There are several distinct ECG patterns in pulmonary embolism

A 36 yo male presents to the emergency department with sharp central chest pain and shortness of breath. He works as a truck driver. He has no past medical history, is on no medications and normally very well, with no significant family history.

An ECG is handed to you. What is the diagnosis? (answer below ECG)

                                                                                                                          ECG from

Pick an Answer:
(a)   Acute ischaemic changes
(b)   SVT
(c)   Pulmonary Embolism
(d)   Raised Intracranial Pressure
(e)   Non-ST Elevation Myocardial Infarction

Using the ECG in 20 Seconds Approach: This ECG shows a sinus tachycardia of rate of 120bpm. The p waves are upright in II and inverted in aVR, the QRS complexes appear normal. The axis is rightward. In the ST-T segments the obvious abnormality is inverted T waves in leads III, aVF, V1-5. In terms of intervals there appears to be a prolonged QT and there are no pacing spikes.

Interpretation: This is a classic ECG of a submassive pulmonary embolism.

Answer is (c)

I speak about this in the video below. I will also spend quite some time covering ECG’s at the  Cardiac Bootcamp. I hope to challenge you there, please bring your own ECG’s and challenge me and let us see how the system I teach in ECG in 20 seconds will help you make the diagnosis!
