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...

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center The cardiac assessment is one of the core examinations performed by almost every physician whenever encountering a patient. Disorders of the cardiac system are among the most common reasons for hospital admission, with conditions ranging from myocardial infarction to congestive heart failure. Learning a complete and thorough cardiac examination is therefore crucial for any practicing physician.

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
Sensors can measure periodic blood-volume fluctuations in tissue or pressure-related signals associated with heartbeats. These distinct signal types provide the physiological input for identifying repeated cardiac activity. The selected sensing approach therefore determines whether the recorded data primarily reflect changes in tissue blood volume, pressure-related behavior, or both within the study design.
Analysis can produce both pulse rate and the timing of individual pulse events. Rate summarizes how frequently rhythmic activity occurs, while timing preserves information about when each event appears in the recording. Retaining both measures allows investigators to compare cardiovascular patterns across baseline assessments, treatment periods, and other experimental conditions.
Cardiac measurements provide a physiological readout that can be examined alongside tumor, molecular, and cellular findings. This combined perspective helps characterize systemic effects associated with tumor progression or anticancer therapy rather than focusing only on tumor measurements. It also supports evaluation of cardiovascular responses that may accompany treatment-related changes in the organism.
A study first uses a sensor capable of detecting blood-volume fluctuations or pressure-related signals, then records the periodic cardiovascular activity it detects. The resulting signal is converted into pulse rate and timing data for analysis. Investigators can compare these measurements with the planned physiological, treatment, or disease-related observations to interpret changes over time.
Researchers can collect measurements at baseline to characterize cardiovascular physiology in patients or experimental models, then repeat them during treatment or other study stages. This approach is useful when the project examines cardiovascular responses, tumor progression, or systemic effects of anticancer therapy. Repeated measurements can provide physiological context for interpreting changes in cancer-related data.
Pulse rate and timing data can be linked with molecular, cellular, and tumor measurements within the same research analysis. Such integration connects cardiovascular observations with biological and disease-related findings, helping investigators examine whole-body responses and treatment safety together. The combined dataset can show how physiological changes relate to tumor-associated or therapy-associated measurements.
