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!!! Helps with my new nursing career!!!" "Great for anyone learning how to interpret EKG rhythms. I'm a paramedic student and I've greatly benefitted from this app." "I'm a nursing student and our school has poor lecturers so we are teaching ourselves everything. This has helped immensely in my advanced med surg class." ======================================================== ECG Books is a large database of ECG abnormality. It provides 1000+ abnormal ECG cases from real world patients to help illustrate the most important ECG findings. Each book talks about one finding, with detailed information including Causes / Characteristics / Signs / Diagnosis / Treatment The 1000+ abnormal ECG cases are provided in 2 modes: Movie mode and Report mode [Movie Mode] You play each case like watching it on monitor with beep sound of each heartbeat.

Test and improve your ECG interpreting skills with 1000+ samples in static images, and real-time monitor. [What users say about us] "Using this as a study guide for my paramedic. It's a good way to look at the whole picture and put your interpretation skills to the test." "This collection of ECGs designed as realtime display is an essential app for every medical practitioner." "This app is great for anyone learning how to read an EKG" "Professional ecg app with nice monitor display" "Awesome app!!! Worth the download and perfect for studying!" The app is very challenging because it uses REAL patients' ECG recordings, and many of them are complicated with multiple diseases involved. The test need you to pick all interpretations, to get a 3-star rate. Wrong picks will buzz your iPhone / iPad and give you a minus score. [Note] 1) All cases are stored in raw data (sample rate is 500 points per second), not static images, so you can look into very detailed waves in pixels 2) You should already have basic knowledge of ECG interpretation, and you use the cases to build a solid cardiology foundation [Findings Covered] Atrial Flutter Atrial Fibrillation Ventricular Fibrillation Escape Beat PAC (Premature Atrial Contruction) PAC Bigeminy PAC Trigeminy PVC (Premature Ventricular Contruction) PVC Bigeminy PVC Trigeminy Supraventricular Tachycardia Ventricular Tachycardia Ventricular Escape Rhythm Ventricular Rhythm QT Prolongation Short QT High T ST Elevation S1,S2,S3 Pattern High Voltage Positive T in V1 Ventricular Hypertrophy LVH Left / Right Atrial Enlargement Left Ventricular Hypertrophy Left Atrial Overload Short PR Interval WPW Syndrome Suspect WPW Syndrome AV Block I (Wenckebach / Mobitz) 2:1 AV Block Complete AV Block Artificial Pacemaker Rhythm(A / V / D) RSR' Pattern IRBBB (Incomplete Right Bundle Branch Block) IVCD (Intraventricular Conduction Block) CRBBB (Complete Right Bundle Branch Block) CLBBB (Complete Left Bundle Branch Block) ICLBBB (Incomplete Left Bundle Branch Block) LAH (Left Anterior Hemi Block) LPH (Left Posterior Hemi Block) BBBB (Bifascicular Bundle Block) TBBB (Trifascicular Bundle Block) Flat T Negative T ST-T Abnormality Premature repolarization Syndrome Poor R Progression Abnormal Q wave Subendcardial Infarction Possible Anterior Infarction Anterior Infarction Anteroseptal Infarction Possible Lateral Infarction Lateral Infarction Inferior Infarction Possible High-Post Infarction Sinus Rhythm Coronary Sinus Rhythm AV Junctional Rhythm AV Dissociation Marked Sinus Bradycardia Sinus Bradycardia Sinus Tachycardia Tachycardia Bradycardia Extreme Tachycardia Extreme Bradycardia Sinus Arrhythmia
