Abstract: A pacer subsystem for detecting the existence of tachyarrhythmia including means for measuring the average time interval between successive heart beats and for comparing a sample beat with both a percentage of this average, and with a preset time interval. If the sample beat period is less than both criteria, it is classified as a tachy beat. If the sample beat is longer than either time interval it is classified as a non-tachy beat. Sequences of tachy beats are used to initiate an appropriate therapeutic stimulation regime. The pacer includes a central processing unit 18 and real time controller 22 connected to the heart by lead system 14 and providing functions such as timing, sensing and generating output pulses.

Abstract: The determination of the concentration of compounds such as CO 2 having an influence on the pH of a medium during polarography is described. Characteristics of potaro- grams when obtained in unbuffered electrolytes (the polarogram plateau slope position of the upper knee and half-wave potential thereof) are pH-sensitive. These can be detected electronically and signals processed to provide a measure of such concentrations. In one preferred embodiment (Figure 2) a miniature pO 2 polarographic sensor has cathode channels (A) and (B) biased respectively at -750 mV and -950 mV. The output of channel (A) provides p0 2 as in normal polarography. The output of (B) is divided (6) and further corrected for p0 2 (8,10) to provide pC0 2 . The apparatus is especially useful for simultaneous p0 2 , pC0 2 monitoring in physiological fluids without the need for a separate pCO 2 sensor.

Abstract: An electronic blood pressure meter, equipped with the functions of computing at least a single relative pulse wave amplitude value in relation with a maximum pulse wave amplitude value, computing a blood pressure value from the cuff pressure when an amplitude of the pulse wave signal has coincided with the relative amplitude value during a change in the amplitude value of the pulse wave signal, and using the reference pressure value thus obtained in accordance with a certain arithmetic formula. If desired, a different process may be selected for determining a blood pressure depending on an initial cuff pressure. This electronic blood pressure allows a measurement to be completed in a very short time and minimizes the discomfort of the person whose blood pressure is to measured through reduction of the maximum cuff pressure. Yet the mathematical formula can be reduced to a simple arithmetic algorithm and is therefore easy to implement.

Abstract: A sphygmomanometer includes a pump (34, 154) for applying variable pressure to a blood vessel, a microphone (2, 150) for sensing oscillation which is produced from the blood vessel being pressurized by the pump (34, 154), a pressure detecting section (4, 156) for sensing the pressure being applied to the blood vessel, and a recognizing section (60, 158) for recognizing Korotkoff sounds out of the oscillation detected by the microphone (2, 150). When the recognizing section (60, 158) has recognized a Korotkoff sound, the instantaneous pressure on the blood vessel is detected by the pressure detecting section (4, 156) to measure blood pressure. Recognition of Korotkoff sounds by the recognizing section (60, 158) is inhibited until a predetermined period of time expires since the recognition of a Korotkoff sound, to prevent the tailing of a Korotkoff sound from being recognized erroneously.

Abstract: An inflatable, deflatable cuff, worn by the subect, is coupled to an air reservoir which is at a predetermined pressure which is above systolic pressure. The pressure head is established by a pump mechanism preferably located within the reservoir. When the reservoir is operatively coupled to the cuff. the cuff quickly inflates to a desired artery-occluding initial pressure preparatory to a following blood pressure measuring cycle of operation. The air pump resumes air flow into the reservoir when pressure within the reservoir falls below a predetermined threshold in preparation for a subsequent measurement cycle. The pump also supplies air directly to the cuff should the reservoir contents ever be inadequate to inflate fully the occluding cuff.

Abstract: The deflation of the inflatable and deflatable cuff worn by a subject during automatic sphygmomanometric measurement is accomplished in unequal size decrements and principally in larger steps than 7 Torr. Each step after detection of the initial oscillations is determined in the first instance by reference to a look-up table or an equation as a function of prevailing cuff pressure. This Base Step dimension is augmented by a factor proportional to the last oscillation amplitude, the factor being increased after detection of the maximum oscillation amplitude. A valve mechanism with at least two different effective orifice sizes is used for deflation, the smaller size effective orifice being used first, to maintain control over the decrement step rate while holding the time for decrement within a predetermined limit of 8 msec. per Torr, i.e., maintaining the rate above 125 Torr per second. The valve mechanism can consist of two valves with unequal orifice size, or it can consist of two equal orifice size valves to be used singly for providing the effective smaller orifice. or in parallel to provide the effective larger orifice. Alternatively a single variable orifice valve can be used.

Abstract: A blood pressure cuff is applied about a subject's artery, and inflated above the systolic level thus fully occluding the artery for a full heart cycle. The cuff pressure is thereafter reduced to permit an increasing flow through the progressively less occluded artery, and a measure of the peak amplitudes of the successively encountered blood flow (oscillatory complex) pulses stored in memory. Also retained is the cuff pressure obtaining for each stored complex peak. In accordance with varying aspects of the present invention, the stored complex peak-representing data ensemble is corrected for aberrations: and improved data processing operates on the stored (and advantageously corrected) pulse peak data and the corresponding cuff pressure information to determine the subject's diastolic arterial blood pressure.
