Hang the earplugs and put your head on the girl's heart auscultation area. The routine auscultation starts from the mitral valve area. The left fifth intercostal clavicle midline is 0.5 to 1 cm inside, and the apex of the heart is the mitral valve area. Here you can hear the apex pulsation and heart sound of the heart.
The appearance of the human heart can be roughly seen as a peach. The peach has a pointed point, like the heart. The point is called the apex, which is specifically described as the conical tip of the lower left side of the heart.
When the heart contracts, the apex of the heart will hit the chest wall in front, causing the intercostal tissue to vibrate outward. If you are a thin person, you can see the naked eye that protrudes outward from this direction. The stethoscope will be more obvious when you hear it.
What do doctors listen to when listening to the heart with a stethoscope? The first thing they need to listen to is the heart rate, that is, the number of heartbeats per minute. The normal heart rate is 60 to 100 times per minute.
Many people mistakenly think that listening to the heart rate is the pulsation of the heart apex. It is wrong to measure the heart rate in medicine and not measure the pulse. You must use a stethoscope to listen. What you hear is not the pulsation of the heart apex, but the first heart sound.
There are four medical names for heart sounds, and count them down to the first heart sound to the fourth heart sound. Among them, all healthy people can hear the first and second heart sounds, and the third heart sounds are only heard by some healthy children and adolescents. If the fourth heart sounds can be heard, it is a sick person.
Each heart sound is a sound made by movement in the heart. For example, the first heart sound is the sudden closing of the mitral valve and tricuspid valve leaves, which caused the tension of the leaflets caused by vibration. After understanding this principle, hearing the abnormal first heart sound, the doctor can determine that there is a problem with the mitral valve and tricuspid valve.
Xie Wanying frowned, and she heard the strong first heart sound from the patient's heart in her ears. The rumbling murmur occurred during the diastolic period of the heart, which was a typical sign of mitral valve stenosis.
"What's your name? Where are your family?" Xie Wanying put away the stethoscope first and asked the patient's family where it was. The girl must have been hospitalized for this disease, but she didn't know why she sat alone at the door.
Just in time, a middle-aged man was walking through the crowd and walking back towards them.
The girl saw the man and tried hard to say to the doctor: "My name is Jack Ma. He is my father."
The man walked to Xie Wanying, his eyes widened as if he was surprised by her appearance.
Didn’t you take your daughter to see a doctor? Why did you see the doctor’s expression? Xie Wanying felt puzzled and said to the patient’s family: “She needs to consider hospitalization in this situation.”
"Inpatient?" said Lily's father, "You doctor said that she would go home and there was no need to treat it."
"Which doctor said that?" Xie Wanying did not think that the teachers in the National Association's emergency department would make misjudgment on such a serious heart disease patient.
When asked which doctor it was, Lily's father couldn't explain it clearly and said, "How can I know which one it is? You all wear white coats. I can't recognize which one it is."
"You told the doctor what was going on in the emergency room?" Xie Wanying asked the patient's family that this matter must be clear. Otherwise, if something happened to the patient, the family members would come to the doctor to hold him accountable, and the doctor and the hospital would be responsible.
