Carotid vs Radial Pulse Counts.
The Physician and Sportsmedicine
|January 2, 2018
Summary
Carotid pulse counting is a common method for monitoring exercise intensity. This study found that while generally safe for healthy adults, it may underestimate heart rates in some individuals, suggesting specific usage guidelines.
Area of Science:
- Exercise Physiology
- Cardiovascular Monitoring
Background:
- Carotid pulse counting is a widely adopted method for assessing exercise intensity.
- Concerns exist that carotid pulse palpation may trigger the carotid sinus reflex, potentially underestimating postexercise heart rates.
Purpose of the Study:
- To compare pulse rates obtained via carotid palpation, radial palpation, and electrocardiography (ECG) in healthy adults.
- To evaluate the accuracy and safety of carotid pulse counting for exercise intensity monitoring.
Main Methods:
- Twenty asymptomatic adult participants underwent simultaneous monitoring of heart rate using carotid pulse counts, radial pulse counts, and ECG.
- Data were collected to compare the different methods of heart rate measurement.
Main Results:
- Carotid pulse counts were found to be a safe method for many healthy adults to monitor exercise intensity.
- However, at least one participant exhibited lower heart rate counts when using carotid palpation compared to other methods.
Conclusions:
- Carotid pulse counting can be safely utilized by a majority of healthy individuals for exercise monitoring.
- Recommendations for accurate use include proper technique, regular comparison with radial pulse counts, and exercising within the lower target heart rate zones.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

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 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...

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences
1.8K
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.
