简介:窦性心律合并房性并行心律及频发室早的动态心电图相对复杂,要想准确快速地分析几乎是不可能的,除非借助于心电散点图。时间散点图能显示心律失常发生的时刻及持续时间;Lorenz散点图可反映主导心律与辅加心律各自的电生理特征;差值散点图则能清楚地揭示出Lorenz散点图上重叠难辨的节律信息。这三种散点图相互补充、互为印证,全方位、多角度地刻画了窦性心律合并房性并行心律及频发室早的竞争与干扰过程。掌握心电散点图这种简洁而高效的分析工具和语言,不仅有助于准确快速分析动态心电图,也为深入了解心律失常的电生理意义打开了一扇窗口。
简介:摘要目的研究多发性硬化(MS)患者抑郁的发生率及相关因素.方法应用汉密尔顿抑郁量表(HAMD)对45例MS患者和40名健康体检者进行抑郁评定,以及对MS患者进行日常生活能力量表(ADL)评分,匹兹堡睡眠质量指数量表(PSQI)评分.结果45例MS患者18例(40.0%)伴发抑郁,其中轻度抑郁12例(26.7%),中度抑郁5例(11.1%),重度抑郁1例(2.2%);40例对照组中5例(12.5%)伴发抑郁,其中轻度4例(10%),中度抑郁1例(2.5%).两组相比较差异有统计学意义.(X2=21.458,11.045,4.89,P<0.01).MS患者抑郁组与非抑郁组PSQI总分及各因子比较显示PSQI总分、主观睡眠质量(F1)、入睡时间(F2)、睡眠干扰(F5)差异有统计学意义.抑郁与MS患者ADL评分,睡眠质量,左侧大脑半球病灶,性别相关,(P<0.01).结论MS患者有较高的抑郁发生率,抑郁的程度与ADL评分,睡眠质量,幕上病灶数,性别相关.关键词多发性硬化;抑郁;日常生活能力评分AbstractObjectiveTostudytheincidenceandrelatedfactorsofMultiplesclerosis(MS)patientswithdepression,.Methods45Multiplesclerosis(MS)p(atientsand40healthysubjectswereassessedwithHamiltonDepressionScale(HAMD),aswellasMSpatientswereassessedwithactivitiesofdailylivingADL)scoreandPittsburghSleepQualityIndexScale(PSQI)score.ResultsOf45Multiplesclerosispatients,18cases(40.0%)wereComplicatedbydepresGsion.12cases(26.7%)milddepression,5cases(11.1%)moderatedepression,onecase(2.2%)severedepression.Of40casesinthecontrolgroup,5cases(12.5%)wereComplicatedbydepression.4cases(10%)milddepression,onecase(2.5%)moderatedepression.Thereweresignificantstatisticallydifferentbetweentwogroups(X2=21.458,11.045,4.89,P<0.01).DifferentenceofPSQIscores,subjectivesleepquality(F1),sleeptime(F2),sleepdisturbances(F5)betweendepressiongroupandnon-depressiongroupwerestatisticallysignificant.MSpatientswithdepressionwererelatedwithADLscore,qualityofsleep,theleftcerGebralhemispherelesionsandgenderofpatients(P<0.01).ConclusionsMSpatientshaveahigherincidenceofdepression;MSpatientswithdepressionwerereGlatedwKietyhAwoDrLdsscores,qualityofsleep,numberoflesionsonthescreen,andgender.Multiplesclerosisdepressionactivitiesofdailyliving(ADL)score中图分类号R744.5文献标识码B文章编号1008-6315(2015)12-0094-02
