“…A mimicking cause is a pathology different from BrS, still able to induce an acquired STE resembling that of BrS (called Brugada phenocopy), in the absence of any criterion of the Shanghai Brugada Scoring System (including the absence of the genetic defect), and the list of the mimicking causes is the list of causes of right precordial leads STE [26, 116,124,126,127,128]. Hardly ever, the BrS presents with coved-type STE in leads outside V1-V3 [129]. Unlike the R' wave of a genuine RBBB, (featuring a sharp vertex and fast downsloping, followed by convex upwards ST depression and escorted by reciprocal wide S wave in left precordial leads), the J wave of BrS displays a rounded nose, slow downsloping, is followed by the salient convex upwards STE and has no reciprocal S wave [130].…”

As the earliest indirect sign of an acute coronary occlusion arriving against non-operative collateral heart vessels, the unabating ST segment elevation accounts for the acute coronary syndrome asking for mandatory and immediate reperfusion therapy. The geography of the ST segment elevations usually enables one to identify the culprit artery and to guess its likely occlusion site, as pivotal pieces of the necessary vital risk forecasting, along with somehow expected occurring arrhythmias. Aside from the classical ST segment elevation myocardial infarction (STEMI) pattern, a handful of distinctive non-ST elevation appearances of the acute coronary occlusion also need imperative reperfusion therapy, thus qualifying themselves as STEMI equivalents. The early forthcoming of ST elevation during an acute transmural ischaemic episode, as well as the wide availability of the electrocardiogram, make it an invaluable diagnostic tool. Yet many confounding factors are able to limit the diagnostic sensibility of ST elevation (as for example its customary absence in the conventional leads in some cases of circumflex artery occlusion, or the casual mutual cancellation of the transmural ST vectors from opposite ventricular walls), the accuracy of the electrocardiographic localisation of the occlusion site (due to coronary anatomic variants, concomitant new or old coronary lesions elsewhere, previous coronary artery bypass grafts), as well as its specificity for transmural ischaemia (by virtue of a well-known manifold of non-ischaemic causes). While the STEMI patient must be offered undelayed reperfusion therapy, the non-ischaemic ST elevation one should be kept away from the haemorrhagic risk of a useless invasive procedure.
