WebConclusions: In patients presenting with chest pain, ST-segment depression at the J-point with upsloping ST-segments and tall, symmetrical T-waves in the precordial leads of the 12-lead ECG signifies proximal LAD artery occlusion. It is important for cardiologists and emergency care physicians to recognise this distinct ECG pattern, so they can ... WebNov 26, 2024 · The T wave morphology is identical to patients who reperfuse after a successful PCI. · If the artery remains open, the T waves evolve over time from biphasic to deeply inverted. · The coronary perfusion is unstable, however, and the LAD can re-occlude at any time. If this happens, the first sign on the ECG is an apparent normalisation of the ...

WebDec 8, 2024 · Notches and nipples can occur when P waves are embedded in the T waves. Here is an example of junctional escape rhythm with retrograde conduction (red highlight). The retrograde P waves are inverted (red highlight) and the junctional cycle slower than the sinus cycle. A junctional rhythm without retrograde conduction may also have P waves ...
