Sorry about the title, just didn't know how to put it. So, every once in a while I'll feel my heart kinda get tight or heavy or whatever, then right after it'll do what feels like a real heavy heartbeat. Sort of like two beats at once, if you can picture it like that. It'll do that usually 2 or 3 times then it might not happen again for weeks or even months. Another thing my heart will do is it'll get kinda tight or heavy, but then nothing...until I feel slightly lightheaded and dizzy. Not really enough to impair my walking or anything, but it's puzzling to say the least. The light-headedness might last for a minute or two then not happen again for weeks or months. Now I don't know too much about the heart health of my family, but my dad did have a pacemaker put in about 15 years ago when he was in his mid 40's because he was having a condition where his heartrate would drop so low that he would get dizzy and would have to stop working or doing things and sit down. Do heart problems run in the family? I'm only 32, wouldn't I be a bit young to have heart problems?
