Method for the early diagnosis of subacute, potentially catastrophic illness
First Claim
1. A method for early detection of subacute, potentially catastrophic illness in an infant comprising:
- (a) monitoring frequency histograms of RR intervals in the infant;
(b) identifying at least one characteristic abnormal pattern or distribution; and
(c) correlating the at least one abnormal pattern or distribution with said illness.

Abstract
In one aspect of the invention, there is provided a method for early detection of subacute, potentially catastrophic illness in an infant. The method comprises: (a) monitoring heart rate variability in the infant; and (b) identifying at least one characteristic abnormality in the heart rate variability that is associated with the illness. This method can be used to diagnose illnesses such as, but not limited to, sepsis, necrotizing enterocolitis, pneumonia and meningitis. In another aspect of the present invention, there is provided a method for early detection of subacute, potentially catastrophic illness in an infant, which comprises: (a) monitoring the patient'"'"'s RR intervals; (b) generating a normalized data set of the RR intervals; (c) calculating one or more of (i) moments of the data set selected from the third and higher moments and (ii) percentile values of the data set; and (d) identifying an abnormal heart rate variability associated with the illness based on one or more of the moments and the percentile values.

26. An apparatus for early detection of subacute, potentially catastrophic infectious illness in a patient, wherein the patient is an infant, a newborn infant, a toddler, or a child, the apparatus comprising:
-
(a) a monitoring device, continuously monitoring frequency histograms of RR intervals in the patient; and
(b) a microprocessor, identifying at least one characteristic abnormal pattern or distribution in the RR intervals that is associated with the illness. - View Dependent Claims (27, 28, 29, 30, 31, 32)
