The form of collagen organization defines the distribution and magnitude of strain of the valve during the
cardiac cycle (42).
The highest level is at the peak systole of the first
cardiac cycle t = 0.65 s.
Sixteen frame per
cardiac cycle acquisition resulted larger EDV (82.6 34.3 ml vs 80.9 42.5ml, P=NS) smaller ESV (34.7 31.4ml vs 38.9 40.1ml, P=NS but signif icant) and higher LVEF (63 14.1ml vs 59.1 15ml, P0.05 (NS).
To analyze systole and diastole the
cardiac cycle is usually divided into seven phases.
In the point of view of fPCG signal, [S.sub.x]([alpha], f) must have a peak at heart rate because the heart sounds are dominant cyclic components at the heart rate in adjacent fetal
cardiac cycles. Therefore, detecting FHR is equal to detecting the basic cycle frequency of the digital sequence.
He then discussed in detail
cardiac cycle and ECG, coronary artery system, approach to read ECG, pattern of reading ECG so that one does not miss anything.
Mean arterial blood pressure (MBP) is the average blood pressure in a subject during the
cardiac cycle. Inasmuch as this parameter represents the force to sustain organ perfusion, it should be considered a fundamental cardiovascular variable.
The velocities recorded upstream of the lesion are displayed for one
cardiac cycle in Figures 2 and 3.
