The ECG does not show any definite signs of ischemia. Uncontrolled coronary spasm may be associated with serious arrhythmias , including cardiac arrest ( Looi et al — Postgrad Med, 2012 ; Tan et al — Eur Heart J Case Rep, 2018 ; Chevalier et al — JACC, 1998 ; Rodriguez-Manero — EP Europace, 2018 ).

Finally, do a coronary angiogram Possible alternative to pacing is to give a beta-1 agonist to increase heart rate. Use Lidocaine instead (lidocaine prevents the PVCs which cause R on T, and does not prolong the QT.) Discontinue all QT proloning medications, including azithromycin 6. Dobutamine is an acceptable alternative.

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. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

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. CT coronary angiogram — No obstructive coronary disease. CT coronary angiogram showed no obstructive coronary disease.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

The possibility of an ischemic cause of the ventricular arrhythmia has to be considered! That said there were no clinical symptoms or ECG findings suggestive of ongoing ischemia. A workup was undertaken in search of a cause of the patient's ventricular arrhythmia. CT coronary angiogram showed a hypoplastic RCA and dominant LCx.
