Several factors can contribute to the loss of variability, including:
- Chronic Diseases: Conditions such as diabetes, hypertension, and heart disease can lead to reduced variability. - Medications: Certain drugs, like beta-blockers, can decrease HRV. - Acute Illnesses: Infections or acute phases of chronic diseases can also reduce variability. - Stress: Both physical and emotional stress can lead to lower variability. - Age: Variability naturally decreases with age.
