Point-of-care ultrasound (POCUS) as the keystone investigation in undifferentiated dyspnoea.

Dyspnoea is defined as a subjective perception of laboured breathing. It is a common cause of access to the emergency department (ED), it has a high rate of intensive care unit admission and a high mortality.

Emergency physician accuracy in interpreting electrocardiograms with potential ST-segment elevation myocardial infarction: Is it enough?

Background: Electrocardiogram (ECG) interpretation is widely performed by emergency physicians. We aimed to determine the accuracy of interpretation of potential ST-segment elevation myocardial infarction (STEMI) ECGs by emergency physicians.

Methods: Thirty-six ECGs resulted in putative STEMI diagnoses were selected.
