Chapter 753 【753】Strong Heart Sound

The earplugs were hung up, and the listening head was attached to the girl's heart auscultation area, and the routine auscultation started from the mitral valve area. 0.5 to 1 cm inward of the clavicular midline of the left fifth intercostal space, the apex of the heart is the mitral valve area. Here you can hear the beating of the apex of the heart and heart sounds.

The appearance of the human heart can be roughly regarded as a peach. The peach has a point, which is the same as the heart. The point is called the apex, which is specifically described as the conical tip of the lower left part of the heart.

As the heart contracts, the apex of the heart strikes the front chest wall, causing the intercostal tissues to vibrate outward. If it is a thin person, the naked eye can see that this place protrudes outward. Listening with a stethoscope is more obvious.

The doctor stethoscope listens to the heart to listen to what. The first thing to listen to is the heart rate, that is, the number of heartbeats per minute. The normal heart rate is 60 to 100 beats per minute.

Many people mistakenly think that listening to the heart rate is listening to the beating of the apex of the heart, which is wrong. The most accurate heart rate measurement and pulse measurement in medicine are not acceptable. You must listen with a stethoscope. What you listen to is not the apical pulse, but the first heart sound.

There are four names for heart sounds in medicine, 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, it is a sick person.

Each heart sound is a sound made by the activity inside the heart. For example, the first heart sound is the sudden closing of the mitral and tricuspid valve leaflets at the beginning of systole, resulting in vibrations caused by tension in the leaflets. After understanding this truth, if the first heart sound is abnormal, the doctor can judge that there is a problem with the mitral and tricuspid valves.

Xie Wanying frowned, and 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, and where are your family members?" Xie Wanying first put away her stethoscope, 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 in front walked through the crowd and came back towards them.

Seeing the man, the girl tried her best to open her mouth 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 take your daughter to see a doctor? Why do you see the doctor with this expression. Xie Wanying had some doubts in her heart, and said to the patient's family: "She needs to be considered for 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 didn't think the teachers in the emergency department of the National Association would misjudge such a serious heart patient.

When asked which doctor it was, Lily's father couldn't tell which one it was, and said, "I don't 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?" Xie Wanying asked the patient's family members, this matter must be clarified. Otherwise, if something happens to the patient later, the family members will come to the doctor to pursue responsibility, and the doctor's hospital will be responsible.

"The school teacher said she vomited in class and told me to send her to the hospital." Lily's father showed his reluctance, "I don't need to send her to the hospital, I can just buy some medicine. Look, now she is sent to the hospital." Rush away."
