Correlation of Invasive Measures of Cardiac Function with Expressions Derived from Systolic Time Inup defined a range of values for the STI in normal individuals and showed that patients with left ventricular failure had abnormal STI (2). Many studies have defined the effect of various cardiac lesions, positive and negative inotropic drugs, anesthetics, and other manipulations on STI (3, 4, 5).

A Computer Program for Evaluating Systolic Time Intervals at Rest and During Intervention Tests,r heart rate (HR) corrections (5). Automated data processing allows the standardization of measurements and the evaluation of large groups of patients. This report describes a method of recording and evaluating STIs by digital computer.

Measurement and Interpretation of Pulse Pressure and Flow During Systole,mpared with the output of the model. An agreement between model and system output is reached by adjusting the parameters of the model. Even a highly empirical procedure like the evaluation of systolic time intervals (STI) can be described as this kind of parameter estimation process.

Assessment of Myocardial Contractility by Using the Systolic Time Intervals,eases which secondarily affect the heart muscle. Assessment of the myocardium is, therefore, essential for the clinician. For investigative purposes it is, of course, also essential for the epidemiologist, pharmacologist, and physiologist.

Noninvasive Score for Evaluation of Left Ventricular Function,ular function; for example, a correlation coefficient of . = 0.85 was found for the ratio, of pre-ejection period (PEP)/left ventricular ejection time (LVET), plotted against the left ventricular ejection fraction (LVEF). These results could not be confirmed in later studies by others (2–4). So good

Use of Systolic Time Intervals in the Operating Room,ative cardiovascular monitoring. Five years of experience with an experimental, intraoperative, computerized STI-monitoring system allows us to answer some questions related to the use of STI monitoring in the operating room.

Hemodynamic Response to Bicycle Exercise Correlated to Pre-ejection Index,ng physical exercise. Only during exercise are hemodynamic parameters such as arterial blood pressure, pulmonary arterial end-diastolic pressure (PAEDP), cardiac index (CI), and spiroergometric data measurable as clear signs of possible heart failure.
