Systolic time intervals provide a validated, quantitative noninvasive technique for assessing left ventricular performance in various cardiovascular disorders.
Systolic time intervals provide a validated, noninvasive method for assessing left ventricular performance, though further research is needed to optimize their clinical utility.
The theoretical basis for the use of the systolic time intervals has been largely established. The method has been validated by direct measures from within the circulatory system. Standards for equipment and technique have been defined. Numerous clinical studies have demonstrated the value of this quantitative noninvasive technique for assessing left ventricular performance. At present there is need for further studies of the clinical usefulness of the systolic time intervals to improve both diagnosis and therapy of various cardiovascular disorders.
Lewis et al. (1977) conducted a review in Cardiovascular disorders. Systolic time intervals was evaluated. Systolic time intervals provide a validated, quantitative noninvasive technique for assessing left ventricular performance in various cardiovascular disorders.
