Sudden VTACH to VFIB - Page 2

it could have been any number of things, tension pneumothorax, PE (PE's can be a PEA, or brady arrest, but also can be v tach)collapsed or ruptured graft, a clot in any of the grafts or coronary arteries, etc.....are they doing an autopsy? Sudden change in K level due to lasix? Calcium and mag both okay? No new meds or withdrawal of antiarryhmics?

agree with trauma lover on possible causes

Was the QT interval long? Was the VT preceded by an R-on-T PVC? Hypoxia or sleep apnea? Were isoenzymes okay following the code?

I'm also interested in whether they are doing an autopsy? To answer your question about whether or not it's common to have someone suddenly go into VT/VF arrest... I wouldn't say it's common, but your patient did have a strong cardiac history and post-op complications.
