Our manuscript "Importance of the Heart Vector Origin Point Definition for an ECG analysis: The Atherosclerosis Risk in Communities (ARIC) study" is published in the Journal Computers in Biology and Medicine !!! We developed a method to identify the heart vector's origin on vectorcardiogram. • Origin of the heart vector corresponds to an isoelectric TP (or TQ) segment on ECG. • Time-coherent global XYZ beat properly describes cardiac electrophysiology, and improves accuracy and reproducibility of global VCG and ECG measurements (e.g. QRS duration, QT interval). • Time-coherent global XYZ beat improves the predictive accuracy of sudden cardiac death biomarkers.
Dr. Erick Perez-Alday and the Tereshchenko Laboratory presented two abstracts at recent American Heart Association Scientific Sessions in Chicago. Dr. Perez-Alday presented a poster with results of HCM ECGi study, and gave a talk reporting our newly developed algorithm to detect origin of the heart vector on ECG. Results of our study helped to determine an "expiration date" for various ECG metrics. Congratulations, Erick and all team!!!! Great work!!! Both presentations were well received.
