Systolic blood pressure is the maximum blood pressure that can be measured during contractions. Systolic blood pressure is often more concerned because this index indirectly assesses the blood supply and contractility of the heart.
Systolic blood pressure and diastolic blood pressure are two important cardiovascular indicators that help us understand our health status. It helps the patient and the doctor both monitor and adjust to normal.
Many people do not know the difference between the concepts of blood pressure, what is systolic and diastolic blood pressure, as well as how to read, and the medical significance of each of these numbers. So what is blood pressure? What is systolic blood pressure? What is diastolic blood pressure ? Let's follow the article below to understand more about these indicators with SignsSymptomsList.
Blood pressure - What is systolic blood pressure?
Blood pressure is one of the important indicators that each of us must periodically monitor to know if our body is healthy or not, at risk of cardiovascular diseases or not. For the elderly, they often pay more attention to the systolic blood pressure in their blood pressure measurement results.
What is blood pressure?
For healthy people, blood pressure during the day will be higher than at night. In particular, when we exercise too much, are under mental pressure or have vasoconstriction (due to being cold, taking drugs that affect the contraction of the heart, eating too much salt) can cause high blood pressure. suddenly.
When the body is relaxed and comfortable, blood pressure can drop. In addition, in a hot and warm environment, the body sweats a lot, diarrhea, dehydration or vasodilator use... can also lower blood pressure.
Blood pressure is the force of blood against the walls of blood vessels
What is systolic blood pressure? How important?
Systolic blood pressure is the pressure the blood exerts on the artery walls when the heart contracts. Systolic blood pressure is often more concerned because this index indirectly assesses the blood supply and contractility of the heart.
This is the larger number (or upper number) of the blood pressure reading, which is the maximum blood pressure when the heart contracts. According to the World Health Organization, normal systolic blood pressure ranges from 90 to 140 mmHg when measured correctly, if it is above 140 mmHg, it is called systolic hypertension.
What is isolated systolic hypertension?
In Vietnam, high blood pressure is identified as the leading cause of cerebrovascular accident, myocardial infarction, heart failure, ... and occurs most commonly in the elderly.

Isolated systolic hypertension is one of the abnormal forms of blood pressure
What is the difference between systolic and diastolic blood pressure?
In blood pressure readings, diastolic pressure is conventionally the smaller number after systolic blood pressure. This is the lowest level of blood pressure in the blood vessels, occurring between the contractions of the heart and when the heart muscle is relaxed. Diastolic blood pressure is often overlooked because this index only evaluates the elasticity of the vessel wall.
When measuring blood pressure with a sphygmomanometer, the diastolic blood pressure reading is marked at the time when the last heart beat is heard before it can no longer be heard. Normal diastolic blood pressure ranges from 60 - 90 mmHg, if the systolic blood pressure is < 90mmhg="" or="" blood="" pressure="" heart="" diastolic="">< 60= "" mmhg="" then="" is="" see="" is=""> low blood pressure .
Effects of abnormal systolic blood pressure
Abnormally high or low systolic blood pressure is not good for the body and sometimes leads to dangerous diseases.
Sudden increase in systolic blood pressure causes patients to feel severe headache, neck and shoulder fatigue, heart palpitations, chest tightness , shortness of breath, blurred vision... Blood pressure measurement shows a rapid increase in systolic blood pressure. may rise to 200 mmHg or more. If not timely intervention can cause brain stroke, heart stroke such as cerebral hemorrhage, myocardial ischemia, ...
When the systolic blood pressure drops suddenly, the brain and other organs in the body are reduced to the amount of blood supply oxygen, this makes the patient feel dizzy, lightheaded, dizzy, palpitations, heart palpitations, More serious can be confusion, fainting, loss of consciousness, cerebral ischemia and brain death, which is life-threatening.
