    • A multi-speed ECG magnetic tape scanning device for processing and observing in a relatively short interval of time large quantities of ECG signals from two pairs of ECG leads. The ECG information is recorded on a miniature recorder which the patient carries to record the information for a long period of time, such as 24 hours. The recorder includes a built-in clock with a visible display. The recorder also includes an event marker, which is activated by the patient when the patient experiences an event. The play-back of the ECG information is in real time or at multiple high speed play-back speeds of 30, 60 and 120 times real time. During play-back at high speed, a multi-speed multi-channel paper writer reproduces analog trend data, digital printed data and event marking. The trend information is usually heart rate and ST segment level, so as to produce a scanning of an entire 24 hour information tape in as short a period as 12 minutes. The tape scanning device can run on trend to print out trend to the end of the tape, and then stop automatically. Alternatively, the tape scanning device can run on trend to the end of the tape and then automatically cycle to the beginning of the tape to print-out trend and periodically slow the tape down to real time for the print-out of predetermined events in real time. After each print-out in real time, the playback always goes back to the originally selected trend speed for the continuation of the trend print-out. Various short events may be used to slow the read-out to real time, such as an event marking on the tape which has been activated by the patient. Also, any preselected abnormalities in heart function such as abnormal VE's, SVE's, ST level, rapid heart beat, slow heart rate, etc., may be used to print-out in real time. An arrhythmia computer detects and digitally displays the number of premature ventricular contractions (VE) and superventricular ectopic beats (SVE) and actuates the event markers on a paper writer when the arrhythmia occurrences exceed a predetermined number of occurrences during a predetermined time interval. The event marking may also be used to control the slow down during trend read-out to print out the ECG signals in real time to show the arrhythmia occurrences. The arrhythmia computer includes the ability to select one or a number of parameters to determine the occurrence of an arrhythmia. These parameters may be paired beats, prematurity, width or amplitude.

    • Apparatus is disclosed for long-term ambulatory monitoring of blood pressure by an auscultation method, employing a pressurizable cuff and requiring no intervention by the patient. Heartbeats are sensed by ECG electrodes, and a microphone is used to sense the Korotkow sounds as the pressure in the cuff is varied. The presence or absence of a Korotkow sound within a preset interval following each heartbeat is used in determining when the cuff pressure equals the systolic and diastolic pressures. Those pressures are determined in each cycle of operation and are recorded on a continuously-running portable tape recorder, along with the ECG signals. In each cycle of operation, the initial pressure to which the cuff is inflated is based on the systolic pressure measured in the immediately preceding cycle. The pressure in the inflated cuff is thereafter stepped downward in small discrete decrements triggered by successive heartbeats during the measurement phase of each cycle. After both the systolic and diastolic pressures have been determined, the remaining cuff pressure is vented through the same valve that was used to produce the stepwise pressure reduction. After a number of cycles of operation, the magnetic tape is removed from the portable recorder and inserted into an analyzer for high-speed playback and automated plotting of the heart rate and accompanying blood pressure readings on a common chart.
    • 公开了通过听诊方法对血压进行长期动态监测的装置，其使用可加压的袖带并且不需要患者的干预。 ECG电极感应到心跳，并且当袖带中的压力变化时，麦克风用于感测Korotkow声音。 在每个心跳之后的预设间隔内存在或不存在Korotkow声音用于确定袖带压力何时等于收缩压和舒张压。 这些压力在每个操作周期中确定，并与ECG信号一起记录在连续运行的便携式磁带录音机上。 在每个操作循环中，袖带膨胀的初始压力基于在紧接的前一周期中测得的收缩压。 然后，在每个周期的测量阶段，充气袖带中的压力在连续的心跳触发的小的离散衰减中逐步下降。 在确定收缩压和舒张压两者之后，剩余的袖带压力通过用于产生逐步减压的相同的阀排出。 经过多个周期的操作后，将磁带从便携式记录仪中取出并插入分析仪，用于高速播放，并在公共图表上自动绘制心率和伴随的血压读数。
