With P waves labeled — Isn't it now much easier to appreciate that the atrial rhythm is quite regular ( with no more than a slight sinus arrhythmia )? P utting I t A ll T ogether : The precise mechanism of today's arrhythmia is complex and difficult to determine. For those with a special interest in cardiac arrhythmias — READ ON! —

DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

While medical trial of an antiarrhythmic agent can at times be undertaken ( assuming the clinician remains at the bedside throughout the process ) — synchronized cardioversion is often favored for treatment of AFib with WPW, given the exceedingly rapid ventricular response with this arrhythmia. What do YOU see?

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?

2] Conduction through the accessory pathway can be intermittent (with different degrees of pre-excitation), and affected by ischemia. 3] So a patient with WPW can have the pattern induced by ischemia, and there is also a report of a patient with pre-existing WPW which was “ablated” by myocardial infarction after an LAD occlusion.[4]

This suggests ischemia of uncertain duration. L addergram I llustration : At this point — I needed to work out, and then draw a laddergram that I could then verify to ensure a plausible mechanism for today's arrhythmia. There is deep, symmetric T wave inversion with a prolonged QTc interval in anterior leads V1,V2,V3.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
