ECG Pro integrates with the Health app now, which enables a feature to replay your own ECG recordings done on your Apple Watch (Only available in ECG enabled regions) The ECG Pro app has proved to be very useful for reference on ECG readings. Everything is interwoven beautifully and it reduces the need to look at many different sources. Over 5m users are using ECG Pro to learn and sharpen electrocardiography knowledge and skills! They are medical students and teachers, primary healthcare providers, physicians, practitioners, and nurses. Join them today to get your ECG knowledge refresh. Medical App Editor's Review: Here is a rich collection of real 12-lead ECG cases you can use to develop your interpretation skills. Each case is identified with a brief description (e.g., "Male 73 y/o, HR 158; Ectopic arrhythmia - atrial tachycardia with intraventricular aberrant conduction..."). Select a case and you can choose either Play mode, which shows you the ECG telemetry as you'd see it on a monitor in real-time, with beeps for heartbeats, or Read mode, which gives you the printed ECG tracing to interpret. You can choose cases by category or search for them by name. You can also bookmark cases and return to them later. For students and practitioners who wish to strengthen their ECG-reading capabilities, this app would seem justified, because ECG Cases gives you an effective way to immerse yourself in a wide range of ECG patterns and interact with them as if these were your own patients.
