Systolic blood pressure measures the arterial blood pressure due to contraction of the heart, whereas diastolic blood pressure is a measure of arterial pressure between heart contractions, according to WebMD. A blood pressure cuff is used to make the measurements; systo...
If someone has high diastolic blood pressure, it does not necessarily mean that they have high systolic blood pressure, notes the Mayo Clinic. It is possible to have isolated high diastolic or isolated high systolic blood pressure.
According to the Centers for Disease Control and Prevention, systolic blood pressure refers to the pressure blood exerts when the heart beats. Diastolic blood pressure refers to the pressure exerted on the blood vessel walls in between the time the heart beats.
Systolic means the maximum blood pressure through the arteries while the left ventricle of the heart is contracting, explains MedicineNet. The systolic pressure is usually the first number in a blood pressure reading. In a blood pressure reading of 110/80, 110 represent...
Causes of high diastolic blood pressure include medical conditions such as hypothyroidism, coarctation and adrenal tumors, according to the American Academy of Family Physicians. High diastolic blood pressure usually has no known cause and tends to run in families.
High systolic blood pressure accompanied by normal diastolic pressure is called isolated systolic hypertension, which is possibly caused by artery stiffness, heart valve problems or hyperthyroidism, according to Mayo Clinic. In many cases, the cause of high blood pressu...
According to the American Heart Association, diastolic blood pressure refers to the amount of pressure against artery walls between heartbeats or when the heart is at rest. The second number in a blood pressure reading, diastolic pressure is considered normal when it is...
