ECG Findings of WPW Syndrome

Wolff–Parkinson–White syndrome shows a short PR interval (<120 ms), a delta wave (slurred upstroke of QRS), widened QRS complex (>120 ms), and secondary ST–T changes due to abnormal ventricular activation.

STEMI ECG Criteria and Universal Definition of MI

STEMI ECG Criteria and the Universal Definition of Myocardial Infarction: A Complete Guide for Clinicians Early and accurate diagnosis of acute myocardial infarction (AMI) remains the cornerstone of reducing morbidity and mortality in patients presenting with chest pain. Among all forms of acute coronary syndromes (ACS), ST-elevation myocardial infarction (STEMI) represents the most time-sensitive emergency, requiring immediate reperfusion therapy. This article provides a clinically relevant summary of the STEMI ECG criteria and the Universal Definition of Myocardial Infarction (UDMI), based on the latest consensus guidelines from the ESC, ACC, AHA, and WHF. --- 1. Understanding STEMI: Why Accurate ECG Interpretation Matters A 12-lead ECG remains the first and most critical diagnostic test when evaluating suspected myocardial infarction. STEMI is identified when there is evidence of acute coronary artery occlusion, producing transmural ischemia and characteristic ST-segment eleva...

The 1-3-6-12-day rule is a known consensus with graded increase in delay of anticoagulation between 1 and 12 days after onset of ischemic stroke or transient ischemic attack(TIA), according to neurological severity based on European expert opinions. However, this rule might be somewhat later than currently used in a real-world practical setting.
