Pulse01:16

Pulse

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...
Pulse01:05

Pulse

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...
Regulation of Pulse01:20

Regulation of Pulse

Pulse regulation involves physiological mechanisms that ensure adequate blood flow throughout the body. The heartbeat, regulated by the autonomic nervous system, is influenced by hormonal balance, physical activity, and emotional state.
Special considerations while measuring pulse01:13

Special considerations while measuring pulse

Assessing a patient's pulse is a fundamental skill in healthcare, but certain situations require special attention:
Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
Pulse amplitude and quality01:17

Pulse amplitude and quality

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Summary
This summary is machine-generated.

Resting pulse rate (RPR) declines in older adults, and this decrease is linked to increased longevity. A lower RPR may indicate a better prognosis in the oldest individuals.

Area of Science:

  • Gerontology
  • Cardiology
  • Epidemiology

Background:

  • Resting pulse rate (RPR) is a physiological indicator.
  • Understanding RPR's association with longevity is crucial for aging research.

Purpose of the Study:

  • To investigate the relationship between resting pulse rate (RPR) and longevity in individuals aged 70 to 90.
  • To determine if RPR decline is associated with increased lifespan in the oldest old.

Main Methods:

  • Prospective longitudinal study (Jerusalem Longitudinal Cohort Study, 1990-2010).
  • Participants aged 70, 78, and 85 assessed for RPR, beta-blocker use, and physical activity.
  • Cox proportional hazards models used to analyze mortality data, adjusting for multiple covariates.

Main Results:

  • RPR significantly declined from age 78 to 85 in both men and women.
  • Lower RPR was observed in survivors compared to non-survivors among those not taking beta-blockers.
  • An increased RPR was associated with higher mortality risk across different age follow-up periods.

Conclusions:

  • Resting pulse rate (RPR) declines in the oldest old population.
  • This decline in RPR is associated with greater longevity.
  • RPR may serve as a simple prognostic marker for survival in the oldest old.
