What is the definition of systole?

What is systole and diastole?

Your systolic blood pressure is the top number on your reading. It measures the force of blood against your artery walls while your ventricles — the lower two chambers of your heart — squeeze, pushing blood out to the rest of your body. Your diastolic blood pressure is the bottom number on your reading.

What is the definition of diastole?

Reviewed on 3/29/2021. Diastolic: Referring to the time when the heart is in a period of relaxation and dilatation (expansion). The noun for diastolic is diastole. (The final letter in “diastole” is pronounced as a long “e” as in “lee.”)

What is systole in biology?

Systole: The time period when the heart is contracting. The period specifically during which the left ventricle of the heart contracts.

What is a systole in medical terms?

Systolic: The blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole.

Is 150 90 A good blood pressure?

They’re both measured in millimetres of mercury (mmHg). As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you’re over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.

What causes the diastolic to be high?

A: A high diastolic blood pressure (80 mm Hg or higher) that stays high over time means you have high blood pressure, or hypertension, even when systolic blood pressure is normal. Causes of diastolic high blood pressure include both lifestyle factors and genetics, but the disease is multifactorial.

What is normal blood pressure by age?

Normal Blood Pressure By Age

Age SBP DBP
21-25 120.5 78.5
26-30 119.5 76.5
31-35 114.5 75.5
36-40 120.5 75.5

Where is blood pressure the highest?

Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.

Is diastolic top or bottom?

The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle. This is called systolic pressure. The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure.

What is diastole in anatomy?

Diastole, in the cardiac cycle, period of relaxation of the heart muscle, accompanied by the filling of the chambers with blood. … Initially both atria and ventricles are in diastole, and there is a period of rapid filling of the ventricles followed by a brief atrial systole.

What does ventricular systole mean?

Ventricular Systole refers to the phase of the cardiac cycle where the left and right ventricles contract at the same time and pump blood into the aorta and pulmonary trunk, respectively.

What would a blood pressure reading of 138 86 mm Hg be considered?

Under the current guidelines: Normal: Less than 120/80. Elevated: Systolic between 120-129 and diastolic less than 80. Stage 1 hypertension: Systolic between 130-139 or diastolic between 80-89.

Which is more important systolic or diastolic blood pressure?

Over the years, research has found that both numbers are equally important in monitoring heart health. However, most studies show a greater risk of stroke and heart disease related to higher systolic pressures compared with elevated diastolic pressures.

What is the lower level of blood pressure called?

Diastolic pressure.

The bottom number in a blood pressure reading refers to the amount of pressure in your arteries when your heart is at rest between beats.
