Heart rate variability in coronary artery disease
1Department of Medicine, Oulu University, Finland.
Heart rate variability (HRV) measurement from ECG recordings offers insights into autonomic nervous system function. Abnormal HRV in post-heart attack patients signals higher cardiac mortality risk, guiding clinical decisions.
Area of Science:
- Cardiology
- Autonomic Nervous System Physiology
Background:
- Heart rate variability (HRV) quantifies cardiac autonomic modulation.
- Ambulatory electrocardiograph (ECG) recordings are a key source for HRV measurement.
- HRV analysis provides insights into neural and physiological influences on the heart.
Purpose of the Study:
- To highlight the clinical significance of HRV in cardiology.
- To emphasize the prognostic value of HRV in post-myocardial infarction patients.
Main Methods:
- Measurement of HRV using ambulatory ECG recordings.
- Application of various linear and non-linear analytical methods for HRV.
- Analysis of HRV in the context of ischaemic heart disease.
Main Results:
- Abnormal HRV is associated with increased cardiac mortality risk in post-myocardial infarction patients.
- HRV analysis is a crucial tool in clinical cardiology for risk stratification.
- Different HRV measurement methods yield distinct physiological information.
Conclusions:
- HRV measurement is valuable for assessing cardiac autonomic function.
- Abnormal HRV is a significant predictor of mortality in post-infarction individuals.
- Future research may broaden the clinical applications of HRV analysis.

Factors Influencing Heart Rate
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
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...
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 rate...
