During a pre-hospital resuscitation, the team achieves ROSC after 18 minutes of VF arrest. The patient's initial post-ROSC 12-lead ECG shows widespread ST-depression with T-wave inversion in leads V1-V6. What does this pattern suggest?AHyperkalaemia causing the ST changesBNormal post-arrest ECG changes requiring no actionCPosterior STEMI - record V7-V9 leadsDAnterior STEMI requiring immediate pPCIEGlobal subendocardial ischaemia or demand ischaemia from the arrest itself - this does NOT necessarily indicate acute coronary occlusion and should be interpreted in the clinical contextCheck my answer
