诊断学作业（Diagnostic work） Multiple choice questions (1 points per subject) 1 ECG standard lead A, I, B, II, C, AVR, D, V5, E, AVL 2 what color does the electrocardiogram lead limb lead? A red, B white, C yellow, D green, E black 3 what are the claims about P waves? A represents the left atrial depolarization potential and time B sinus P waves in AVR inversions C P wave time is no more than 0.11s D P wave, the amplitude of the chest lead is not more than 0.25s, E above is not correct 4 whats right about retrograde P waves? A indicates that excitation originates in the atrioventricular junction zone, B, P wave, I II, AVF in the inverted C P wave, and AVR in the upright D stands for ventricular depolarization time and potential above E is correct 5 which statements are correct about normal Q waves?: After the A R wave, the downward first wave, the B R wave, the downward wave C, does not exceed 0.04s The amplitude of D does not exceed 1 / 4 of R wave in the same lead, but E wave can have Q wave in V1 6 myocardial infarction infarct appeared in which lead graphics A, V1, B, V4, C, V2, D, V5, V3, E 7 What myocardial infarction patterns do not appear on the leads in the simple wall myocardial infarction? A II, B, III, C, AVF, D, AVL, E, V5 8 right ventricular infarction, which leads to infarction pattern? A, V3R, B, V4R, C, V5R, D, I, E, AVL 9, the characteristics of junctional premature beat are A B retrograde P wave QRS wave group and sinus can C retrograde P wave in the same wave after QRS D premature offspring compensated more than incomplete E QRS wide malformation Electrocardiographic characteristics of 10 tip twist vt A showed repeated changes of short duration, and the morphological changes of B and QRS were distinct. C could develop into ventricular fibrillation, and D could be persistent E frequency is less than 200 times per minute 11 ECG findings related to atrial flutter are The A P wave disappears and is replaced by F wave, B and P wave. Instead, the F wave, C,
