A dynamic Brugada sign due to left anterior descending coronary artery occlusion.

Brugada phenocopies (BrP) include several conditions with a common electrocardiographic (ECG) pattern that are indistinguishable from classical Brugada syndrome (BrS). In this report, we describe two cases of acute myocardial infarction (AMI) presenting as BrP. The majority of cases of BrP in AMI have been reported due to right coronary artery (RCA) occlusion.

Myocardial infarction in a patient with WPW syndrome. Lifting the veil.

Wolf-Parkinson-White syndrome (WPW) syndrome can mimic myocardial infarction (MI) due to the prominent repolarization changes secondary to abnormal myocardial activation by accessory pathway. Rarely these repolarization changes might mask the classical electrocardiographic (ECG) picture of MI and present with atypical ECG features, delaying the diagnosis in the emergency room. We present a case, where the onset of the MI in WPW syndrome was identified based on delta-T wave concordance, and QRS fragmentation.
