My name is Evan and I am a 17 year old with an over active sinus node and wpw. I was told my wpw doesnt appear to be causing my problems but I have been unable to maintain a normal life for ten months. I began having fatige, malaise and was unable to even survive a normal day without episodes of palpitations, loss of balance and weakness that would last for anywhere from five to thirty minutes. I was put on a 24 hour recorder holter and a 30 day event holter and was put on (cardiozem?) but was given the cheaper generic diltiazem 240mg cd once daily. after the first week I was removed from it because I was suffering almost every single side effect possible. what can I do to get my life back and complete my last year of High school.
