" is the time required by the heart 36 to complete one beat. This cycle is typically manifest by contraction or depolarization of the atria, evidenced by the generation of a P-wave, followed by contraction or depolarization of the ventricles, evidenced by the generation of an R-wave. P-waves and R-waves are evident by analyzing the affected person's electrocardiogram, or ECG. 54 could also be a sign indicating a cardiac occasion, resembling a V-pulse or an R-wave signal, which indicators indicate that the ventricle of the center has both been paced (meaning that a stimulation pulse, e.g. a ventricular stimulation pulse, or V-pulse, has been provided by the pacemaker), or that a ventricular contraction, an R-wave, has been sensed.<br>
+
+<br>34 is advantageously embedded throughout the pacemaker lead 60 at a location near the distal tip so as to put the sensor 34 in the appropriate atrium 38 of the center 36. Further, when positioned properly within the center, the lead is formed in a manner that causes the sensor 34 to face blood (and subsequently measure the oxygen content of blood) just after the blood enters the atrium 38, earlier than such blood has a chance to become totally combined within the atrium. Forty four develops a management sign 49 that is consultant of the reflectance properties of the blood (and hence relatable to the quantity of oxygen within the blood). This management sign 49 is offered to the pacemaker circuits 46 and is used as a physiological parameter to control the rate at which the pacemaker circuits deliver a stimulation pulse to the center. FIG. 3A a waveform diagram illustrating representative fluctuations within the output sign from the sensor 34 of FIG. 2 (when such sensor is placed in the proper atrium 38 of a affected person's coronary heart 36) is illustrated.<br>
+
+<br>FIG. 3A thus depicts the variations within the oxygen content material of the blood as a function of time. At certain times of the day, reminiscent of when the affected person is sleeping, the average oxygen demand is lowest. At different instances of the day, equivalent to when the affected person is exercising, the typical oxygen demand will increase considerably. Thoroughly blended blood, from all body tissue areas, would not exhibit the second variation. However, because the blood is never thoroughly mixed in the fitting atrium, a few of the second variation is always present. 2 and t3 when the sensor output is low, the blood oxygen content is likewise low, indicating a time of relative activity of the patient. FIG. 3B the second type of variation is illustrated. That is, FIG. 3B depicts the type of variations within the blood oxygen measurement that may occur throughout a comparatively brief portion of the waveform of FIG. 3A, e.g., in the course of the portion included within the circle B. As seen in FIG. 3B, such variations in the sensor output could also be relatively abrupt and sudden, evidencing the entry of blood into the correct atrium from body tissue areas having markedly different oxygen content.<br>
+
+<br>A low sensor output, equivalent to at the purpose P1, may be indicative of blood returning from a relatively lively portion of the patient's physique, corresponding to an arm, the place the oxygen demand of the body tissue is high. P3 could also be indicative of inappropriate reflection of light energy into the phototransistor of the sensor prompted, e.g., by a transferring heart valve. 34 doesn't sometimes operate constantly (although it may with applicable circuitry). That is, the sensor is often energized throughout a refractory period of the guts and/or pacemaker circuits, and a "pattern" of the blood oxygen content material at that measurement time is made. Such sample occasions, i.e., those times when a measurement is made, are represented in FIG. 3B as heavy dots equally spaced along the horizontal axis. Statistically, assuming the quick variations within the blood oxygen content are kind of random, some of these sample occasions occur when the blood oxygen content material is low, and others occur when it's excessive.<br>
+
+<br>Hence, within a particular measurement window 70, which "window" 70 includes a plurality of sample occasions, there shall be one pattern measurement that has a decrease value than the others. P1. It is a function of the present invention, to determine the low or minimum measurement within a given measurement window 70, and to use such measurement as an indicator of the relevant blood oxygen content, i.e., to make use of such minimum value as an indicator of the oxygen content material of the blood returning from the physique tissue undergoing the highest oxygen demand. This minimum worth can then be used as a dependable indicator of the physiological need to regulate the guts fee, e.g., as controlled by a price-responsive pacemaker. FIG. 3B suggests that sample measurements made inside the measurement window 70 be equally spaced in time, such equally spaced samples usually are not vital. If sample measurements are taken, all that is necessary is that adequate samples be obtained in order that a statistically correct minimal value might be obtained.<br>
