cardioverter having the ability to also provide high energy ventricular defibrillation therapy, as well as dual chamber antitachycardia pacing therapy and bradycardia support pacing. Tripolar atrial and ventricular endocardial leads, each including tip and ring pacing electrodes and a braid cardioverting electrode therein, are employed in conjunction with a subcutaneous electrode lead in delivering therapy from the device to the patient, allowing the device to be implanted in and used by a patient without the need to open the patient's chest cavity.

  • Patent number: 5191884
    Abstract: A multiprogrammable, telemetric, implantable defibrillator contains a high energy shock system to revert VT/VF's to normal sinus rhythm and a multi-programmable VVI bradycardia support system. When the apparatus is in an automatic shock sequence, there are two points of reconfirmation: at the programmed minimum time to shock and after the full charge has been reached, or at thirty seconds, whichever comes first. Reconfirmation involves testing the tachycardia detection output (TDO). If the TDO is high, reconfirmation occurs. If the TDO is low, reconfirmation will not occur and the device will subsequently dump the discharge. Two reconfirmations must occur before a shock is delivered to the patient. If the TDO is low at either reconfirmation, the charge will be dumped.

  • Patent number: 4940054
    Abstract: An apparatus and method for tachyarrhythmia reversion uses multiple sensitivities programmed for automatic operation. A first (medium) sensitivity is used normally for the detection of sinus rhythm and ventricular tachycardia. A second (higher) sensitivity is designed for differentiating ventricular fibrillation from asystole. A third (lower) sensitivity can also be programmed into the device to differentiate between R-waves and high amplitude current of injury T-waves which may occur post shock. Following the delivery of antitachycardia therapy in the form of either antitachycardia pacing therapy or cardioversion shock therapy, there is a pause, or post therapy pacing delay for a period of time prior to the commencement of bradycardia support pacing. The magnitude of the delay period is substantially greater than the normal bradycardia support pacing standby interval.

  • Patent number: 4869252
    Abstract: An apparatus and method for controlling pulse energy in an arrythmia control device wherein bradycardia pacing pulses are normally delivered at a first energy, and after antitachycardia therapy, bradycardia pulses are delivered at a second energy, the second energy being greater than the first energy. The antitachycardia therapy may be at least one of antitachycardia pacing, cardioversion and defibrillation; and is delivered at a third energy level greater than said second energy level. The second energy level is maintained for a predetermined period of time and then returned to the normal bradycardia pacing energy.
