心电图运动负荷试验作为心脏疾病诊断与职业飞行人员、运动员心功能检查,已被广泛采用。从最早Bruce倡用的少数改良双极胸前导联,发展到多导联(12或14导联)。不同导联组合,阳性率不同,其敏感性与特异性亦各异,因而探查电极位置与导联数的筛选,在诊断上有重要意义。国产Y-CP1型活动平板与YYG-1型心
ECG exercise load test as a heart disease diagnosis and professional flight staff, athletes cardiac function tests, has been widely used. From the earliest Bruce advocate a few modified bipolar thoracic lead to multi-lead (12 or 14 lead). The combination of different lead, the positive rate is different, its sensitivity and specificity are also different, so to explore the location of the electrode and lead the number of screening, in the diagnosis of great significance.
