METHODS FOR DETECTING AND EVALUATING HEART DISORDERS

摘要

2064887 9119452 PCTABS00008 ECG signals are received from the patient (102), processed (103) to determine deviations from the normal and displayed (104) either as a frequency transformed signal or as a graph of the signal against one of its derivatives in a phase plane plot. The results, depending on the signal and circumstances may be interpreted to obtain information about heart disorders, the degree of drug toxicity or the efficacy of a particular drug. Further, an automatic defibrillator uses the ECG signal received (703) from the patient and processes (704) processing to determine the amount of energy to be discharged into the heart by the shock device (705).
