Medical Editor's Review: This app allows you to view ECG recordings in real time demonstrating a wide range of different cardiac abnormalities. You can also read concise explanations of how each abnormality manifests itself in ECG findings. The ability to view these ECG recordings as often as desired makes this a valuable tool for mastering the nuances of ECG interpretation. Customer reviews: These apps have really been improving since recent updates. They are not designed as standalone tutorials, but rather serve as an excellent and extensive library of realistic example cases that illustrate principles of ECG interpretation, from the simplest to the very complex, and from the common to the very rare. Recent updates have expanded to include basic information on elements of ECG interpretation and cardiac physiology, which has added a new layer of depth to an already great collection of apps. Please, keep up the excellent work!" "A best and easy ecg interpretor which was very useful thanx ecg book...enjoy and try to learn" "Great app for practicing strips!!!
