Is it safe to pick my Grandsons up from school they are 8 and 6yrs, and drive them back to my home once a week (about 6 miles). My Son has asked me to help out which l am happy to do but in my head l am worried what would happen if my heart gave out with such precious cargo on board. l have a normal pacemaker no defib, and AVR. All scans on both are good and my Consultant has never warned me against this lm just a bit worried. Thanks, Sue.
