CT of the chest showed no pulmonary embolism but bibasilar infiltrates. Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. Place temporary pacemaker 3. She was intubated. Bedside cardiac ultrasound showed moderately decreased LV function. The plan: 1.

This middle-aged patient presented with SOB, weakness, and mild pulmonary edema. There are 3 etiologies I always think of with bradycardia and AV block: 1. She had a permanent pacemaker implanted. She previously had Atrial fibrillation with LBBB. Here is her ED ECG: Does this reveal the etiology of her symptoms? Hyperkalemia.

I’d guess the overall rhythm is sinus, perhaps with a wandering atrial pacemaker and very frequent ventricular ectopy with multiple couplets. Perhaps the patient has pulmonary hypertension and/or tricuspid regurgitation? In the meantime, a pacemaker may be needed. =

This is demonstrated ( Figure 5 ) by the gap in arrows at the bottom of the strip, signifying that the demand pacemaker has recognized an underlying rhythm (in this case, artifact from a moving ambulance). The artifact fools the pacemaker into thinking the rhythm is native.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
