Finally, do a coronary angiogram Possible alternative to pacing is to give a beta-1 agonist to increase heart rate. Even with tachycardia and a paced QRS duration of ~0.16 Use Lidocaine instead (lidocaine prevents the PVCs which cause R on T, and does not prolong the QT.) Dobutamine is an acceptable alternative.

The finding of all negative QRS complexes in leads V3-thru- V6 therefore strongly suggests that the arrhythmia-associated impulse is not traveling over an AP ( Steurer et al — Clin. Given the rapid rate of the tachycardia and the amorphous shape of the QRS — the decision was made to sedate the patient and cardiovert. No sign of ARVC.

A coronary angiogram was done that did not show significant coronary artery disease. Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ).

We investigated the incidence of an acutely occluded coronary in patients presenting with STE-aVR with multi-lead ST depression. All electrocardiograms (ECGs) and coronary angiograms were blindly analyzed by experienced cardiologists. A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ).

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. 3) Anemia, or poisons of hemoglobin such as methemoglobin or CO 4) Fixed coronary stenosis that limits flow.

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). The possibility of an ischemic cause of the ventricular arrhythmia has to be considered! A workup was undertaken in search of a cause of the patient's ventricular arrhythmia. No PVCs are seen.
