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
