He was rushed by residents into our criticalcare room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. He had this ECG recorded.
There is a regular wide complex tachycardia. I brought the patient to the criticalcare area and told the providers I thought it was atrial flutter with 2:1 AV conduction, but there is an outside chance that it is VT. Remember : Adenosine is safe in Regular Wide Complex Tachycardia. If it is VT, there will be no effect.
So I immediately left the room to get an ultrasound machine. While calling for some help and arranging to have her transported to our criticalcare zone, I got this quick ultrasound which confirmed my suspicion: This quick view was all I was able to obtain in the circumstances.
Despite otherwise normal vital signs, she was appropriately triaged to the criticalcare area of the ED. She was awake, alert, well perfused, with normal mental status and overall unremarkable physical exam except for a regular tachycardia, possible rales at both bases, some mild RUQ abdominal tenderness. What is the Diagnosis?
Colin is an emergency medicine resident beginning his criticalcare fellowship in the summer with a strong interest in the role of ECG in criticalcare and OMI. We can see enough to make out that the rhythm is sinus tachycardia. Written by Colin Jenkins. Edits by Willy Frick.
Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades. Crit Care Med. Setting: Multidisciplinary criticalcare unit. He was managed medically with Clopidogrel.
Although the shock is no doubt partly a result of poor pump function, with low stroke volume, especially of the RV, it should be compensated for by tachycardia. They did not have an ultrasound on the ambulance (some local crews are starting to utilize POC limited US in our service areas). This is a perfect indication for atropine.
She had this ECG recorded: Obvious massive anterior STEMI She was quickly brought to the criticalcare area and the cath lab was activated. The blood pressure was 170/100 in the criticalcare area. And almost all of them could be detected by bedside ultrasound. Ultrasound Med. Her initial BP was 203/124.
