心电图入门（Introduction to ECG） A normal ECG report is given below: (1) fill in the name, medical record number, heart rate, PR interval, QRS time limit and so on. (two) 1, P wave: I, II, aVF leads erect, aVR lead inversion, time limit and amplitude normal. Normal PR interval. 2 and QRS wave group: time limit and amplitude are within normal range. 3, ST paragraph: no offset. 4 and T wave: the time limit and amplitude are normal, and there is no pathological excursion. (three) diagnosis: normal electrocardiogram How to watch ECG (I) look at the value 1 heart rate: normal to 60-100. 60bpm reported sinus bradycardia, and 100 reported sinus tachycardia. 2 and P wave: normal time 120ms. 120ms is also reported in Shuangfeng, which is called mitral P wave (sometimes seen, not much) Limb lead 0.25mv, chest lead 0.15mv, and report lung type P wave. 3 and PR interval: normal time 120-200ms, 200ms reported one degree atrioventricular block; 120ms reported short PR interval. The 4 and QRS intervals should be 120ms, greater than this value, which is diagnostic (later); amplitude (positive and negative waves) added to the absolute value: Limb guidance 0.5mv and / or thoracic guidance 0.8mv report left ventricular low voltage (less rare), tender baby does not remember. 5, Rv52.5mv, and (or) Rv5+Sv14.0mv (male) //3.5mv (female), reported left ventricular high voltage, very, very common! Department of left ventricular hypertrophy, medical history, hypertension, visual ECG, QRS wave group increased significantly. 6, P/QRS/T: XX/XX/XX, the number of intermediate shaft - -30 DEG -90 DEG left axis eccentric left axis eccentric left axis eccentric left axis deviation (common), 90 degrees - 180 degrees right axis deviation (not much) but also the specific indexing, in the light of severe, general are moderate, and the degree and above was reported on the map, display these values, so the normal range of the above data must first memorize to talk about the pictures. (two) to see if there is no
