Principles of diagnosis of hypertension

Principles of diagnosis of hypertension

WHO / ISH hypertension treatment guidelines "Hypertension is defined as: not serving anti-hypertension drug cases, the systolic blood pressure ≥ 140 mmHg and / or diastolic blood pressure ≥ 90 mmHg, and" JNC-VI Guide "in line. Blood pressure is a clinical performance, suffering from environmental, emotional, drugs, posture, and many other factors and fluctuations, and therefore determine blood pressure, should be to minimize or exclude the interference of these factors, the extraordinary three times a day resting blood pressure (sit-5 ~ 15min) measuring ≥ 18.7/12.0 kPa (140/90mmHg) after (1997 JNC, 1999年WHO and the Chinese Hypertension 1999 guidelines for the prevention and treatment standards) will be diagnosed with high blood pressure.

Measuring blood pressure in the diagnosis of hypertension is very important, bearing in mind the following principles:

1. Staged a sit-in in the rest state, and to rule out environmental and emotional factors. High blood pressure may be lying in the seat of blood pressure, blood pressure may而立bit low blood pressure in the seat. Each posture changes, 2 min later to be changed after the measurement of blood pressure, blood pressure values of each position deviation <5%.

2. Accurate measurement of blood pressure, is the brachial artery as the standard, cuff to the elbow Waterloo radial profile on the 1 ~ 2 cm. Cuff try not to oppression stethoscope head, playing to a maximum of 20 mmHg systolic blood pressure on the gas, gas-slow, constant speed down to silver Hg, and 2 ~ 6 mmHg / s suitable. Blood pressure readings for the units to mm Hg (mmHg),再换to kPa units.

3. Blood pressure measurement choices to the best desktop mercury column, but also can be e-brachial artery blood pressure table, avoid the use of radial artery and the artery of the electronic blood pressure measuring instrument.

The diagnosis of hypertension should include the following:

a. diagnosed hypertension, that is, whether blood pressure is higher than normal, except for symptoms of hypertension;

b. hypertensive stage, classification;

c. important organs heart, brain and kidney function estimates;

d. whether the merger can affect the development of hypertension and treatment of disease, such as coronary heart disease, diabetes, hyperlipidemia, hyperuricemia, chronic respiratory diseases, and so on.
