Heart problems and ttc

Although I’m not ttc yet (I have a 1 year old son and I’d like to wait at least another year) do you think it’s dangerous to get pregnant with heart problems? I have sinus tachycardia (fast heartbeat), occasional premature ectopic complexes (skipped beats), and occasional PVCs (basically an extra heartbeat) I know not everyone is a doctor, and I will be speaking to my doctor about this, I just wanted your guys’ opinions. I have been pregnant before, and my son was smaller (measuring 13th percentile most of my pregnancy, and 29th by the end) and I had to have an ultrasound once a month, then once a week after his belly was measuring a week behind (2 weeks behind my edd)

My son was a surprise, but we eventually want to have at least one more baby
