我们对某潜艇支队324名潜艇艇员进行了远航前后心电图观察。远航时间为30至32昼夜。均于航前作常规心电图,返航后立即复查(均在上岸后3h内完成)。现将结果报告如下。一、远航前后心电图改变(见附表) 由表可见,远航后的心电图改变主要是窦性心动过速明显增加(艇员心率普遍加快);ST-T改变增多(为水平或近似水平下移,均<0.1mv,多在Ⅱ、Ⅲ、avF、V_5、V_6导联);左心室高电压减少;少数出现不全性房室传导阻滞及早搏等。二、年龄与心电图改变的关系:324名中,20-39岁303人,40-48岁21人(均为干
We carried out a voyage before and after the 324 submarine crew of a submarine detachment ECG. Voyage time is 30 to 32 days and nights. Before the flight as a routine ECG, return immediately after the review (all completed within 3h after landing). The results reported below. First, voyage before and after the change of ECG (see table) can be seen from the table, voyage after the change is mainly sinus tachycardia significantly increased (crew generally accelerated heart rate); ST-T increased (for the level or approximate level down , All <0.1mv, mostly in Ⅱ, Ⅲ, avF, V_5, V_6 lead); left ventricular voltage reduction; a small number of incomplete atrioventricular block and premature beats. Second, the relationship between age and ECG changes: 324, 303 aged 20-39, 21 people aged 40-48 (all dry
