  The female nurse helped the patient to undress the patient first, exposing the chest for examination.

   Zhao Zhaowei tried his best not to look at the patient\'s chest. However, when he was about to start putting the suction ball of the chest electrode, he knew in his mind that it was located in the fourth intercostal space, but he had to feel it, otherwise how would he know where the sternum was, where the ribs were, and where the ribs were.

  How to determine the location without touching it? Sweat dripped down Zhao Zhaowei\'s forehead.

   After having personal experience, he no longer thought it was easy for Xie Wanying to quickly perform an electrocardiogram on the patient just now.

   "Doctor Zhao." The nurse standing across from the bed reminded him of the time.

   The patient waited for a while, but he couldn\'t put down the first suction ball. The patient had some doubts about what was going on. Also, the patient\'s parents stood outside the bed curtains waiting for the results of their daughter\'s examination.

   The pressure is getting bigger and bigger, Zhao Zhaowei feels that his heartbeat is estimated to be faster than that of the patient now.

   "Can you do it?" Dr. Lin said.

   Zhao Zhaowei bit the bullet: "Yes." Immediately afterwards, he gritted his teeth, no matter what, let\'s put the ball down first, only visual inspection. Fortunately, the girl is thin and can vaguely see signs of ribs.

  Place the ball and turn on the electrocardiograph.

  DiDi, strange, why the electrocardiograph is more impatient than him, and it beeps and spit out paper as soon as it is turned on.

   Zhao Zhaowei was dumbfounded.

   Is this thing broken?

   Looking at the paper again, the graph on the paper is straight and does not look like an electrocardiogram at all.

   panicked, he really panicked: what happened? What did he do wrong?

   That\'s right, he clearly remembered exactly where the electrodes should be placed. Even if there is a deviation from the exact position, it will only be slightly worse, and the resulting graph should not be a straight line.

   Seeing how long the ECG chart was spit on the ground, Xie Wanying, who was standing behind Zhao Zhaowei, quickly helped her classmates put the ECG on.

   "Yingying, do you know what\'s going on?" Dare to look at Dr. Lin\'s eyes, Zhao Zhaowei turned around and asked her in a low voice.

   "It\'s alright." Xie Wanying told him, "You re-sterilized the skin under the electrode, it may be due to poor contact. Turn it on again and press the F2 key, that is the reset button. Press the reset button and it should return to normal."

   "Thank you, Yingying." Zhao Zhaowei turned around and immediately followed the steps she said.

   It turned out that it was not properly disinfected. Zhao Zhaowei breathed a sigh of relief. This time, take an alcohol cotton ball and carefully re-sterilize the patient\'s skin.

   The high school girl\'s body tensed into a candy bar.

   Finally, the ECG machine spits out paper normally, and the ECG is ready. Zhao Zhaowei wiped the sweat from his forehead. When the nurse saw it, she directly helped him remove the electrodes, and pulled the female patient\'s clothes and quilt to prevent the patient from catching a cold.

   "Teacher, take a look." Zhao Zhaowei handed Dr. Lin the ECG drawings made by the patient. At this time, his tone was very guilty, and his confidence at the beginning had been destroyed by the accident just now.

  Doctor Lin looked at him and said, "You are cheating."

   In front of the teacher, he said that he could, and then he turned to ask his classmates, is the teacher blind?

   The nurse next to him almost laughed when he heard this.
