  • Method and system for characterizing supraventricular rhythm during cardiac pacing
    Patent number: 8583231
    Abstract: A method and system for generating a characterization of one beat of a patient's supraventricular rhythm (SVR) involves performing such characterization while the heart is being paced. During SVR characterization, various pacing parameters are modified and the patient's supraventricular rhythm is characterized while the pacing parameters are modified. The SVR characterization process is effective in single and multiple chamber pacing modes.

  • Method and system for detecting dislodgement of an implanted right atrial endocardial lead using a sensing period derived from a ventrical lead
    Patent number: 6347249
    Abstract: A system and method are provided for detecting dislodgment of a right atrial endocardial lead implanted within a heart right atrium wherein the lead includes an electrode. Heart activity of the right ventricle of the heart and heart activity with the endocardial lead electrode are sensed during a time period. The sensed heart activity is stored in memory. The stored heart activity is analyzed to establish a first time window from the sensed ventricle activity and a second time window spaced from and preceding the first time window. The heart activity sensed with the endocardial lead electrode during the first time window is then compared to the heart activity sensed with the endocardial lead electrode during the second time window. In another embodiment, whenever heart activity is sensed with the atrial endocardial lead during the first time period, the atrial endocardial lead is considered dislodged.

  • Method and system for detecting dislodgment of an implanted right atrial endocardial lead using sensing periods established with one other lead
    Patent number: 5991662
    Abstract: A system and method are provided for detecting dislodgment of a right atrial endocardial lead implanted within a heart right atrium wherein the lead includes an electrode. Atrial and ventricular activity of the heart are sensed with one other lead during a time period. Also during the time period, heart activity is sensed with the endocardial lead electrode. The sensed heart activity is stored in memory. The stored heart activity sensed with the one other lead is analyzed to establish a first time window from the sensed atrial heart activity and a second time window from the sensed ventricular activity. The heart activity sensed with the endocardial lead electrode during the first time window is then compared to the heart activity sensed with the endocardial lead electrode during the second time window.

  • System for detecting atrial fibrillation notwithstanding high and variable ventricular rates
    Patent number: 5827197
    Abstract: There is disclosed an implantable atrial defibrillator for applying cardioverting electrical energy to the atria of a heart when the atria are in need of cardioversion. The atrial defibrillator includes a sense channel adapted to be associated with at least one atrium of the heart to provide a cardiac signal during a plurality of cardiac cycles of the heart and a timer which determines a cardiac interval duration for each of the cardiac cycles. The defibrillator further includes an atrial detector for analyzing the cardiac signal provided by the sense channel during selected ones of the cardiac cycles wherein each one of the selected ones of the cardiac cycles has a cardiac interval greater than a predetermined duration.A cardioverter applies cardioverting electrical energy to the atria responsive to the atrial detector detecting atrial fibrillation of the heart.
