INTRODUCTION Takotsubo cardiomyopathy also known as transient left ventricular apical ballooning, stress-induced cardiomyopathy can present with retrosternal chest pain with EKG changes that can mimic a myocardial infraction. CASE PRESENTATION We present a 68 female with sudden onset retrosternal squeezing chest pain with positive cardiac enzymes and EKG changes suggestive of acute ST-elevati...

Order exercise stress testing without imaging for patients with a low to intermediate probability of coronary artery disease (CAD), unless preexisting electrocardiographic (EKG) changes would render such a test nondiagnostic. Order stress testing with imaging for patients with preexisting EKG changes and/or a high probability of CAD. Do not use stress testing to screen asymptomatic patients for...

Step-stair and banding artifacts may result from irregular ventricular rhythm caused by atrial fibrillation or premature ectopic ventricular contractions. In the case reported here, severe banding and misalignment artifacts occurred due to electrocardiographic noise mimicking ectopic beats. Severe EKG noise or pseudo-ectopic beats may cause rare but serious artifacts during cardiac-CT acquisiti...

Besides entity-centric knowledge, usually organized as Knowledge Graph (KG), events are also an essential kind of knowledge in the world, which trigger spring up event-centric representation form like Event KG (EKG). It plays increasingly important role many downstream applications, such search, question-answering, recommendation, financial quantitative investments, and text generation. This pa...
