Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. As you already know, wolf Parkinson White is a rhythm diaorder.It means you have an axesory pathway that pases the electrical impulses through the heart. So, if you are experiencing palpitation my opinion is that you should seek medical atention.You can present directely to the emergency room when it is posible to do a simple electrocardiogram and watch what is happening whith you rhythm. It is recommended to do so becouse it might be a kind of arythmia than might be controlled whith any medication and so you might be free of this palpitation. Than the long term stategy of this rhythm disorder should be consulted whith your cardiologyst based on other examination like echocarfiography, holter rhythm monitoring, you complains ect. Hope I was helpfull. Best regards, Dr.Ervina.
