DETECTING WORSENING HEART FAILURE

摘要

A medical system for monitoring a condition of a patient comprises sensors configured to output signals indicative of heart rate, respiration rate and activity level; a memory configured to store an indication of a predetermined threshold zone which is a function of heart rate, respiration rate and activity level. The medical system further comprises s diagnostic module configured to compare the monitored heart rate, respiration rate and activity level to the predetermined threshold zone, and determine the patient is experiencing worsening heart failure when the monitored heart rate, respiration rate and activity level are outside the predetermined threshold zone. The medical system further comprises an alert module configured to issue an alert to indicate that the patient is experiencing worsening heart failure after the diagnostic module determines the patient is experiencing worsening heart failure when the monitored signals are outside the threshold zone.
