摘要： PROBLEM TO BE SOLVED: To provide a cardiac pacemaker with a capture detection algorithm in which atrial capture may be detected and distinguished without adding other components to the device. SOLUTION: A capture detection algorithm detects and distinguishes atrial capture. Atrial chamber reset (ACR) and AV conduction (AVC) algorithms are implemented to measure an atrial pacing threshold. The data that is used to choose between ACR and AVC methods is used to determine the progression of the patient's disease state. Accurate threshold measurements including calculation of stability criteria, precise interval measurements, and the use of reference interval are enabled to determine capture and loss of capture.

摘要： PROBLEM TO BE SOLVED: To provide a device for testing a stimulation threshold energy for using together with a double-chamber or a single-chamber heart pacemaker pulse generator (IPG). SOLUTION: This device for testing the stimulation threshold energy contains a means for determining the period predicting the occurrence of natural depolarization of the heart proceeding the preceding natural or stimulated depolarization, and for defining a time window containing the cease of this period, a means for applying the test pacing pulse of a test energy level to the heart at a certain time during the determination period preceding a predicted natural depolarization followed by the preceding natural or stimulated depolarization by operating the IPG, a means for detecting the heart depolarization by operating a sensing amplifier of the IPG during the period of the test window, a means for declaring the capture of the heart by the test pacing pulse when the heart depolarization is not detected in the test window, and a means for declaring the capture failure of the heart by the test pacing pulse when the heart depolarization is detected in the test window.

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 of 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： A multiple sensor cardiac pacemaker 10 blends the outputs from a fast-reacting Activity sensor 20 and a slower-reacting Minute Ventilation sensor 82, 100 to achieve an optimally desirable pacing rate. The pacemaker conserves battery energy by forcing the Minute Ventilation sensor 82 output to be at its minimum value by disabling the Minute Ventilation algorithm for a predetermined time period when the Activity sensor is at its minimum observed value. Power is conserved because the Minute Ventilation sensor 82 and associated algorithms which normally consume power to operate the circuitry, and to measure impedance are disabled temporarily only during selected periods where the Activity sensor is at its minimum observed value, thereby maintaining optimal blending of the pacemaker sensor outputs in achieving the desired pacing rates.

摘要： There is provided a system and method for increased data transmission from an implanted pacemaker when the pacemaker is in magnet mode. Pacemaker data including, e.g., pacemaker operating conditions, pacing events and patient events, is outputted by changing the asynchronous pacing rate to selected ones of available rates, and with a predetermined sequence, enabling read out of the data on an EKG strip chart. In a preferred embodiment, data-encoded pace pulses with intervals corresponding to selected rates are delivered in a predetermined sequence with fixed rate non-data intervals. For example, four pulses are delivered at 85 ppm followed by one or more data-encoded pulses, each data-encoded pulse being at 90, 95 or 100 ppm, whereafter the sequence is repeated with additional data-encoded intervals. The combination of rates for each of the data-encoded intervals represents the pacemaker data, and can be decoded by observing an EKG strip taken during the pattern of pace pulses. The invention provides for enhanced data transmission from an implanted pacemaker without the need of a programmer for receiving the data, and is thus particularly useful in environments where only a simple magnet is available for pacemaker follow-up.

摘要： CONSTANT A-A INTERVAL CONTROL FOR DVI AND DDD CARDIAC PACEMAKERS 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 priviously 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.

摘要： The identity of a key in a scanned keyboard is determined by the time during the scanning cycle that a particular depressed matrix key location is scanned. The processing circuit, commonly a microprocessor with associated memory elements, is connected to the scanned keyboard conventionally to identify the scanned key. The memory means which are employed have a low power inactive state. The scanned keyboard will be in a low power state as long as no keys of the keyboard are depressed. As long as any of the keys are depressed, however, a gate controls a power safe flip-flop which activates the memory, bringing them to a high power state and the memories remain in the high power state until the processor has completed its processing cycle at which time the processor triggers the flip-flop so that the memories are again allowed to go to their inactive state, thereby achieving a substantial reduction of power in the keyboard which nevertheless remains available for instant activation.
