Phonocardiography and Auscultation Techniques

For proper distribution of preventative resources, a more robust method of cardiac risk stratification should be encouraged in addition to merely reduced ejection fraction. To this end, the QRS‐T angle, an electrocardiogram‐derived measure of the difference in mean vectors of depolarization and repolarization, has been found associated with sudden cardiac death and other mortal and morbid outcomes in multiple observational studies over the past decade. The use of both frontal and spatial QRS‐T angle in the prediction of future cardiac events including sudden cardiac death, all‐cause mortality, and further cardiac morbidity is reviewed here.
