本文复习了100例肺心患者的心电图,发现有27例PTFv_1≤-0.03mm·s。分析了异常PTFv_1和“肺型”P波及A、B、C三型右室肥厚之间的关系,同时发现异常PTFv_1与C型右室肥厚之间的关系比较密切,其与“肺型”P波的出现并不平行,而后者与A型右室肥厚较为密切。鉴于此,PTFv_1不仅反映左心功能状态,右侧心脏疾病亦可引起异常PTFv_1,并对其机理提出初步看法。
This review of 100 patients with pulmonary heart electrocardiogram, found that 27 cases of PTFv_1 ≤-0.03mm · s. The relationship between abnormal PTFv_1 and pulmonary P wave and type A, B and C right ventricular hypertrophy was analyzed. The relationship between abnormal PTFv_1 and type C right ventricular hypertrophy was also found. The appearance of waves is not parallel, while the latter is more closely related to Type A right ventricular hypertrophy. In view of this, PTFv_1 not only reflects the status of left ventricular function, right heart disease can also cause abnormal PTFv_1, and its mechanism proposed a preliminary view.
