I also had a pacemaker placed in my 30s for fainting due to low blood pressure and low pulse. I have had difficulty finding others like myself. Would your friend be interested in discussing her situation? I have adjusted well to the pacemaker but still have occasional lightheadedness but no fainting. I am intersted in whether her symptoms have resolved. I, too, am very active but my doctors did not allow me to continue doing martial arts, as they are concerned about damage to the pacemaker leads. I would like to ask her how she has been able to contiue doing martial arts and had she had any issues.
