My daughter thought she might be having seizures, but they only lasted a maximum of about 2 minutes, but 4-10 times a day, at least! Turned out to be PSVT(sudden rapid heart rate...multiple pacemaker/cell locations in the heart firing at different times). During our research, we found many symptoms that seemed to WPW, but I was never able to get a MD to concider the possibility(some primary symptomwas missing). We put a 24 hour Monitor on her to establish this PSVT problem. Went through one ablation and my daughter descided to try less physically invasive drug therapy. Took two to three years to recover completely from the ablation therapy and PSVT. May not be related but the initial possible seizure diagnosis was considered until the monitor established the PSVT. I always wondered if the two could be confused. I actually found a study or review that suggested that at some point this was a frequent mis-diagnosis, but never found any other confirmation, but the question has always lingered.
