For the last two nights I have had heart palpitations, the skipping occurring roughly every 3rd beat, for approximately 3 hours straight. I also have a sore throat, and my sore throat and palpitations seem to have occurred at the same time. I went to the hospital yesterday and they said the palpitations were benign. I am terrified.
Dear Patient, Thank you very much for your question. First do not panic due to this condition. It can make anything worse but not better.  However, you have to visit your family doctor soon. He is the best person who can help you to diagnose and treat your condition because he is very much familiar with your family history, history of other illness you had in the past, medications you used or presently on etc. Therefore, I strongly recommend you to book an appointment and see your family doctor immediately.  Anyway your condition can be a type of Arrhythmia. Skipping heart beats are very much likely to be Extrasystoles which can be either premature atrial or ventricular contractions that you feel as skipping your heart beat. This is a very common condition, however, ECG testing and if necessary 24-hour ECG recording (Holder monitoring) has to be done to make the correct diagnosis.  Sometimes your doctor will direct you to blood tests and ECHO test if needed.  Do not worry. See your family doctor and explain him all your symptoms, and he will come up with solutions. If you have further questions, please let me know. Good luck!
