Hello, The continuous loop recorder will itself Register all the events whether you feel or episode s which may go unnoticed , so do not worry about that, whereas in some event recorder you may have to press the record button to store that episode, do verify with the technician about the machine used. Just I would like to point about that shortness of breath, dizziness though can be explained by some arrhythmia happening in spite of flecanamide, where changing dose or adding / substitution may be the treatment post review of loop recoder. However all the symptoms describe are known side effects of flecanamide itself so do consult your doctor for the same. Regards Dr Priyank Mody
