The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient. The Initial ECG in Today's Case: As per Dr. Meyers — the initial ECG in today's case shows sinus tachycardia with bifascicular block ( = RBBB/LAHB ).

Here was his ED ECG: There is sinus tachycardia (rate about 114) with nonspecific ST-T abnormalities. Later, he underwent a formal echocardiogram: Very severe left ventricular enlargement (LVED diameter 7.4 An ECG was recorded: This shows a regular narrow complex tachycardia at a rate of about 160. C (99 °F), Resp (!)

We can see enough to make out that the rhythm is sinus tachycardia. Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW.

See this case: what do you think the echocardiogram shows in this case? With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ). The patient was placed on telemetry.

An echocardiogram was done. Sinus Tachycardia ( common in any trauma patient. ). Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). Is there also Brugada? Here is the result: The estimated left ventricular ejection fraction is 50 %. Right ventricular prominence.
