Diffuse ST segment depression from hypothermia

Diffuse ST segment depression from hypothermia

Hypothermia is known to cause specific electrocardiographic (EKG) changes such as Osborne waves and bradycardia. We report diffuse ST segment depression, an atypical EKG change, in a patient with a core temperature of 29.4°C (85°F). This patient had no previous cardiovascular pathology, and his EKG changes resolved gradually with aggressive warming. We also discuss the pathophysiology and clini...

Ibuprofen-induced Kounis syndrome with diffuse ST segment depression and atrial fibrillation

Typical pericarditis ECG findings after falling from height. The PR segment depression or ST segment elevation?

Acute pericarditis (AP) following blunt thoracic trauma is rare and difficult to diagnosis. A 43-year-old man with offered to the emergency department (ED) after falling from height before a week ago. The ECG performed in the ED was abnormal, ECG revealed PR segment depression in leads DII, DIII, aVF, and V3-6 and a preliminary diagnosis of acute inferolateral STEMI was presumed. Patients have ...

Resolution of ST-segment depression: A new prognostic marker in ST-segment elevation myocardial infarction.

AIMS To evaluate the prognostic impact of ST depression resolution among patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI in the Assessment of Pexelizumab in Acute Myocardial Infarction (APEX-AMI) trial. METHODS AND RESULTS In this study, 4729 of 5745 patients had analysable ECGs demonstrating concomitant ST-segment depression. Resolution of summation op...

Extent of ST-segment depression and cardiac events in non-ST-segment elevation acute coronary syndromes.

AIMS We sought to determine whether the extent of myocardial ischaemia on the admission electrocardiogram (ECG) has independent predictive value for short-term risk stratification of patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS). Although the presence of ischaemic ECG changes on admission has been shown to predict outcome, the relationship between the extent of ECG ...
