2011心电图机使用理论考试题答案 The eeg theory test in 2011 Department: name: (C) the following description of the link of the body link electrode is incorrect: (C) A upper extremity plate is fixed to the upper part of the wrist (the medial side of the upper extremity). The lower extremity plate is attached to 7cm above the medial ankle of the lower limb. C yellow end electrodes to right upper extremities; The red end electrodes are connected to the left upper extremities; D green ends with left lower limb; The black end electrodes are placed on the right foot. The following information about the concatenations of the thoracic conductance electrodes is incorrect: (D) A V1 guide: the 4th costal margin of the right margin of the sternum; B V2 guide: the fourth rib of the left margin of the sternum; The CV3 guide: located in the middle of V2 and V4. D V4 guide: the fifth rib in the left axillary line; (C) The A line represents the time B and the horizontal line represents the voltage C (horizontal) represents 0.02 s D per small square (vertical) for 0.1 mV The following information about the P wave is: (D) So that both atria except A representative of the potential change B P wave direction in the I, Ⅱ, V4 ~ V6 lead in all up The P - R phase of the C P wave in the aVR is 0.14 ~ 0.20 s (D) the following are the errors of the t-wave description. A represents the potential change in B T waves when the ventricular complex is in the same direction as the QRS primary wave direction If the T wave of V1 goes up, then the V2, the V2 dot T wave should not go down again D except Ⅲ, lead aVL, aVF, V1 ~ V3, T wave amplitude of the lead shall not be lower than the same l / 5 R wave Typical manifestations of acute myocardial infarction (C) A is an unusually Q wave, the ST segment is pushing down the B ST segment down, the T inversion C abnormal Q wave or QS, ST segment is bowed, and t-wave inversion D abnormal Q wave or QS wave, ST segment down, T inversion The hypertrophy cardiogram of the right
