FREQUENCY DOMAIN ANALYSIS AS RISK PREDICTOR OF SUDDEN CARDIAC DEATH FROM LONG-TIME ECG RECORDINGS

Diego García, César Sánchez, Raúl Alcaraz

Abstract

Sudden Cardiac Death (SCD) is a disease that may not only affect patients with cardiovascular pathologies, but also to apparently healthy patients. Thereby, identification of patients with a high potential of suffering SCD is crucial for their treatment with adequate therapies. To this respect, in the present work, different signal processing tools were applied to surface electrocardiographic (ECG) recordings to develop markers which can clearly differentiate between subjects without cardiovascular pathologies and patients who died of SCD. Precisely, the proposed indexes were the Spectral Concentration (SC) around the main frequency peak, which reached a sensitivity of 100.00% and a specificity of 88.89%, and the Mean Frequency Distance (MFD) between the first spectral peaks, which provided a sensitivity of 95.00% and a specificity of 100.00%.
