VitalSim Rhythm — ECG Trainer

VitalSim Rhythm now fits iPhone Duo and smaller iPhones, and it has a new app icon. • iPhone Duo: the app fits the outer display when folded and the larger inner display when open. • Analyze and Compare now fit the screen on iPhone, including smaller models. When there is more to read, the screen scrolls instead of cutting it off. • Rows of controls show a soft fade at the edge where more controls scroll into view. • Compare stacks its two strips on screens too narrow to show them side by side, such as the iPhone Duo inner display held upright. • The caliper A and B tags now sit inside the strip, and you can drag a caliper by its tag. • Glossary search has a Done button that closes the keyboard and keeps your search. • A new app icon. No rhythms, lessons, or teaching content changed in this update. VitalSim Rhythm remains education software and is not a medical device.

This update improves measurement accuracy across every rhythm strip and corrects several teaching explanations. - ECG intervals (QT, PR, QRS) are now measured from where each strip actually places them, and readings a strip cannot reliably support are labeled as such rather than graded as correct or incorrect. - Fixed a timing issue with the atrial flutter rate control and with the PR interval marker on paced rhythms. - Corrected 12-lead report values for rhythms with no organized heart rate or repolarization. - Revised several teaching explanations for accuracy, reviewed by a nurse educator.
