Apex beat. 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 cardiac impulse is the vibration resulting from ...
Left lateral decubitus (lying on the left side). This will decrease the distance from wall of the chest to the apex of the heart. This will help to examine the point of maximal impulse. Also, this will help to hear extra heart sounds (S3 or S4). With the patient sitting upright.
Overview. Your pulse is the vibration of blood as your heart pumps it through your arteries. You can feel your pulse by placing your fingers over a large artery that lies close to your skin. The ...
The point spread function ( PSF) describes the response of a focused optical imaging system to a point source or point object. A more general term for the PSF is the system's impulse response; the PSF is the impulse response or impulse response function (IRF) of a focused optical imaging system. The PSF in many contexts can be thought of as the ...
A healthy heart rate for adults over 18 is usually between 60 and 100 beats per minute (bpm). Your number may vary. The best time to measure your resting heart rate is just after you wake up in ...
LVH can be present for a long time before any symptoms become obvious. But when symptoms are present, they can include: angina (chest pain that may worsen during physical activity) dizziness or ...
The J-point is the point at which the QRS complex finishes and the ST segment begins. The J-point may be elevated as a normal variant. The appearance of a separate J wave or Osborn wave at the J-point is pathognomonic of hypothermia or hypercalcemia .
Nerve conduction velocity. Saltatory conduction. In neuroscience, nerve conduction velocity ( CV) is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include age, sex, and various medical conditions. Studies allow for better diagnoses of various ...
