Mercifully my heart health is pretty good, just my electrics have gone for a bit of a walk!! I am virtually symptom free, so no nasty palpitations and I don't think I have had any tachycardia in more than 2 years so beta blockers and blood thinners are doing the job. Protects me from DVT on long flights too. There's got to be a positive side! I joined a gym a year or so after diagnosis - I lost weight during treatment and wanted to keep it off so it's been a good investment. Hope you keep well too.
