主动脉瓣口面积计算的 Gorlin 方程式较繁杂故 Hakki 等提出一种简易公式:主动脉瓣口面积本文研究这种简易公式在心动过缓或心动过速患者中应用的可靠性.方法:单纯主动脉瓣狭窄患者68例,其中男32、女36,平均年龄62±17岁(20～86岁).进行标准的导管插入.用 Fick 原理测定心输出量,并同时记录左室和升主动脉压,用 Gorlin 和 Gorlin 方程式,及 Hakki 等的简易公式来计算主动脉瓣口的面积.每个患者都用两种方法计算出主动脉瓣口面 Gorlin equation of the aortic valve area is complicated. Hakki et al. Proposed a simple formula: aortic valve area. This article studies the reliability of this simple formula in patients with bradycardia or tachycardia.Methods: Aortic valve stenosis in 68 patients, male 32, female 36, the average age of 62 ± 17 years (20 to 86 years) standard catheterization. Fick principle was used to measure cardiac output and left ventricular and ascending aorta Pressure, using the Gorlin and Gorlin equations, and Hakki et al’s simple formula to calculate the area of ​​the aortic valve orifice.Each patients used two methods to calculate the aortic valve surface
