A blood pressure reading has two numbers. Top number, called systolic pressure. The top number measures the pressure in the arteries when the heart beats. Bottom number, called diastolic pressure. The bottom number measures the pressure in the arteries between heartbeats.
High diastolic blood pressure is a type of hypertension. Doctors do not know precisely why it happens, but obesity, high triglyceride levels, smoking, and alcohol may contribute. Doctors describe...
Diastolic BP of 90 or higher is Stage 2 hypertension, which can drastically increase the risk of stroke or heart attack and may require a prolonged regimen of medication. Diastolic BP of 120 or higher means that you're in hypertensive crisis and should call your healthcare provider right away.
Diastolic blood pressure is the second number. It measures the pressure your blood is pushing against your artery walls while the heart muscle rests between beats. Which number is more important? A higher systolic or diastolic reading may be used to diagnose high blood pressure.
Diastolic pressure is the pressure during the resting phase between heartbeats, as coronary vessels supply oxygen to the heart muscle. It’s important to keep the number low, but not too low. The bottom (diastolic) number in blood pressure plays an essential role in heart health.
What Does the Diastolic Blood Pressure Number Mean? The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats.
High diastolic blood pressure is when the lower number in your blood pressure reading is elevated. It indicates pressure in your arteries when your heart is at rest between beats.
Diastolic blood pressure measures the force that’s exerted on your arteries during diastole, when your heart is at rest and relaxing between beats. Together, these two numbers can tell you how hard your heart is pumping or squeezing blood into your arteries, and how slow or fast your heart is filling back up between beats.
The diastolic blood pressure (the number on the bottom) is the pressure when the heart relaxes and fills with blood between heartbeats. Systolic and diastolic are terms related to blood pressure measurement, which gauges the force of blood pushing against the walls of arteries.
Diastole is when the heart muscle relaxes. When the heart relaxes, the chambers of the heart fill with blood, and a person’s blood pressure decreases. Systole is defined by the following...
