In long-term space flights cardiac bioelectric activity was measured by vector-electrocardiography using ECG in 12 standard leads. Most marked changes in the form of a decrease in the integral spatial repolarization vector were seen postflight. This parameter did not return to normal during one month postflight. Depolarization vector and vector orientation remained essentially unchanged.
在长期太空飞行中，使用12导联心电图通过矢量心电图测量心脏生物电活动。飞行后观察到最显著的变化是整体空间复极矢量下降。该参数在飞行后一个月内未恢复正常。去极化矢量和矢量方向基本保持不变。
