Hi, I've just joined Mumsnet and am wondering if anyone has any experience of a baby with SVT (supra ventricular tachycardia). My 8 week old ds ended up in intensive care at 4 weeks with a heartrate of 305bpm. He was only in hospital 2 days and was diagnosed with SVT. We give him meds to regulate his heart twice a day and monitor his heart rate with a stethoscope. I believe this condition is quite rare in babies and was wondering if anyone else has any experience of this. Thank you!
