ECG Abnormalities_Part 09

Monday, October 18, 2010

A 50 year old male with no past medical history presents to the emergency room with sudden onset severe chest pain. The pain is 10/10, substernal, sharp in nature, worse with deep inspiration, not positional or reproducible, and associated with shortness of breath and dizziness but no excessive sweating , nausea, or vomiting.

His temperature is 37.0, blood pressure 80/40, heart rate 110, respiratory rate is 28. His oxygen saturation is 88% on room air. He appears in mild distress, no jugular venous distension is present, he is tachycardic and regular without any murmurs. His lungs are clear to auscultation. The rest of his exam is normal.

His ECG is given below:

What is the Abnormality in this ECG Strip


ECG ANSWER

The ECG findings include:
1) Sinus tachycardia
2) S1Q3T3 pattern consistent with acute cor pulmonale (acute right ventricular strain) a.k.a. the "McGinn-White sign"

The diagnosis is pulmonary embolism
The patient's clinic scenario of pleuritic chest pain, tachycardia, and hypoxia should raise a high clinical suspicion for pulmonary embolus. Also, his chest pain was sudden onset and severe unlike that of myocardial ischemia. Aortic disection can cause sudden-onset severe chest pain as well, however usually the patient is hypertensive and not necessarily hypoxic.

  20. Pulmonary embolism (clinical manifestation, tachycardia, s1q3t3). It's a serious case as ECG modifications are usually present in severe embolisms.

  41. all the clinical pecture is related 2 pul.empolism(tachycardia,deficulty in breathing.chest pain that related 2 inspiration.low xygen saturation)

     
  42. Anonymous Says:
  43. sinus tachycardia, S1, Q3 and T3 all correlated to the scenario with the conclusion PULMONARY EMBOLISM but there is ST elevation and T wave inversion in V2, V3, isnt it representing SEPTAL MI along with PULMONARY EMBOLISM?
