Normal pulse measurement reflects the state of health of the person. So what is the pulse rate of a normal person? In the case of a newborn, how many times does the pulse beat in 1 minute?

I have symptoms of dizziness, weak limbs when moving, shortness of breath when lying down, rapid pulse, difficulty sleeping. My blood pressure is normal. I have been like this for two days, taking pain relievers, it helps and I can sleep. So the doctor asked me what is the disease with weak hands and feet, shortness of breath with a fast pulse?
