The apex beat (lat. ictus cordis), also called the apical impulse, [1] is the pulse felt at the point of maximum impulse (PMI), which is the point on the precordium farthest outwards (laterally) and downwards (inferiorly) from the sternum at which the cardiac impulse can be felt.
The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
Apical pulse: located in the 5th left intercostal space, 1.25 cm lateral to the mid-clavicular line. In contrast with other pulse sites, the apical pulse site is unilateral, and measured not under an artery, but below the heart itself (more specifically, the apex of the heart).
Left ventricular function can be assessed by determining the apical impulse. A normal or hyperdynamic apical impulse suggests good ejection fraction and primary MR. A displaced and sustained apical impulse suggests decreased ejection fraction and chronic and severe MR. This type of murmur is known as the Castex Murmur. Holosystolic (pansystolic)
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
Having a pulse over 100 bpm is called tachycardia. The condition can be brought on by anything from dehydration or excessive caffeine intake, to smoking or anxiety. Fatigue, nausea, sweating, and ...
Another, non-obstructive variant of HCM is apical hypertrophic cardiomyopathy (AHCM or ApHCM), [39] also called Yamaguchi syndrome. It was first described in individuals of Japanese descent. Sakamoto was the first to report the condition's ECG pattern in 1976.
A fast radio burst, or a strong pulse of energy, was tracked to a distant long-dead galaxy that astronomers never thought could produce such a signal. A fast radio burst, or a strong pulse of ...
