Twenty healthy male subjects (age range, 15-25 years; median, 21 years) underwent magnetocardiography during physical exercise. Significant ST-segment displacements of the magnetic signal were found during exercise at a heart rate of 120 beats/min compared to the magnetic signal at rest (P < .001). Since no significant ST-segment changes were found in the electrocardiogram recorded simultaneously with the magnetocardiogram, it is concluded that the magnetocardiogram shows junctional ST-T segment changes earlier than the electrocardiogram.
20名健康男性受试者（年龄范围15 - 25岁；中位数21岁）在体育锻炼期间接受了磁心动图检查。与静息时的磁信号相比，运动期间心率为120次/分钟时发现磁信号的ST段有显著位移（P <.001）。由于在与磁心动图同时记录的心电图中未发现明显的ST段变化，因此得出结论，磁心动图比心电图更早显示交界区ST - T段变化。
