    摘要: Various techniques for facilitating selection of a pacing vector for pacing a chamber of a heart are described. A medical deviceis configured, for each of a plurality of vectors, to deliver a pacing pulse to capture a first heart chamber, to determine a first time interval between the pacing pulse and a sensed event in a second heart chamber, to determine a capture detection window in response to the determined first time interval, and to enable a capture detection module to iteratively decrease a pacing pulse magnitude delivered in the first heart chamber until an event in the second heart chamber is not sensed during the determined capture detection window.

    摘要: A medical device and associated method for discriminating cardiac events includes determining whether a first match score is within a first match zone having a first correlation with a non-treatable cardiac event, a second match zone having a second correlation with the non-treatable cardiac event less than the first correlation with the non-treatable event, a third match zone having a first correlation with a treatable cardiac event, and a fourth match zone having a second correlation with the treatable cardiac event greater than the first correlation with the treatable cardiac event. A determination is made as to whether a second match score and a third match score are within the first match zone, the second match zone, the third match zone and the fourth match zone to generate a first adjusting factor, and cardiac event evidence is accumulated in response to the first adjusting factor for discriminating cardiac events.

    摘要: An implantable medical device system includes a pacemaker and an extravascular implantable cardioverter defibrillator (ICD). The pacemaker is configured to acquire a cardiac electrical signal, determine RR intervals from the cardiac electrical signal, apply ventricular tachycardia detection criteria solely to the RR intervals, detect ventricular tachycardia (VT) when the detection criteria are met; and deliver anti-tachycardia pacing in response to detecting the VT before the extravascular ICD delivers a shock therapy.
