Electrocardiographic Manifestations in Patients with Uterine Myoma

Electrocardiographic manifestations in 114 patients with uterine myoma were investigated. Classification of electrocardiograhic patterns was based on the Minnesota Code. No reportable electrocardiogram items were recorded in 24 patients (21.2% of the 114 myoma patients. High-amplitude R waves were found in 23 patients (20.4%), depressed ST segments were recorded in 28 patients (24.8%), and abnormal T waves, such as flat or negative T, were noted in 14 patients (12.4%) of the 114 patients with myoma. Some of these items are explainable by anemia due to excessive uterine hemorrhage in myoma patients. However, it could be concluded that all of these electrocardiographic changes are characteristic of anemic patients. Further studies on cardiovascular disturbances in myoma patients will be needed.
