To determine whether or not diaphragm electromyography recorded from chest wall surface electrodes (EMGsur) can be used to distinguish central from obstructive sleep apnea.
Ten patients (age (44 ± 10) years, body mass index (25.9 ± 1.8) kg/m²) with suspected obstructive sleep apnea referred from Guangzhou Institute of Respiratory Disease were studied between January and September 2009. EMGsur and diaphragm electromyography from esophageal electrode (EMGeso) were recorded during conventional overnight full polysomnography. And chest-abdominal movement was measured with chest and abdominal bands.
High-quality EMGsur and EMGeso were recorded in all subjects except for one who could not tolerate a multipair esophageal electrode. Excellent correlation was found between EMGsur and EMGeso during sleep including apnea events (r = 0.81 ± 0.06, P < 0.05). The central sleep apnea events diagnosed by EMGeso were exactly the same as those diagnosed by EMGsur. However, the central sleep apnea events diagnosed by EMGsur were less than those diagnosed by conventional thoracic-abdominal bands (7 ± 11 vs 28 ± 31, P < 0.05).
EMGsur may be used to distinguish central from obstructive sleep apnea events.
确定从胸壁表面电极记录的膈肌肌电图（EMGsur）是否可用于区分中枢性与阻塞性睡眠呼吸暂停。
2009年1月至9月，对从广州呼吸疾病研究所转诊的10例疑似阻塞性睡眠呼吸暂停患者（年龄（44±10）岁，体重指数（25.9±1.8）kg/m²）进行了研究。在常规整夜全多导睡眠图检查期间记录EMGsur和来自食管电极的膈肌肌电图（EMGeso）。并用胸带和腹带测量胸腹部运动。
除1例不能耐受多对食管电极的患者外，所有受试者均记录到高质量的EMGsur和EMGeso。睡眠期间包括呼吸暂停事件在内，EMGsur和EMGeso之间存在极好的相关性（r = 0.81±0.06，P <0.05）。EMGeso诊断的中枢性睡眠呼吸暂停事件与EMGsur诊断的完全相同。然而，EMGsur诊断的中枢性睡眠呼吸暂停事件少于传统胸腹带诊断的事件（7±11比28±31，P <0.05）。
EMGsur可用于区分中枢性与阻塞性睡眠呼吸暂停事件。
