<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Ive been experiencing shortness of breath, sharp chest pain, irregular heartbeat and even involuntary urination. Can you please tell me whats wrong with me?  <response>: Based on your symptoms, its possible that you have paroxysmal supraventricular tachycardia, which is a type of arrhythmia that causes episodes of fast and irregular heartbeats. We need to do further tests to confirm the diagnosis.
