Widening of the QRS complex by terminal notching in leads V1 and V2 was observed in 6 seborrheic patients with adequate personal hygiene. This anomaly disappeared when the presternal skin was degreased thoroughly with cationic detergent before placing the conductive paste and electrodes. We attribute these electrocardiographic alterations to variations in the apocrine secretions in the presternal region, which modified the resistance of the skin to electrical potentials.
在6名个人卫生良好的脂溢性皮炎患者中，观察到V1和V2导联终末切迹导致QRS波群增宽。在涂抹导电糊和电极之前，用阳离子洗涤剂彻底清洁胸骨前皮肤后，这种异常现象消失了。我们将这些心电图改变归因于胸骨前区域顶泌汗腺分泌物的变化，这种变化改变了皮肤对电位的电阻。
