BXBX NOVEL Chapter 753: 【753】Heart sounds are strong
The human heart can be roughly seen as a peach in appearance. The peach has a point, like the heart.
When the heart contracts, the apex of the heart hits the front of the chest wall, causing the intercostal tissue to vibrate outward. If you are a thin person, you can see the bang bang bang bulging out of this place with the naked eye. The words heard with a stethoscope are more obvious.
What the doctor listens to the heart with the stethoscope. The first thing to listen to is the heart rate, which is the number of heartbeats per minute. A normal heart rate is 60 to 100 beats per minute.
Many people mistakenly think that listening to the heart rate is to listen to the apex of the heartbeat, which is wrong. The most accurate heart rate measurement in medicine and pulse measurement are not enough. You must listen with a stethoscope. What you hear is not the apex of the heart, but the first heart sound.
Heart sounds have four names in medicine, numbered from the first heart sound to the fourth heart sound in descending order. Among them, the first and second heart sounds can be heard by all healthy people, and the third heart sound can only be heard by some healthy children and adolescents. If the fourth heart sound can be heard, the person is sick.
Each heart sound is a sound made by the activity of the heart. For example, the first heart sound is the start of systole when the mitral and tricuspid valve leaflets suddenly close, resulting in leaflet tension causing vibrations. Understand this truth, if the first heart sound is abnormal, the doctor can judge that there is a problem with the mitral valve and the tricuspid valve.
Xie Wanying frowned. She heard the strong first heart sound from the patient's heart in her ears. The rumbling murmur occurred during diastole, which is a typical sign of mitral valve stenosis.
"What's your name, where are your family members?" Xie Wanying put away the stethoscope first and asked where the patient's family members were. The girl must be hospitalized for this disease, but she didn't know why she was sitting alone at the door.
Just in time, a middle-aged man walked through the crowd and walked back towards them.
The girl saw the man, opened her mouth hard and said to the doctor, "My name is Ma Yunli. He is my father."
The man walked up to Xie Wanying, his eyes widened as if surprised by her appearance.
Didn't you bring your daughter to see a doctor? Why do I see the doctor with this expression. Xie Wanying had doubts in her heart, and said to the patient's family, "She needs to consider hospitalization in this situation."
"Hospitalized?" Lily's father said, "your doctor told her to go home, she won't need treatment."
"Which doctor said that?" Xie Wanying did not think that the teachers in the emergency department of the National Association would make a misjudgment of such a serious heart disease patient.
asked which doctor it was, but Lily's father couldn't tell which one, and said, "How do I know which one it is, you are all wearing white coats. I can't recognize which one it is."
"You told the doctor why she came to the emergency room to see a doctor?" Xie Wanying asked the patient's family, this matter must be clarified. Otherwise, if something goes wrong with the patient later, the family members come to the doctor to hold them accountable, and the doctor and the hospital should be held responsible.
"The school teacher said that she vomited in class and asked me to take her to the hospital." Lily's father's expression fully showed reluctance, "I didn't need to go to the hospital, I can just buy some medicine. Look, now I am being sent to the hospital. rush."
