Sample Medical Article on Hypertension (Demo)
Blood pressure measurement is comprised of two components: the systolic blood pressure, which is the pressure reading when the heart pumps blood, and the diastolic blood pressure, which is the pressure reading when the heart is at rest (not pumping blood). The systolic blood pressure is that part of blood pressure measurement that may vary depending on the type and extent of physical activities that a person is doing. Mental stress due to work, for instance, can lead to increased blood pressure at values beyond the normal (e.g. 122/80 mmHg). Physical activity or workout can also elevate a person’s blood pressure to as high as 150/80 mmHg. However, high blood pressure in a healthy person can easily return to normal through physiological mechanisms. But when it remains high for over a long period of time and occurs frequently, then, it can be hypertension. Blood pressure readings of 140/90 mmHg or above most of the time is clear indication of hypertension. If the readings are mostly above the normal but below 140/90 it is referred to as pre-hypertension.
