A 60-something woman presented after a witnessed cardiac arrest. This is commonly found after epinephrine for cardiac arrest, but could have been pre-existing and a possible contributing factor to cardiac arrest. Final Diagnosis: Cardiac Arrest due to Torsades from long QT of unknown etiology.

See this post: How a pause can cause cardiac arrest 2. Place temporary pacemaker 3. It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. The plan: 1.

There is no definite evidence of acute ischemia. (ie, Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( Some residual ischemia in the infarct border might still be present. Both episodes are initiated by an "R-on-T" phenomenon.

Cardiac arrest Cardiac arrest is a medical emergency in which the heart stops pumping blood to the body. Electrocardiogram, echocardiogram, and some other tests are done for patients with cardiac arrest. If the vital organs do not get their blood supply back quickly, it can lead to death.

My Immediate Impression — was that this elderly woman with a several week history of symptoms would most likely leave the hospital with a pacemaker. This suggests ischemia of uncertain duration. Unfortunately, before this could be accomplished — the patient went into cardiac arrest. A permanent pacemaker was placed.

My thoughts were the following: ECGs #1 and #2 showed a completely unreliable sinus pacemaker, with presumed high-grade 2nd-degree AV block — and frequent resultant pauses of over 2 seconds ( that would have been even longer had it not been for intermittent relief from the atrial escape focus ). What Does this All Mean?
