AV heart block

[Casesmit56]

I am a 29yo male. I've never had any significant health issues. However, when I was 16 years old I was diagnosed with 1st degree atrioventricular heart block. I've never really noticed any symptoms and I understand it is common among active people and athletes. However, my mother was diagnosed with 3rd degree AV heart block and had a pacemaker put in at 33 years old. She was also adopted and we recently discovered her birth family in which these of her biological uncles passed away from heart conditions and one biological sister recently had surgery for a valve issue. Should I be worried? What symptoms should I be aware of to look for? I've never had any fainting spells or anything like that (like my mother did). I wear a heart monitor watch and at night my heart rate dips to 40-44bpm, with the lowest being 37 on one occasion. My typical testing heart rate is between 52 and 58 usually.

Yes, you have a higher risk,based on family history and the age at which your mother was effected.

Symptoms to be worried about are pretty much what you said, dizziness, fainting, feeling faint in addition to an acute loss of your exercise tolerance. Finding yourself fatigued more often or short if breath easier.

Good news is; any further progression is most likely to be just that, a progression. Sudden deterioration into a third degree is unlikely and as long as you get regular check ups with ekg it should be obvious beforehand.
