Insights
The de Winter T-wave, an unusual ECG pattern, can indicate acute myocardial infarction (STEMI) caused by obtuse marginal artery occlusion. Early recognition is crucial for timely reperfusion therapy in STEMI networks.
Area of Science:
- Cardiology
- Emergency Medicine
- Diagnostic Electrocardiography
Background:
- Acute ST-segment elevation myocardial infarction (STEMI) requires rapid diagnosis and intervention.
- The de Winter T-wave is an uncommon electrocardiogram (ECG) finding associated with myocardial ischemia.
Observation:
- A 54-year-old male presented with chest pain and ECG findings suggestive of STEMI, including de Winter T-waves in lateral and inferior leads.
- Emergent coronary angiography identified an occluded obtuse marginal (OM) artery as the culprit lesion.
Findings:
- This case highlights that the de Winter T-wave pattern can be present in acute OM artery occlusion.
- The ECG findings were indicative of a significant coronary artery blockage.
Implications:
- Emergency physicians and STEMI network personnel should be aware of this ECG pattern for prompt diagnosis.
- Recognizing de Winter T-waves in STEMI facilitates urgent angiography and reperfusion, improving patient outcomes.
Abstract:
A 54-year-old man presented to the emergency department with chest pain and electrocardiogram (ECG) changes of acute ST-segment elevation myocardial infarction (STEMI) and junctional ST-depression with tall symmetrical T-waves (de Winter T-wave) in the lateral and inferior leads. Emergent coronary angiography revealed a culprit lesion in the gigantic obtuse marginal artery (OM). This case demonstrates the de Winter T-wave can occur in a patient with an acute occlusion of OM. Emergency physicians, ambulance staff, cardiologists and all involved in STEMI networks should familiarize themselves with this unusual ECG pattern and consider transferring patients for urgent angiography and reperfusion therapy.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
