Assessment of the Cardiovascular System III: Palpation

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

Exercise Stress Test

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Area of Science:

Neuroscience
Physiology

Background:

Growing interest in remote methods for assessing interoception, the perception of internal bodily states.
Concerns exist regarding the data quality from remote interoception assessments.
The Phase Adjustment Task (PAT) is a novel smartphone-based measure of cardiac interoceptive accuracy.

Purpose of the Study:

To compare the performance of the PAT administered remotely versus in a laboratory setting.
To validate the use of the PAT for remote data collection.
To assess the reliability of remote interoception measurements.

Main Methods:

Data from 205 participants (119 remote, 86 laboratory) were analyzed.
Participants completed the Phase Adjustment Task (PAT) via a smartphone application.
Performance was compared between remote and laboratory groups, with and without matching on demographics and after a screener task.

Main Results:

No significant differences in cardiac interoceptive accuracy were found between remote and laboratory participants.
These findings remained consistent after matching groups on demographic variables.
Results were also robust when considering only participants who passed a screener task.

Conclusions:

The Phase Adjustment Task (PAT) is suitable for remote administration.
Remote administration of the PAT yields data quality comparable to laboratory settings.
This validates the use of the PAT for collecting larger, more diverse interoception datasets.
