概括

通过CT血管造影的时间密度曲线来估计心脏输出 (CO) 是可行的. 分隔模型和斯图尔特-汉密尔顿方法都与MRI显示了中度的相关性,而分隔模型对于部分数据是可取的.

Cardiac Output and Stroke Volume

Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac...
