Hi on Monday my 5year old had two random episodes of tachycardia where his heart was 200bpm. I thought he was gunna pass out cuz he went pale and clammy the first time but was absolutely fine when the second episode happened a few hours later. The hospital have done ecg’s had him on a monitor over night and done his bloods and found nothing! I am waiting on an appointment for him to have an echo and test him for SVT but am having full on melt down at home. I’m scared every time he gets active or upset I’m terrified it will happen again! He had ectopic heart beats when I was pregnant and I had a really difficult pregnancy and thought I would loose him, but ever since I’ve had him I’ve always had this horrible gut feeling that something is seriously wrong and that I’m gunna loose him and don’t know if it’s anxiety or if I should listen too that instinct. I’m sorry it’s a long one I have been having panic attacks in my sleep because of all this and would love to hear from anyone who may have been through something similar? Thanks in advance
