<s>[INST] I have a heart condition called Wolff-Parkingson-White and I occasionally get palpitations. Currently, Ive had one for about twenty minutes (the palpitation has decreased but its still there) and I was extremely faint and feel as if I am about to pass out. What should I do? Should I wait it out? I cannot get in touch with my doctor and dont know if I should go to the hospital. Im not sure what to do. [/INST] Hello and thank you for using Chat Doctor. 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 disorder. It means you have an theory pathway that cases the electrical impulses through the heart. So, if you are experiencing palpitation my opinion is that you should seek medical attention. You can present directly to the emergency room when it is possible to do a simple electrocardiogram and watch what is happening with you rhythm. It is recommended to do so because it might be a kind of arrhythmia than might be controlled with any medication and so you might be free of this palpitation.Then the long term strategy of this rhythm disorder should be consulted with your cardiologist based on other examination like echocardiography, holder rhythm monitoring, you complain ect. Hope I was helpful. Best regards, Chat Doctor.  </s>
