Physical electrocardiographic monitoring generally refers to human body temperature, heart rate, respiratory rate, and blood pressure. The precise measurement of body temperature in clinical medicine often uses a mercury thermometer to measure axillary temperature, which involves placing the mercury column of the thermometer below 35 degrees Celsius, placing the liquid mercury tip under the armpit, holding it for at least 5 minutes, and then reading the value. The precise measurement of heart rate can be done by touching the pulse rate, which involves counting the pulse rate for about 1 minute.

If the pulse is irregular or varies in intensity, auscultation of the heart sounds in the lungs is required to distinguish between the pulse and the heartbeat. The precise measurement of respiration generally requires the use of instruments, including intensive care unit monitors. The precise measurement of blood pressure can be made using a mercury sphygmomanometer or an electronic blood pressure monitor, which is required to measure the blood pressure of the arm at rest.

Electrocardiographic monitoring is a key indicator of vital activities in a comprehensive physical examination, including human body temperature, heart rate, respiration, and blood pressure. First, body temperature: there are three main methods. Oral temperature: 36.3-37 degrees Celsius. Rectal temperature: 36.5-37.7 degrees Celsius. Axillary temperature: 36-37 degrees Celsius. Second, respiration: the frequency of respiration at rest is between 12-22 times per minute. Third, heart rate: the normal heartbeat of an adult at rest is between 60-100 beats per minute. Fourth, blood pressure: the ideal blood pressure should be systolic pressure below 120 mmHg and diastolic pressure below 80 mmHg.

The definition of electrocardiographic monitoring refers to the four indicators of human body temperature, heart rate, respiration, and blood pressure. The normal body temperature is between 36.3 degrees and 37.1 degrees, and a body temperature above 37.2 is considered fever. The normal heart rate is between 60-100 beats per minute, and normal respiration is between 12-18 times per minute. Normal blood pressure is generally systolic pressure between 90-140 mmHg and diastolic pressure between 60-90 mmHg. Exceeding these values indicates clinical manifestations and is part of the routine physical examination for inpatients.
