Of 78 apparently healthy subjects with positive serological tests for Chagas disease, 29 had EKG abnormalities. On direct questioning only two referred dyspnea, one had palpitations and another one dizziness. The most frequent EKG abnormalities were: peaked T waves in 10 cases; ventricular premature beats in 8 patients, right bundle branch block in 7, left bundle branch block in 5, abnormal ST-T segment in 4, atrial fibrillation in 3 cases, left ventricular hypertrophy in 3, and left anterior hemiblock in 3. As has been previously recognized, the EKG changes plus the positive serological tests are the earliest manifestations of Chagas disease.
在78名查加斯病血清学检测呈阳性的表面健康受试者中，29人存在心电图异常。经直接询问，只有两人提及呼吸困难，一人有心悸症状，另一人有头晕症状。最常见的心电图异常为：10例T波高尖；8例室性早搏，7例右束支传导阻滞，5例左束支传导阻滞，4例ST-T段异常，3例心房颤动，3例左心室肥厚，3例左前分支阻滞。正如之前所认识到的，心电图改变加上血清学检测呈阳性是查加斯病的最早表现。
