How do systolic time intervals vary with changing cycle length in patients with atrial fibrillation and mitral stenosis?
The study demonstrates how systolic time intervals vary with changing cycle length in patients with atrial fibrillation and mitral stenosis.
Answers are grounded in this paper and cite their sources.
Cycle length dependence of systolic time intervals warrants caution in AF; hypothesis-generating for mitral stenosis evaluation.
left ventricular inflow in mitral stenosis might be expected to alter the pattern of ventricular filling during early diastole, features of the left ventricular ejection curves are defined which allow comparison of individual patients. Variation of pre-ejection period and the ratio of pre-ejection period to left ventricular ejection time with changing cycle length for individual patients in atrial fibrillation is also demonstrated.
