PEP/LVET may aid differentiation of aortic stenosis heart failure; hypothesis-generating from small case series and requires prospective validation.
Does the measurement of systolic time intervals help distinguish congestive heart failure due to aortic stenosis from congestive heart failure caused by other diseases?
The PEP/LVET ratio derived from systolic time intervals may be a useful non-invasive tool to distinguish congestive heart failure caused by aortic stenosis from other etiologies.
