Non-invasive studies of left ventricular relaxation and filling by means of doppler-echocardiography are of considerable interest owing to easy recording and good reproducibility. However, such physiological parameters as site of measurement, heart rate and, chiefly, age may interfere with the curves obtained. The interpretation of tracings must also take into account the presence of mitral valve pathology (stenosis or regurgitation), aortic stenosis, disorders of atrioventricular (prolonged PR complex) or intraventricular (left bundle branch block) conduction and medication (e.g. vasodilators). In clinical practice, one of the main advantages of the technique is that it makes it possible to distinguish between the physiological left ventricular hypertrophy (LVH) of top-class sportsmen (without impaired ventricular filling) and the pathological LVH of hypertrophic cardiomyopathy. The purpose of this study, with a review of the literature, was to take stock of the value and limitations of the doppler indices.
通过多普勒超声心动图对左心室舒张和充盈进行无创研究，因其记录简便且重复性好而备受关注。然而，诸如测量部位、心率，主要还有年龄等生理参数可能会干扰所获得的曲线。对描记图的解读还必须考虑二尖瓣病变（狭窄或反流）、主动脉狭窄、房室传导障碍（PR间期延长）或室内传导障碍（左束支传导阻滞）以及药物（如血管扩张剂）的存在情况。在临床实践中，该技术的主要优势之一在于能够区分顶级运动员的生理性左心室肥厚（LVH）（心室充盈无受损）和肥厚型心肌病的病理性LVH。本研究结合文献回顾的目的，是评估多普勒指标的价值和局限性。
