| 发明名称 | Methods and apparatus for quantifying the risk of cardiac death using exercise induced heart rate recovery metrics | ||
| 摘要 | Methods and apparatus for assessing cardiac risks based on heart activity data obtained during a recovery stage of an exercise test of a specific patient. An embodiment of a method comprises determining a prognostic period of the heart activity data after a time t0 after a peak heart rate of the exercise test, and ascertaining a risk indicator. The risk indicator is based on (a) the heart rate activity data during the recovery stage only after time t0 and (b) a post-exercise heart rate reserve based on a post-exercise resting heart rate. This embodiment of the method further includes providing an assessment of cardiac risk of a specific patient based on the ascertained risk indicator. | ||

| 主权项 | 1. A method for assessing cardiac risks based on heart activity data obtained during a recovery stage of an exercise test of a specific patient, comprising: determining a prognostic period of the heart activity data after a time t0 after a peak heart rate of the exercise test; ascertaining a risk indicator based on (a) the heart activity data during the recovery stage only after time t0 and (b) a post-exercise heart rate reserve based on a post-exercise resting heart rate; and providing an assessment of cardiac risk of the specific patient based on the ascertained risk indicator wherein the time t0 is an effective time delay between a protocol defined start of the recovery stage and a subsequent physiological start of the recovery stage after termination of exercise. | ||
