Heart Rate Variability (HRV) tells us about the balance between two systems in our body. Think of one system (Sympathetic Nervous System) as the 'action mode' – it gets us ready for things like running or dealing with stress. The other system (Parasympathetic Nervous System) is like the ...
The effect of glucose–insulin–potassium solution on ventricular late potentials and heart rate variability in acute myocardial infarction BackgroundBlunted heart rate variability (HRV) and presence of ventricular late potentials (VLPs) are known to correlate with an increa...

Correlation analysis yielded a geometric mean of 0.238 compared to Heart Rate Variability features, with individual correlations for low-frequency, high-frequency, and their ratio at 0.279, 0.168, and 0.286, respectively. Extending the study to 51 participants, including a different experiment focusing...

The heart rate variability (HRV) is considered to be a good indicator of various cardiac abnormalities. Hence, HRV is preferred. HRV can depict the magnitude of pumping of the heart in the RR interval signals accurately. This work proposes a method to automatically identify CHF using two‐band...
Heart rate variability (HRV) is an indirect marker of the autonomic nervous system. Because of paucity of data, this study sought to determine the optimal thresholds of HRV above which the patients are in pain after minor spinal surgery (MSS). Secondly, we evaluated the correlation between HRV...
