On 33 patients with mitralic heart disease (III and IV class N.Y.H.A.) we have carried out polimechanical investigations (ecg, fcg, x-ray examination, external heart impulse record) and the following parameters was determined: 1) interval Q-I sound; 2) interval II sound-OS; 3) Wells's index; 4) Q-I sound/II sound-OS ratio; 5) duration of electromechanical systole of right ventricle; 6) duration of external heart impulse; 7) relative amplitude of E and E1 as percentage of amplitude from E point to nadir point; 8) relaxation isovolumetric time of right ventricle; 9) medium value of pulmonary capillary pressure, total pulmonary resistances, and area of mitral valve. The results demonstrate that there is a correlation between these parameters and the pulmonary blood pressure, whose value is possible to determine as well as haemodynamic investigation. The data indicate validity of non invasive techniques in detecting pulmonary hypertension in mitralic valve diseases.
对33例二尖瓣心脏病（纽约心脏病协会III级和IV级）患者进行了多力学检查（心电图、心音图、X线检查、心外冲动记录），并测定了以下参数：1）Q-I音间期；2）II音-OS间期；3）韦尔斯指数；4）Q-I音/II音-OS比值；5）右心室机电收缩期持续时间；6）心外冲动持续时间；7）E和E1的相对振幅占E点至最低点振幅的百分比；8）右心室等容舒张时间；9）肺毛细血管压、总肺阻力和二尖瓣面积的中值。结果表明，这些参数与肺血压之间存在相关性，其值可以通过血流动力学研究来确定。数据表明非侵入性技术在检测二尖瓣疾病中的肺动脉高压方面的有效性。
