The Pulsebit-EX scans for multiple arrhythmia patterns. It stores history for two users. It allows you to measure with your palms or with double leads. Use email or download/print to share reports with your doctor. The software is very detailed and is free. If you are never going to use the electrical leads, you could use the Pulsebit as a handheld monitor, or get the KardiaMobile, which is an excellent choice as well.
