Research Seminar, Ms F. El-Hamad — Power contribution analysis of QT interval variability and muscle sympathetic nerve activity

 

Abstract:

Increased sympathetic nervous system activity contributes to the development and progression of cardiovascular disease. Therefore, quantifying the level of sympathetic outflow directed at the heart maybe of diagnostic interest in clinical as well as nonclinical contexts. Beat-to-beat variability of the QT interval, measured from ECG recordings, is sought to provide an indirect non-invasive measure of sympathetic nerve activity, but a formal quantification of this relationship has not been provided. Cardiac sympathetic activity is hard to measure and involves an invasive procedure that can only be performed in animals. However, muscle sympathetic nerve aFactivity can be measure non-invasively and has been suggested as a surrogate for overall sympathetic activity levels.  In this seminar I will present a study in which we investigate the relationship between QT and muscle sympathetic verve activity using power contribution analysis.
