摘要： Capture detection and stimulation threshold-measurement methods and apparatus for deriving atrial and ventricular pace pulse (A-pace and V-pace) stimulation energy strength-duration data. In a first atrial and ventricular threshold test regimen for use with patients having intact A-V conduction or first degree AV block, A-pace pulses are delivered at a test escape interval and A-V delay. Atrial loss of capture (ALOC) in response to an A-pace test stimulus is declared by the absence of a detected ventricular depolarization (V-event) in the latter portion of the paced A-V delay interval following the delivery of the A-pace test stimulus. In the ventricular threshold test regimen, a V-pace test stimulus is delivered after a shortened A-V delay. Ventricular loss of capture (VLOC) is declared by the detection of a V-event in the ventricular refractory period of the V-pace test stimulus. In a second algorithm for use in the atrium or ventricle in patients having regular measured sinus rhythm, premature A-pace or V-pace test stimuli are delivered, and the presence of an A-event or V-event at the end of the measured sinus escape interval is declared to be ALOC or VLOC, respectively. A-pace and V-pace test stimuli are repeated to confirm capture declarations at an energy exceeding the LOC test energy. The atrial and ventricular stimulation threshold data derived by varying both pulse amplitude (strength) and width (duration) is stored in memory for telemetry out and analysis and for use in setting the V-pace and A-pace normal pulse width and amplitude used between successive auto-capture tests in order to conserve battery energy.

摘要： There is provided an improved pacing system and method which monitors when the ventricle has become appropriately filled with blood and controls the delivery of each ventricular pace pulse to substantially coincide with desired ventricular filling, e.g., when the chamber has substantially filled. By this technique, the desired time for delivering the ventricular pace pulse is determined on a beat-by-beat basis, providing an improved physiologically optimum mode of pacing. The physiologically ventricular pacing technique of this invention is applicable either to a single chamber pacemaker, or to a dual chamber pacemaker, and in either case enables the important improvement of delivering the pace pulse at the most physiologically appropriate time. In a first embodiment, the moment when the ventricle has substantially filled with blood is determined by monitoring impedance variations which vary inversely with ventricular volume, such that filling of the ventricle corresponds to the time when the impedance waveform bottoms out, or reaches a minimum level. Other sensor arrangements which provide information as to the state of or rate of change of ventricular volume can likewise be used. The invention enables a single lead-single chamber pacemaker which achieves effective synchrony with atrial contractions, or a dual chamber pacemaker which does not require programming of an AV interval.

摘要： A pacing system analyzer as connected to an implantable cardiac pacer and if an atrial pacing pulse is detected only, the analyzer sends a simulated P-wave to the pacer and determines the response of the simulated P-wave to determine if the pacing mode is AAI, AAT, or AOO. In the event a ventricular output pulse only is detected by the analyzer, a simulated R-wave is sent to the pacer and if the pacer responds either by a triggered ventricular pulse or by not changing its response, the analyzer determines that the pacer is in a VVT or VOO mode. On the other hand, if the pacer is inhibited a subsequent simulated P-wave is sent to it and the response of this P-wave determines whether or not the pacer is in a VVI or VDD mode. In the event that both atrial and ventricular pacing pulses are detected by the analyzer, the simulated R-wave is first sent to the pacer and an unchanged response determines that the pacer is in a DOO mode. On the other hand, if the pacer is inhibited so that ventricular pulses are not produced, then a simulated P-wave is sent to it. The response of the pacer to the simulated P-wave determines whether it is in a DVI or DDD mode.

摘要： Methods and devices for determining optimal Atrial to Ventricular (AV) pacing intervals and Ventricular to Ventricular (VV) delay intervals in order to optimize cardiac output. Impedance, preferably sub-threshold impedance, is measured across the heart at selected cardiac cycle times as a measure of chamber expansion or contraction. One embodiment measures impedance over a long AV interval to obtain the minimum impedance, indicative of maximum ventricular expansion, in order to set the AV interval. Another embodiment measures impedance change over a cycle and varies the AV pace interval in a binary search to converge on the AV interval causing maximum impedance change indicative of maximum ventricular output. Another method varies the right ventricle to left ventricle (VV) interval to converge on an impedance maximum indicative of minimum cardiac volume at end systole. Another embodiment varies the VV interval to maximize impedance change.

摘要： A physiologic cardiac pacer operable in the DVI or A-V sequential pacing mode or the DDD or fully automatic pacing mode senses for the omission of an R-wave from an implantable cardiac pacer during the A-V interval. If the pacer does not sense a R-wave during the A-V interval the V-A interval is timed out immediately following the A-V interval and an atrial pacing pulse is issued at the end of the V-A interval. In the event, however, that an R-wave is sensed during the A-V interval, a flag is set and then the entire A-V interval is to be timed out, at which time the state of the flag is determined. If an R-wave was previously issued, a ventricular pacing pulse is not issued to the pacer at the end of the A-V interval, whereas if the flag is not set it is transmitted to the pacer.
