About EchoLab
EchoLab presents the formulas and algorithms used daily in an adult echocardiography laboratory. Designed by a practicing cardiologist and echocardiographer, EchoLab provides a comprehensive framework for teaching the principles of quantitative echocardiography, or cardiac ultrasound. EchoLab's unique design permits sharing of entered and calculated data between its many formulas, with no need to re-enter data when shifting to a new calculation. Quick Entry views provide immediate access to a wide array of echocardiographic calculations to fuel the Analytic Engine.
Unique to EchoLab among echocardiography applications is the powerful Analytic Engine, which synthesizes results from multiple calculations into a cohesive overview with a comprehensive summary, with integration of ASE/EACVI guidelines. The included companion app for the Apple Watch provides a ready reference when performing or interpreting echocardiograms.
Available with each calculation is a graphical display of the corresponding mathematical equation, along with tips for using the calculation and medical literature references with integrated hyperlinks.
Calculations and analyses include:
• Aortic effective regurgitant orifice area
• Aortic energy loss index
• Aortic flow acceleration time with ratio to left ventricular ejection time
• Aortic prosthetic paravalvular regurgitant extent
• Aortic regurgitant fraction
• Aortic regurgitant jet width, jet area, pressure half-time, and vena contracta
