I have been diagnosed with Wolff Parkinson White syndrome. Went in for an ablation but he couldn't continue after 4 burns as I went in to AFib and he couldn't map the pathways. Long story short I have to go back and do it all again.
He discharged me with a prescription for 180 mg of verapamil and if that didn't help my SVT then he said get GP to up the dose to 240mg. Well I waited a week and it didn't work, so I started today on 240mg SR. my question is How long does it usually take to work as my heart is hammering like a dwarf mining for ore and I am getting mighty sick of it.
