During diastole, when the heart relaxes, pressure declines back to 80 mm of mercury. The small secondary pressure increase in the beginning of diastole is referred to as the ‘dicrotic notch’ and is due to closure of the aortic valve and elastic recoil of the aortic wall.

What does the Dicrotic notch represent on the arterial waveform?
The dicrotic notch, or incisura, which interrupts the arterial downslope, represents the closure of the aortic valve, which occurs just moments after the start of diastole. At the end of diastole, the waveform reaches its nadir.
What does Dicrotic wave mean?
dicrotic wave the second portion of the tracing of a sphygmograph of the arterial pulsearterial pulsePulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat by auscultation, traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers.https://en.wikipedia.org › wiki › PulsePulse - Wikipedia or arterial pressure after the dicrotic notch, attributed to the reflected impulse of closure of the aortic valves. Called also recoil wave.
What is the cause of the Dicrotic notch in arterial blood pressure?

Is the Dicrotic notch diastole?
In proximal arterial pressure waveforms, such as from the aorta, the dicrotic notch marks this transition from systole to diastole.
What is the cause of Dicrotic notch?
The dicrotic notch would therefore be the result of a short period of backward flow of blood immediately before the aortic valve closes. Many studies support this theory and have stressed that both events occur simultaneously [14,15].
What causes Dicrotic notch?
During diastole, when the heart relaxes, pressure declines back to 80 mm of mercury. The small secondary pressure increase in the beginning of diastole is referred to as the 'dicrotic notch' and is due to closure of the aortic valve and elastic recoil of the aortic wall.

What causes a Dicrotic notch?
During diastole, when the heart relaxes, pressure declines back to 80 mm of mercury. The small secondary pressure increase in the beginning of diastole is referred to as the 'dicrotic notch' and is due to closure of the aortic valve and elastic recoil of the aortic wall.
What is the cause of the Dicrotic notch in the blood pressure of the brachial artery?
As the dicrotic notch is associated with the closure of the aortic valve, it is usually seen one-third of the way down the descending limb of the pressure wave as it is at this point that the pressure gradients conducive for closure of the aortic valve (pressure in the aortic compartment > pressure in the left ...

What does the Dicrotic notch tell us?
The dicrotic notch is a prominent and distinctive feature of the pressure waveform in the central arteries. It is universally used to demarcate the end of systole and the beginning of diastole in these arteries.
