|  | | These patients still have a normal end-diastolic volume of the left ventricle and normal systolic function. Hypertrophy is also observed, particularly if hypertension is present at the same time. This is best discernible end-systolically in the "pathological" ventriculogram, when the papillary muscles stand out particularly clearly, almost completely filling the apex-adjacent part of the left ventricle. These patients are nevertheless abnormal in the sense that, in part because of the hypertrophy, vigorous exercise leads to a pathological rise of left-ventricular end-diastolic pressure. |
