just a note: pvc's are common and often symptoms of a benign cause. A very large percentage of the population experience pvc's or other arrhythmias on a regular basis. It itself, the presence of pvc's or some other arrhythmia and no treatment is not evidence of negligence.
The entire ER history will have to be studied to determine if the symptoms and findings at the time indicated some other treatment be taken at the time. The fact that she was given a stress ECG while at the hospital would tend to indicate there were no findings of much of anything at the time. You don't have a person in cardiac distress perform a stress ecg. It is used as a tool to cause problems to surface that are not otherwise obvious.
