This was first realised by Schroder and colleagues, who performed very elegant studies in the 1990s, which demonstrated that the sum of the degree of ST elevation was prognostic of outcomes.2 More importantly, they also found that the proportion of ST segment resolution was also associated with ...

Clinicians need to have an understanding of the ECG changes associated with bundle branch blocks in order to distinguish between these changes and those associated with ST-segment elevation myocardial infarction (STEMI). 展开 关键词: Acute Coronary Syndrome Bundle-Branch Block Early Diagnosis ...
Identifying an acute myocardial infarction on the 12-lead ECG is the most important thing you can learn in ECG interpretation. Time is muscle when treating heart attacks. Missing a ST segment elevation MI on the ECG can lead to bad patient outcomes. It’s just not good. So let’s go...
