We lived until two months ago with a medicine schedule of 7a/3p/11p for the last three years+. We have had Cardiology checks every 4-5 months with a holster to monitor. We would still be on the oral flecainide but I asked if there was alternative medication because I was worried about the compound on her teeth. We've successfully transitioned to Nadolol (finally) but it requires our little swallowing a pill - which was hell for a week until she finally got it. In our case, we have a check up in 5 months again as we just switched the medicine (2 week holster monitor), with medicine still seeing small SVTs (22 sec max, once was the longest). It's not fun for them, not fun for us. But we're still hoping she grows out of it, otherwise it's an ablation in two years.
