10种心电图,1句话牢记!

2015-08-24 日志 人人网

正常心电图: 1.没刻度的: 2. 有刻度的(临床常用): 纵向每一小格代表0.1mV,横向每一小格代表0.04s。(因为心电图机的灵敏度和走纸速度分别是1mV/cm和25mm/s.) P波:<0.25mV, <0.12s QRS波:0.06~0.10s PR间期:0.12~0.20s QT间期:<0.40s. HR(心率):60~100次/min.

正常心电图:


1.没刻度的:



2. 有刻度的(临床常用):


纵向每一小格代表0.1mV,横向每一小格代表0.04s。(因为心电图机的灵敏度和走纸速度分别是1mV/cm和25mm/s.)

P波:<0.25mV, <0.12s

QRS波:0.06~0.10s

PR间期:0.12~0.20s

QT间期:<0.40s.

HR(心率):60~100次/min.



3.所有的12个导联(肢体导联Ⅰ,Ⅱ,Ⅲ,aVR,aVL,aVF;胸导联V1,V2,V3,V4,V5,V6):



各段意义:



纵向每一小格代表0.1mV,横向每一小格代表0.04s。(因为心电图机的灵敏度和走纸速度分别是1mV/cm和25mm/s.)


10种心电图一句话牢记:


1,正常心电图:不用说了,它有可能是把那几个波和导联都斩一段下来,每一个波给你3个周期,分成几行给你看,要注意。(P,QRS,T波;PR,QT间期)


2,左心室肥大:只要看V5大于5格,是上下纵的5格(即V5导联QRS波>0.25mV)


3,右心室肥大:只要看V1大于2,格,是上下纵的2格(即V1导联QRS波中R/S>1,也就是R波>S波的幅度)


4,心房颤动:所有的P--P,Q--Q,R--R,S--S,T--T都没规律,也就是P波的位置上乱七八糟的。可发展为心室颤动。(即P波的位置被 大小不一的小f波取代,而QRS波正常)

心室颤动 :所有的P--P,Q--Q,R--R,S--S,T--T都没规律,正常QRS波消失,只剩下大小不一的小波。此时病人极度危险,随时心室骤停,应及时电除颤。


5,窦性心动过缓:P波正常,且每个心动周期,即两个P波之间,也叫P-P间期,都大于5个大格(25个小格),是左右横的格。

(即P-P间期>1.00s,可算出心率<60次/min )


6,窦性心动过速:P波正常,且每个心动周期都小于3个大格(15个小格),是左右的格。(即P-P间期<0.60s,可算出心率>100次/min )


7,房性期前收缩:前面几个正常的波,接着一个波提前(注意:这个波的pqrst形状是正常的,只是提前罢了),接下去又是正常的波。


8,室性期前收缩:前面几个正常的波,接着一个波提前(注意:这时候R波变宽),接下去又是正常的波。


9,典型心肌缺血:V4,V5,V6的ST段下移。


10,急性心肌梗死Q波增宽+ST段弓背向上抬高,注意:前壁看V1,V2,V3,V4,V5,V6;下壁看Ⅱ,Ⅲ,aVF。

心电图一分不能丢的秘诀!——2015年医师资格技能考试

第一步,看心律是否整齐这一步至关重要,因为关系到后面对心电图的判断,所以第一部一定要看心律是否整齐,RR间期是否都相等。第二步,假如是心律整齐的,看以下步骤:1.看RR间期,小于三大格,心动过速,大于五大格,心动过缓。2.看V1和V5导联,正常心电图V1主波方向向下,V5导联主波方向向上。如果V1或V5的QRS波成“M”型,则考虑束支传导阻滞,表现在V1为右束支,V5为左束支。(这个不用解释吧?)
