Heart rate variability (HRV) analysis from ECG can noninvasively assess stress and predict immune function. This inexpensive method may aid in managing stress-related health risks by indexing immune cell percentages.
Area of Science:
- Cardiology
- Immunology
- Public Health
Background:
- Chronic stress can impair immune function, necessitating effective stress assessment in public health.
- Electrocardiography (ECG) and heart rate variability (HRV) are used for cardiovascular assessment and stress inference.
- The link between HRV-based stress assessment and immune function requires further investigation.
Purpose of the Study:
- To compare stress levels measured by HRV (pNN50) from ECG with immune function indicators (neutrophil, monocyte, lymphocyte percentages) from blood samples.
Main Methods:
- 184 healthy adults underwent a 2-minute ECG recording and blood draw.
- Stress was quantified using pNN50 from ECG data.
- Immune cell percentages were determined from blood samples.
Main Results:
- Stress (pNN50) showed a positive correlation with neutrophil percentages (r = 0.21).
- Stress exhibited negative correlations with monocyte (r = -0.16) and lymphocyte percentages (r = -0.18).
Conclusions:
- HRV analysis offers a viable, noninvasive, and inexpensive method for indexing stress.
- HRV analysis may predict immune function, aiding in the management of stress-related health risks.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
Factors Influencing Heart Rate
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
Functions of the Lymphatic and Immune System
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
Determination of Michaelis Constant and Maximum Elimination Rate
These parameters can be estimated by analyzing plasma concentration data post-drug administration. A notable example of this application is phenytoin, a drug with capacity-limited kinetics. It's recommended that phenytoin should be administered at two...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
