  • Device and method for ventricular tracking and pacing
    Patent number: 8214034
    Abstract: A device and method for multi chamber pacing a patient's heart having heart failure and intrinsic conduction, wherein ventricular tracking is used to pace the ventricle when the sinus rate exceeds a preset atrial maximum tracking rate. The ventricular tracking pacemaker increases the range of pacing the ventricle. The ventricular tracking minimizes the loss of ventricular pacing caused by intrinsic conduction when the sinus rate is below an atrial maximum tracking rate, and it induces a new ventricular pacing behavior for sinus rates above the atrial maximum tracking rate without any significant pacing hysteresis as the sinus rate returns towards the lower rate limit.

  • Automatic capture verification in multisite cardiac pacing
    Patent number: 6128535
    Abstract: An implantable device and method of cardiac stimulation that automatically verifies capture and a threshold effectiveness of stimulation of a cardiac stimulator. During predetermined periods, the device utilizes 2 or more pacing/sensing electrodes positioned within an electrically continuous area of the heart, wherein one electrode is used to provide a pacing stimulus while the other electrode or electrodes are used to verify capture or a threshold effective strength. A predetermined blanking period is provided to avoid detection of the electrical stimulus transmitted to one electrode from a pulse generator. After expiration of the predetermined blanking period the remaining electrodes detect depolarization of the surrounding tissue.

  • Break algorithm for PR+PVARP block
    Patent number: 5741309
    Abstract: A method of pacing a congestive heart failure (CHF) patient's heart using a pacemaker typically capable of bradycardia dual chamber pacing. The method includes an algorithm for resetting the timing interval of the microprocessor based controller of the pacemaker for stimulating the ventricles after a predetermined AV delay, when a legitimate signal associated with atrial events is blocked by a preprogrammed Post Ventricular Atrial Refractory Period (PVARP).
