摘要： A pacemaker control method and apparatus for determining the presence of atrial tachyarrhythmias uses a true interval value and compares it to a predetermined tachy value. The true interval value is updated based on the presence of far field R waves in PVARP that meet certain sequencing criteria. The criteria selected allows the control method and apparatus to reduce or eliminate event sequences that will generate false positive tachy detection and subsequent mode switching, while still allowing for the detection of tachy events in PVARP.

摘要： An AV search method and apparatus is taught with some variation described. It allows a pacemaker to find the appropriate AV interval so as to avoid pacing in the ventricle when it is not necessary, even if there is intermittent AV conduction in the patient. Also, an adaptive PVARP method and apparatus is disclosed that allows the PVARP and AV interval to be adjusted together automatically.

摘要： A method and apparatus for the simultaneous administration of multiple pacing therapies in which two or more pacing features which operate to cause the dynamic adjustment of a common operational parameter of a pacing system are activatable at the same time. In one embodiment, a prioritization among multiple pacing features is established, such that when two (or more) features which operate to cause adjustment of a common operational parameter, a lower-priority feature will not override an adjustment made by any higher-priority feature.

摘要： A rate-responsive cardiac pacemaker implements a novel pacing mode, identified as ADIR/VVIR, which is especially effective for patients with Sick Sinus Syndrome and only intermittent atrioventricular block. Within the same pacemaker circuitry, an AAIR pacemaker and a VVI pacemaker (with an escape rate below that of the AAIR pacemaker) are provided with atrial blanking following both atrial and ventricular events. Ventricular blanking after atrial pacing is minimized for better detection of R-waves following an atrial paced event.
摘要翻译： 速率响应心脏起搏器实现了一种新颖的起搏模式，被认为是ADIR / VVIR，其对于患有窦性窦综合征的患者和仅间歇性房室传导阻滞特别有效。 在相同的起搏器电路中，AAIR起搏器和VVI起搏器（逃逸率低于AAIR起搏器）在心房和心室事件之后都提供心房消隐。 心房起搏后的心室消隐最小化，以便更好地检测心房起搏事件后的R波。

摘要： A method and apparatus for variable rate cardiac stimulation, wherein sudden drops in the rate of delivery of stimulation pulses are avoided by means of rate smoothing and peak rate support functions. In one embodiment, circuitry in a cardiac pulse generator detects atrial events and maintains an updated value of the A-A time intervals between certain atrial events. If a preset ratio or total of these A-A intervals are found to have been shorter than the updated value by at a least a predetermined amount of time, a rate smoothing function is activated wherein the rate of delivery of stimulating pulses is prevented from changing, from cycle to cycle, by more than a predetermined maximum amount. A peak rate support function preferably employs the same updated value in the computation of "escape" intervals. Following the latest A-A interval, if that A-A interval is less than the updated value, then the updated value is used as the new escape interval. If the latest A-A interval is greater than or equal to the updated value but less than the previous updated value, the current escape interval is used as the new escape interval. If the latest A-A interval is less than both the previous updated value and the current updated value, the value updated is used as the new escape interval, and the pulse generator enters a decay mode wherein the escape interval is gradually and incrementally lengthened to prevent sudden changes in the rate of delivery of stimulation pulses.

摘要： A method and apparatus for cardiac pacing, in which pacing pulses are provided at an increased rate in response to a detected rapid drop in heart rate. A rapid drop is detected in response to heart rate falling from a persistent rate above a first threshold rate to a stable rate below a second threshold rate. If spontaneous depolarizations are detected while pacing at the increased rate, pacing at the increased rate is terminated.

摘要： An atrial and ventricular pacemaker including an atrial pulse generator having the capability of delivering high rate atrial pacing pulses for electrophysiologic study and having the capability of delivering ventricular pacing pulses as a backup, during delivery of high rate atrial pacing pulses. Delivery of backup ventricular pacing pulses may be preconditioned upon the occurrence of a desired number, proportion or pattern of occurrences of paced ventricular beats preceding delivery of high rate atrial pacing pulses. Timing of ventricular backup pulses is synchronized to delivered atrial pacing pulses which occur closely timed to expiration of a defined ventricular escape interval for backup pacing. The defined escape interval for ventricular backup pacing may be set as a function of the average interval separating ventricular events preceding initiation of high rate atrial pacing.
