Major research preoccupation in the non-invasive arrhythmic risk assessment. My findings led to demonstration of the usefulness of the ECG Tpeak-end interval and its derivatives as markers of arrhythmogeneicity in hypertensive heart disease, participated in a better characterization of the electro-mechanical physiological correlations, suggested the potential usefulness of novel ECG and echo markers for assessment and monitoring of cardiotoxicity of ADT used for prostate cancer.
