Abstract :
Two methods for evaluation of crucial factors describing status of cardiologic patients based on advanced signal processing methods were incorporated into prototype network based clinical decision support system: (a) novel method for chest impedance signal analysis enabling reliable evaluation of central hemodynamics in non-invasive way; (b) method for automatic detection and evaluation of ECG T-wave alternans - predictor of sudden cardiac death. Both methods supplement each other and improve the quality of monitoring of patient status in intensive care unit.
