Detection of abnormal and induction of normal heat rate variability

An apparatus for predicting arrhythmia in a person, comprising,

• a wrist monitor for:
• measuring the heart rate of the person,
• analyzing the measured heart rate to determine a value for at least one marker for Heart Rate Variability;
• and
• comparing the determined value with both a standard predetermined upper limit and a standard predetermined lower limit for the at least one marker, the upper limit indicates decreased variability, and the lower limit indicates increased variability, the at least one marker including at least one parameter of sympathetic or parasympathetic activity, said wrist monitor comprising a microprocessor, memory, a motion detector and an RF transmitter, and
• a communication system comprising at least one member of the group consisting of a phone for communicating with a land line, a cellular telephone, and a pager,
• wherein the at least one marker comprises at least one member selected from the group consisting of Abs.SPS, Abs.AMo, Abs.DX, Abs.DX/M, and Abs.FWHM, Abs.SDANN, Abs.AM, Abs.ANN,Heart Rate, Low HRV, and ACRR, determined over a Time Segment comprising about 25 to about 501 Time Intervals and Points are calculated for the Time Segment, then summed and stored creating an HRV Status report by the wrist monitor, the wrist monitor comprising a microprocessor programed to make said calculations and summing, and memory for said storing.
