摘  要:目的探讨儿童青少年体位性心动过速综合征(POTS)卧位与立位心电图T波及ST段振幅变化。方法选取2013年8月至2016年1月因不明原因头晕、头痛、晕厥等症状在本院儿童晕厥专科门诊就诊、通过直立倾斜试验(HuTT)诊断为POTS的儿童青少年74例(POTS组);按年龄和性别匹配同期在我院儿童保健门诊健康检查的儿童青少年64例为对照(对照组)。描记卧位与立位12导联体表心电图,程序自动分析结合人工干预测量卧位与立位心电图的心率及12导联心电图T波和ST段振幅。结果(1)立位与卧位比较:POTS组心率增加[(105.2±16.3)次/min比(83.8±18.0)次/min,t=-7.598,P〈0.01)],Ⅰ[(0.28±0.14)mV比(0.33±0.11)mV,t=2.598,P〈0.05)]、Ⅱ[(0.28±0.12)mV比(0.39±0.13)mV,t=5.340,P〈0.01)]、Ⅲ[(0.00±0.19)mV比(0.07±0.11)mV,t=3.041,P〈0.01)]、aVF[(0.14±0.13)mV比(0.23±0.11)mV,t=4.505,P〈0.01)]、V4[(0.33±0.21)mV比(0.51±0.23)mV,t=4.938,P〈0.01)]、V5[(0.37±0.10)mV比(0.50±0.15)mV,t=7.764,P〈0.01)]、V6[(0.254-0.10)mV比(0.37±0.10)mV,t=7.538,P〈0.01)]导联T波振幅降低,aVR导联T波振幅增高[(-0.27±0.11)mV比(-0.36±0.10)mV,t=-5.023,P〈0.01)],V5导联ST段振幅增高[(0.07±0.04)mV比(0.06±0.04)mV,t=-2.309,P〈0.05)]。(2)与对照组比较:POTS组心率差增加[(-21.4±14.0)次/min比(-10.7±11.4)次/min,t=4.875,P〈0.01)],Ⅰ[(0.05±0.10)mV比(-0.01±0.15)mV,t=~3.161,P〈0.01)]、Ⅱ[(0.11±0.12)mV比(0.07±0.12)mV,t=一2.243,P〈0.05)]、V4l(0.18±0.18)mV比(0.07±0.20)mV,t=-3.282,P〈0.01)]、V5[(0.18±0.11)mV比(0.14±0.13)mV,t=-2.013,P�Objective To investigate the changes of amplitude of T wave and ST segment between the supine and orthostatic electrocardiogram in children and adolescents with postural tachycardia syndrome (POTS). Methods A total of 74 children and adolescents diagnosed as POTS by head-up tilt test (HUTI'), who complained of unexplained dizziness, headache, syncope or other symptoms, were chosen as POTS group. A total of 64 children and adolescents who did the health check in our child health clinic were selected as control group by age and sex in the same period. All the cases in this study came from the syncope specialized clinic or inpatient department of the Second Xiangya Hospital, Central South University, from August 2013 to January 2016. The heart rate and the 12-lead T-wave and ST-segment amplitude of the supine and orthostatic electrocardiogram were measured by software and manual intervention. Results ( 1 ) Compared with supine electrocardiogram, the heart rate of orthostatic eleetrecardiogram of POTS group increased ( 105.2 ± 16.3 ) times/min vs. ( 83.8 ± 18.0 ) times/min, t = - 7. 598, P 〈 0. 01 ], the T-wave amplitude decreased in lead Ⅰ [ (0. 28 ±0.14) mVvs. (0.33±0.11) mV,t=2.598,P〈0.05], Ⅱ[(0.28 ±0.12) mV vs. (0.39 ±0. 13) mV,t =5. 340,P 〈0. 01], Ⅲ[ (0. 00 ±0. 19) mV vs. (0. 07 ±0. 11) mV,t =3.041, P 〈0.01 ] ,aVF [(0. 14 ±0. 13) mV vs. (0. 23 ±0. 11) mV,t =4. 505,P 〈0. 01 ] ,V4 [ (0. 33 ±0. 21 ) mV vs. (0.51 ±0. 233 mV,t =4. 938,P 〈0.01 ] ,V5[ (0. 37 ±0. 10) mV vs. (0. 50 ±0. 15) mV,t =7. 764,P 〈 0.01] and V6[ (0. 25 ±0. 10) mV vs. (0.37 ±0. 10) mV,t =7.538,P 〈0. 01 ] ,the T-wave amplitude increased in lead aVR[ ( -0. 27 ±0.11) mVvs. (-0.36±0.10) mV,t= -5.023,P〈0.01],and the ST- segment amplitude increased in lead V5 [ (0.07 ±0.04) mV vs. (0.06 ±0.04) mV ,t = -2. 309 ,P 〈0.05].
