What causes chest pains, shortness of breathe, fatigue and light headiness?
Patient: My resting heart rate has been as low as 28 and usually in the 30s. I havent been very active in almost 20 months and been to the cardiologist before. I have bicuspid aortic but they said it was minor and that I'm fine. I suffer from chest pains, shortness of breathe, fatigue, light headiness, and the occasional fainting. Any ideas what might be wrong and why all the test have came back negative? Doctor: A resting heart rate of 28 is quite low. Your symptoms may be due to sick sinus syndrome in which the physiological pacemaker ( sino atrial node) is  diseased. I would suggest you get a 24 hour holter monitoring done. The cause for such a low heart rate needs to be evaluated. You may also need a permanent pacemaker in the future.
