On each beats of the heart, the heart pumps out the blood into the arteries. The blood pressure will be high on each beat of heart because it pumps the blood, it is called systolic pressure and when the heart is at rest, between beats two consecutive beats the blood pressure falls, it is the diastolic pressure. The blood pressure reading uses these systolic and diastolic pressures. They are mention as one above or before the other. A typical reading of 120/80 or lower is normal blood pressure140/90 or higher is high blood pressure120 and 139 for the top number, or between 80 and 89 for the bottom number is pre-hypertension Usually high blood pressure has no symptoms, but it can cause serious problems like stroke, heart failure, heart attack and kidney failure. You can control high blood pressure through healthy lifestyle habits and taking medicines, if needed. Low Blood Pressure Hypotension, LBPYou've probably heard that high blood pressure is a problem. So what about low blood pressure?Blood pressure is the force of the blood that pushing against the walls of arteries. On each beats of the heart, the heart pumps out the blood into the arteries. The blood pressure will be high on each beat of heart because it pumps the blood, it is called systolic pressure and when the heart is at rest, between beats two consecutive beats the blood pressure falls, it is the diastolic pressure. They are mention as one above or before the other.Usually they're written one above or before the other, such as 120/80. If the blood pressure reading is 90/60 or lower than have low blood pressure or hypotension. Some people have low blood pressure all the time and they have no symptoms. Their low readings are normal for them. In other people, blood pressure drops below normal because of some event or medical condition. Some people may experience symptoms of low pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.
