To examine the interaction between normal and nonischemic areas of the left ventricle during acute ischemia, we implanted midwall ultrasonic segment length gauges in the ischemic zone and in nonischemic areas of the canine left ventricle. During acute ischemia, end-diastolic pressure and segment length in the nonischemic areas increased. There was no change from control in the segment length at the time of aortic valve opening and closure. Thus, in nonischemic areas, total segment shortening… CONTINUE READING
