Method and arrangement for predicting perioperative myocardial ischemia

摘要

A method and an arrangement for predicting perioperative myocardial ischemia. In the invention heart rate measurements are carried out for example at night- and day-time before the operation to obtain heart rate data. The heart rate data obtained is carried to a device configured to carry out heart rate variability analysis (HRV). Dynamic heart rate variability measures are carried out by utilizing fractal analysis from the heart rate data obtained and fractal correlation properties obtained from the heart rate data measured are examined to find considerable lowering of the fractal correlation properties during for example night-time when compared to day-time.
