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 2015 ASE/EACVI cardiac chamber quantification guidelines and 2014 ACC/AHA guidelines for valvular heart disease. Go to www.medicalappware.com/gallery for a full tour of EchoLab in action.

EchoLab presents the formulas and algorithms commonly used in the day-to-day operation of an echocardiography laboratory. Designed by a practicing cardiologist and echocardiographer, EchoLab provides a comprehensive framework for teaching the principles of quantitative echocardiography, or cardiac ultrasound, by demonstrating in detail the inter-relationships between these formulas. EchoLab is unique as an application for echocardiography in its wide scope and with its sharing of entered and calculated data between its many formulas (users do not need to re-enter data when shifting to a new calculation). Six Quick Entry views provide immediate access to a wide array of echocardiographic calculations.

EchoLab also displays all entered and calculated data with an assessment of each variable as normal or abnormal by adult criteria, if relevant. Available with each formula is a graphical display of the corresponding mathematical equation, along with tips for using the calculation and references from the medical literature.

Store output from the Analytic Engine, scientific papers, slideshows, movies, photographs, and schematics in a user-customized library. Send any library file to a colleague as an E-mail attachment with a simple touch.

Included with EchoLab is a companion app for the Apple Watch, providing a ready reference during performance and interpretation of echocardiograms. See what measurements are needed, check reference ranges, and read notes about proper performance of measurements and use of each calculation.

Calculations and analyses included in the application include:

• Aortic effective regurgitant orifice area

Note that EchoLab is a teaching and reference application, not a tool for clinical diagnosis, clinical decision-making, or echocardiography report generation.
