Determination of low hemoglobin level in human using the analysis of symbolic dynamics of the heart rate variability

Symbolic dynamics of electrocardiograms (ECG) carries the information about functioning of various human body systems. A method for distinguishing the men with low hemoglobin value from the men with normal hemoglobin value by analyzing the symbolic dynamics of the heart rate variability was proposed in the research. The method has got an acceptable sensitivity (0.67-0.80) and specificity (0.80-1.00) and works by using a single lead ECG.
