Leslie had the cardiac cath today. They had to sedate her completely, so right now she is still sleeping. They did not see any blockages or any abnormal pathways in her heart. The doctor that did the cath said he believes the initial incident was caused by the pulmonary embolism, which caused her to stop breathing and her heart to stop. I can see this, but I have trouble believing it is the main cause, just because she went into the arrhythmia during the lumbar puncture, and she has continued to have PVCs (premature ventricular contractions, which is an irregular heart rhythm) throughout her entire hospital stay.
We obviously aren't done, though, we just aren't sure what the next step will be. As of right now, they are leaning more towards her NOT needing a defibrillator, but nothing is set in stone.
