Bradycardia Cardiac Arrest Pulmonary

Bedside cardiac ultrasound showed moderately decreased LV function. 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. See this post: How a pause can cause cardiac arrest 2.

This false electrical capture may have made cardiac arrest recognition difficult, and the re-arrest may have gone unrecognized for an unknown amount of time. The receiving staff suspects pulmonary embolism due to S1Q3T3 on the ECG and administers TPA. On ED arrival ROSC is achieved.

Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. mEq/L, from 1.9 mg/dL [1.03 0.16

In any case, there is bradycardia. It makes pulmonary embolism (PE) very likely. The small LV implies very low LV filling pressures, which implies low pulmonary venous pressure. First, what kind of arrest was this? It was a PEA or bradyasystolic arrest , not a shockable rhythm. No shock was ever delivered.

There is sinus bradycardia with one PVC. There is "Shark Fin morphology" I saw this and thought for certain that this was going to be an LAD or left main occlusion as etiology of arrest, and etiology of profound ST Elevation in I, II, aVL, and V3-V6, and ST depression in III, V1 and V2. pulmonary embolism, sepsis, etc.),

If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise. The estimated pulmonary artery systolic pressure is 37 mmHg + RA pressure. Normal estimated left ventricular ejection fraction lower limits of normal.

The patient was unconscious BEFORE the cardiac arrest, at the same time that she had strong pulses. Therefore, cardiac arrest is NOT the etiology of the coma. she had severe pulmonary edema.
