2023, International Journal of CardiologyMinute Stroke Distance Is a More Reproducible Measurement Than Cardiac Output in the Assessment of Fetal Ventricular Systolic Function
2023, Journal of the American Society of EchocardiographyCitation Excerpt :The range of valve areas is narrower at smaller fetal size and wider at larger fetal sizes, resulting in narrower range of CO at smaller fetal sizes. Prior studies in adults suggest the use of VTI as a surrogate marker of CO independent of gender or body surface area.20 After acute myocardial infarction, VTI obtained before discharge or death stratified risk for both 1-month and 5-year mortality.21
Velocity-Time Integral: A Bedside Echocardiography Technique Finding a Place in the Emergency Department
2022, Journal of Emergency MedicineCitation Excerpt :A quick assessment of the VTI in a hemodynamically unstable patient can provide a useful data point in identifying the underlying etiology. The normal range for VTI is between 17 and 23 cm (3,11). When the VTI falls below these parameters, cardiogenic, obstructive, or hypovolemic shock should be considered (19).
