<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I am a 21-year-old female. For the last day or two I have been feeling a little faint and have been experiencing mild but noticeable heart palpitations. I am a healthy weight, my diet is good, I ensure I am drinking plenty of fluids and have no serious health issues. The only thing that may be of note is a diagnosis of bradycardia with a BPM of 56 and consequent to this a slightly lower than normal blood pressure rate. Could these be contributing to my recent feelings of faintness and awareness of my heart beating?  <response>: Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms may be related to orthostatic hypotension. These values of heart rate are not very low, but a persistent bradycardia could also explain palpitations escaped beats during bradycardia and fainting. I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x-ray study and some blood lab tests complete blood count, fasting glucose, kidney and liver function tests, blood electrolytes, etc.. A head up tilt test is necessary to rule inout possible orthostatic hypotension. An ambulatory 24-48 hours monitoring, and a cardiac ultrasound are necessary if suspicions of a persistent bradycardia are raised. Hope to have been helpful! Best regards,
