摘要： A portable sleep monitoring system for recording on tape, transcribing and charting a plurality of physiologic data channels recorded relative to a known constant, user-transparent time base. Selected ECG, air flow, impedance and pulse oximetry sensor inputs are recorded under microprocessor control relative to a crystal controlled 40 Hz signal modulated with the physiologic data from one of the sensors. Upon reading the physiologic data from tape and/or charting, the collected data is displayed with the time base, normalized to the known crystal controlled timing signal. In the heart rate mode, QRS occurences are displayed on the heart rate trace line as singular hash marks. The presence of motion at the pulse O2 sensor is indicated by multiplexing high frequency hash markings onto the O2 saturation trace line. Calibration levels relating to four different O2 saturation percent vales are periodically written to tape for reference during tape reading.

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.

摘要翻译： 起搏系统分析仪连接到可植入心脏起搏器，如果只检测到心房起搏脉搏，则分析仪将模拟的P波发送到起搏器，并确定模拟P波的响应，以确定起搏模式是否为AAI ，AAT或AOO。 在分析仪仅检测到心室输出脉冲的情况下，将模拟的R波发送到起搏器，并且如果起搏器通过触发的心室脉搏或不改变其响应来进行响应，则分析仪确定起搏器处于 VVT或VOO模式。 另一方面，如果起搏器被禁止，则向其发送随后的模拟P波，并且该P波的响应确定起搏器是否处于VVI或VDD模式。 在分析仪检测到心房和心室起搏脉冲的情况下，首先将模拟的R波发送到起搏器，并且不变的响应确定起搏器处于DOO模式。 另一方面，如果抑制起搏器使得不产生心室脉冲，则向其发送模拟的P波。 起搏器对模拟P波的响应决定了它是处于DVI还是DDD模式。
