At this time, the patient slowly opened his eyes and looked at Wu Xiangdong in front of him in confusion. It was obvious that he did not know what happened just now.

He opened his mouth and wanted to speak, but found that something seemed to be stuck in his throat, which made his face flush with anxiety.

When Wu Xiangdong saw this, he immediately comforted him: "Uncle, I am a doctor. You are in the emergency room of the hospital now. You had a heart attack on the road just now, and we just rescued you."

Wan Zhihua on the side also pointed to the endotracheal tube in his mouth and explained: "You can't speak now because there is a tube inserted in your airway. I will remove it for you when your condition stabilizes.

You can talk now, it's okay, don't be nervous."

With their constant comfort, the originally nervous patient gradually became relieved. When he understood the ins and outs of the matter, even though he could not speak for the time being, his eyes when he looked at Wu Xiangdong were full of gratitude, and even the corners of his eyes were full of gratitude.

Tears flashed.

"Don't be excited. Just stay in bed and take care of yourself now. There may be some examinations that require your cooperation later. Don't worry, we will cure you."

Wu Xiangdong's words were very simple and made people feel at ease. Seeing that the patient's mood gradually calmed down, Wu Xiangdong said to Li Yanan who was standing aside: "In this way, I will go to the clinic to give medical orders later. You first complete his blood routine, coagulation, myocardial damage markers, etc."

Blood test."

"Okay." Li Yanan nodded, got the blood collection needle and blood vessel directly from the treatment cart, and began to draw blood from the patient.

Wu Xiangdong then looked at Wan Zhihua at the bedside, "Lao Wan, since the patient is awake, you can give him an oxygen tube and put it directly on the tracheal intubation port to let him breathe on his own. You can do the rest for me.

For an electrocardiogram, it is best to do an 18-lead electrocardiogram directly to check the condition of the myocardium on the left heart and posterior wall."

"Eighteen-lead electrocardiogram?" Wan Zhihua was stunned after hearing Wu Xiangdong's medical advice. He must have never been exposed to this type of electrocardiogram before.

Li Yanan, who was drawing blood from the patient, also raised his head after hearing Wu Xiangdong's 18-lead electrocardiogram.

Seeing their confused expressions, Wu Xiangdong suddenly realized that at this time, the concept of 18-lead electrocardiogram had not yet become popular in hospitals.

At this time, except for some doctors in the cardiology department of Hamada Hospital who knew how to perform 18-lead electrocardiogram examinations, other departments had just completed the equipment of even 12-lead electrocardiograms.

"That's it." Wu Xiangdong thought for a moment and said to them: "Anyway, the 18-lead electrocardiogram also requires the cooperation of others. I will demonstrate it to you so that you will know how to operate it if you encounter this type of patient in the future."

After all, the 18-lead dynamic electrocardiogram is a more advanced non-invasive heart disease examination method. It can obtain a large amount of comprehensive dynamic electrocardiogram data to realize the application value in the diagnosis of coronary heart disease, myocardial ischemia, and arrhythmia.

Seeing that Wu Xiangdong was going to demonstrate the operation of the 18-lead electrocardiogram in person, the two people present were very excited. Wan Zhihua even ran to the equipment room aside and pushed the electrocardiograph machine that had been there for a long time.

After drawing blood, Li Yanan also looked at Wu Xiangdong expectantly. After all, such an operation was a rare thing for her.

"I believe you have all been exposed to 12-lead electrocardiograms." Wu Xiangdong plugged in the power supply on the electrocardiograph, then turned on the button. As the screen lit up, straight lines appeared in front of everyone's eyes.

Wu Xiangdong divided the ten lines on the electrocardiograph into two parts. The four lines with electrode pads are limb leads. They are divided into four colors: red, yellow, green and black, representing the six standards I, II, III, avR, avL and avF.

lead.

The remaining six chest leads equipped with electric suction rubber balls are in six colors: red, yellow, green, brown, black, and purple, representing a total of six chest leads of V1, V2, V3, V4, V5, and V6.

Wu Xiangdong placed them on the patient according to their respective functions and positions. The original straight lines on the electrocardiogram machine changed instantly. As the patient's electromechanical signals were continuously received and summarized by the machine, they eventually formed twelve lines with different shapes and amplitudes.

Different leads electrocardiogram.

"This is the 12-lead electrocardiogram." Wu Xiangdong looked at the electrocardiogram signal fed back from the electrocardiograph, and decisively pressed the start button. With a beeping sound, the bearing on one side of the machine began to rotate, and a picture with a grid pattern appeared.

The electrocardiogram gradually appeared in front of everyone's eyes.

However, Wu Xiangdong did not tear it off immediately. Instead, he changed the rubber ball on the patient's body from the patient's left heart to the right heart, and then pressed the start button on the electrocardiograph.

At this time, as the electrocardiogram paper was slowly spit out from the machine, Wu Xiangdong pointed to the waveform above and said: "The 18-lead electrocardiogram is based on the usual 12-lead electrocardiogram plus six parts of the electrocardiogram. It is often used for suspected patients.

It is an electrocardiogram of acute inferior wall myocardial infarction complicated by posterior wall myocardial infarction and right ventricular infarction."

After Wu Xiangdong finished speaking, the wheels of the electrocardiograph stopped rotating. He grabbed the spit out electrocardiogram and with a crisp sound, he took out an electrocardiogram nearly half a meter long.

He pointed to the chest leads on the left side of the electrocardiogram and explained to Wan Zhihua and the others: "This is an electrocardiogram based on the 12-lead electrocardiogram with the addition of three leads: V3R, V4R, and V5R. If there is

ST segment elevation and pathological Q waves can diagnose right ventricular infarction."

"Similarly." After Wu Xiangdong finished speaking, he pointed to the chest leads on the right side of the electrocardiogram and continued: "Here are the three additional leads V7, V8, and V9. If the above problems occur in these three leads,

It can be proved that he had a myocardial infarction in his posterior wall."

After saying this, Wu Xiangdong put down the ECG chart and looked at the two of them, only to find that the latter was looking at him blankly, the expression on his face seemed to have stopped.

For a moment, the entire rescue room was silent, and the needle drop could be heard. The awkward atmosphere made Wu Xiangdong couldn't help coughing, and then the two of them were brought back from the trapped state.

"What's wrong?" Wu Xiangdong frowned and looked at them: "Why do you look so stupid? Is it because what I said is too difficult?"

As soon as these words came out, the two of them were instantly off guard. Not only Li Yanan, but also Wan Zhihua, who always claimed to be knowledgeable, couldn't help complaining: "Brother, your major is general surgery, how about cardiology?"

He’s also good at professional stuff.”

"You've been talking for a long time, but I didn't understand a word." Wan Zhihua covered his temples, feeling like his head was about to explode: "You said you, the surgery was so smooth, why do you have sub-professional knowledge?
