New app offers training to read EKGs

Can be used on Apple portable devices

An Iowa City software development company is launching an application Friday that will help train medical professions to read basic electrocardiogram (EKG) test results.

Single Sail Software’s Arrhythmia app was developed by Andrew Barr, who has worked with Apple to make the app available for use on iPhone, iPod Touch, and iPad.

Arrhythmia is a free download with four sample rhythms. A single one-time in-app purchase unlocks additional rhythms.

An EKG shows the heart’s electrical activity as line tracings on paper. The peaks and valleys are called waves.

The Arrhythmia app provides the ability to practice identifying basic EKG rhythms as they are simulated across the screen.

Barr, a registered nurse for eight years, said interpreting EKGs is a skill that takes time, practice and refreshing of knowledge.

“A health care professional typically goes through a class,” Barr said. “The training usually is paper-based.

Barr said he began working on the EKG app in December.


“What I do with the app is make the bridge from the end of that kind of class to the hands-on training in a hospital setting. It gives the health care provider an opportunity to see the various rhythms on the fly.

”They can practice reading the different rhythms as they come up on the screen.”

Barr said the user clicks on a rhythm and selects an answer from a list. The app indicates whether their interpretation is correct.

It can be downloaded from the Apple iTunes store without charge and displays four rhythms.

Barr said Single Sail Software revenue will be derived from the one-time in-app purchase that unlocks additional rhythms.

Single Sail Software was founded by Barr in 2010. The company specializes in health care apps for the iPhone, iPod touch and iPad mobile computing devices.
