Wellens syndrome - ECG case study | MonitorTech.org

This 45-year-old male comes to the emergency department after several days of on again, off again chest pressure. This morning he woke up with 8/10 pain that he describes as “crushing” in nature. It was in the center of his chest but is also causing some discomfort down his arm. It went away after about 30 minutes. It came back just prior to coming to the emergency department. He is currently pain free.

Whelens electrocardiogram result

Past eedical history is unremarkable, although he does have a paternal history of coronary disease. His father had his first MI at the age of 48 years. He currently takes no medication except for a multi vitamin.

Exam: The patient is anxious, although pain free. His skin is warm, pale and slightly diaphoretic. His pulses are all strong and regular.

Pulse is 82. Respirations: 22 Pulse Oximetry: 96% on room air. BP: 148/88

Monitor: Normal sinus rhythm with a rate in the 80’s. His 12-lead ECG is as above.

Are you concerned? What treatment should be started?

This patient’s treatment should include:

  1. Oxygen therapy, admission to the telemetry unit, and a stress test
  2. Aspirin, Emergent Cardiac Catheterization
  3. No immediate treatment is necessary
  4. Nitroglycerin drip and admission to CCU. Cardiac catheterization electively

You suspect that this patient has

  1. A significant coronary stenosis
  2. STEMI
  3. Stable angina
  4. Musculoskeletal pain

If this patient is not properly treated he will probably experience

  1. Inferior wall infarction
  2. Stroke
  3. Anterior wall infarction
  4. There is no way to tell

Discussion: This patient’s immediate treatment should be based on the algorithm for Acute Coronary Syndrome. This should include aspirin (heparin if catheterization is delayed for any reason). He does not require oxygen therapy as he is not short of breath and his oxygen saturation is above 94% on room air.

ECG: This ECG is indicative of Wellen’s Syndrome. The ECG reveals deep T-wave inversion (or biphasic T-waves) in V2 – V4 in a patient who had previous chest pain that has resolved. This is an indication1 of critical proximal LAD disease and requires immediate catheterization and stent placement to avoid infarction. Left untreated, these patients will experience acute anterior wall infarction in the immediate future.

This patient was taken to the catheterization laboratory which revealed the following proximal LAD lesion. A drug-eluting stent was placed resulting in the restoration of normal flow. The patient should do well into the future.
