Syncope.: Hard to tell. Based on what you have described, it might be wise for you to wear an event recorder (heart monitor) to see if your episodes of syncope correlate with your heart rate and rhythm. Atrial fibrillation with rapid heart rate reduces cardiac output and can contribute to syncope.

Most syncope...: From observational studies, most syncopal episodes are cardiac in origin. It appears that you already have clues on etiology based on history of low BP, dysrhythmias and an EEG which at least by report doesn't show epileptiform activity. It's unclear why you are having an EMG. Follow up with your cardiologist on the current test results for further assessment.
