They had already cardioverted at 120 J, then 200 J, which resulted in the following: Ventricular Tachycardia They then cardioverted at 200 J which r esulted in the same narrow complex rhythm shown above, at 185 beats per minute. This would treat both SVT or sinus tachycardia. I suggested esmolol if the heart rate did not improve.

Notice there is tachycardia. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. In this case, the patient had failed to take his atenolol in the AM and was having reflex tachycardia in addition to ACS. But we are now concerned with the precordial leads. BP was 160/100.

There is sinus tachycardia (do not be fooled into thinking this is VT or another wide complex tachycardia!) Primary angioplasty in acute myocardial infarction with right bundle branch block: should new onset right bundle branch block be added to future guidelines as an indication for reperfusion therapy?

This point is particularly relevant regarding ECG #2 — because sinus tachycardia is seen on this earlier ECG. In addition — there were more prominent anteroseptal forces on this earlier tracing ( ie, in the form of an R wave = S wave in lead V1, with similar-looking equiphasic QRS complexes in leads V2-thru-V5 ).

NOTE: As discussed in detail in ECG Blog #108 — " A IVR" is an "enhanced" ventricular ectopic rhythm that occurs faster than the intrinsic ventricular escape rate ( which is typically between 20-40/minute ) — but slower than hemodynamically significant Ventricular Tachycardia ( ie, VT at rates >130-140/minute ).

INTERVENTION * Successful angioplasty and stenting (drug eluting) of the mid LAD * Successful angioplasty of the ostial 1st diagonal Learning points: 1. That said, against acute PE — is the inconstancy of this patient's symptoms — the lack of tachycardia — and the lack of any other ECG signs of acute RV strain.

Here is another proven left main occlusion in a young woman who presented with sudden pulmonary edema, had this ECG recorded, then arrested and was resuscitated after 30 minutes of CPR: This has sinus tachycardia with RBBB and LAFB, and STE in V2-V6 as well as I, aVL This pattern could just as easily be seen in LAD occlusion.
