When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level. The pulse serves as a clinical indicator...

The pulse is one of the most fundamental physiological indicators of the body's cardiovascular health. It is the rhythmic expansion and contraction of the arterial walls in response to the pressure generated by the heart's pumping action. Pulse Rate and its Significance Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls between...

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

An experimental method to examine the early plasma evolution induced by ultrashort laser pulses is described. Using this method, high quality images of early plasma are obtained with high temporal and spatial resolutions. A novel integrated atomistic model is used to simulate and explain the mechanisms of early plasma.
FAQs
The value of a pulse site depends on the artery’s position beneath tissue that allows its expansion to be felt or measured. Sites such as the radial, carotid, brachial, femoral, popliteal, posterior tibial, and dorsalis pedis arteries provide different access points to arterial pulsation. Their distribution enables assessment across multiple regions rather than relying on one location alone.
Assessment should consider pulse rate, rhythm, strength, and symmetry. Rate describes how frequently pulsations occur, while rhythm reflects their pattern. Strength indicates the apparent quality of the arterial expansion, and symmetry allows comparison between corresponding sites. Recording these features creates a broader cardiovascular picture than simply confirming that a pulse is present.
Using more than one location helps clinicians examine whether arterial pulsations are consistent across anatomical regions. The listed sites span upper and lower limbs as well as the neck and groin, so comparison can support recognition of asymmetry or evidence of impaired circulation. This broader examination also helps determine whether further diagnostic monitoring is appropriate.
Clinicians select an arterial site that can be palpated or measured and may use the radial, carotid, brachial, femoral, popliteal, posterior tibial, or dorsalis pedis locations. The chosen site can depend on the purpose of the examination and the need to evaluate a particular region. Findings are then assessed through rate, rhythm, strength, and symmetry.
Pulse-location assessment supports routine examinations, evaluation of impaired circulation, and urgent assessment of hemodynamic changes. Because it is rapid and noninvasive, it can provide immediate cardiovascular information before clinicians pursue additional diagnostic monitoring. The findings may also contribute to decisions about subsequent clinical evaluation and treatment.
Findings can indicate whether arterial pulsation is detectable and describe its rate, rhythm, strength, and symmetry. These observations provide a rapid indication of cardiovascular function and may reveal changes requiring closer attention. Pulse assessment does not replace further evaluation, but it can help guide diagnostic monitoring and treatment when circulation or hemodynamic status is a concern.
