<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was bitten by a dog and 6 days later, my heart began to have palpitations. This has continued, principally when I am at rest, particularly when I lie on my left side. Very annoying and it makes me feel as if I am not long for this world. I have catastrophic insurance only and I am unemployed, thus going to the ER would send me to the poor house.  <response>: Hi there, Causes of heart palpitations are Hyperthyroidism, Anxiety, Stress, Anemia, Heart Diseases to name a few. Dog bites can cause rabies infection, but this is rarity these days because of immunization but still cannot be ruled out. If the dog was behaving in a strange way it could have carried a rabies virus. Still I do not think your palpitation are due to rabies as its incubation periodtime since infection to the symptoms is 1 to 2 months. There is a classic feature of rabies i.e. HY Chat Doctor. Still you can get a Rabies Vaccination done. Your Palpitations could be from other reasons as indicated above. Thanks
