An Electrocardiographic Clue for Pseudo-myocardial Infarction Due to Arterial Pulse-tapping Artifact: Aslanger's Sign.

Many factors and technical problems may alter the interpretation of electrocardiograms (ECGs). Infrequently, an artifact is considered to be the cause of ST-segment elevation, especially in asymptomatic patients. An important difference between true ST-segment elevation attributable to myocardial infarction and an artifact is that the baseline elevation in an artifact may begin before or after the onset of the QRS complex.

Importance and usage of the CHA2DS2-VASc score in predicting acute stent thrombosis.

Objective: The CHA2DS2-VASc score is used to estimate thromboembolic risk in atrial fibrillation (AF). Its usefulness in predicting outcome in patients after a percutaneous coronary intervention is unknown. We aimed to evaluate the predictive value of the CHA2DS2-VASc score in AF-free patients who have undergone stent implantation.
