Hi, I took my resting heart rate for the first time in months and it was 41. I do not exercise that often and have been having problems with consistent dizziness, headaches, sinus problems, and deteriorating vision. I have mild IBS symptoms as well as fatigue, nausea, weakness, memory loss, poor concentration, and very poor circulation in general. My doctor referred me to an allergist and a neurologist but it seems like I should be seeing a cardiologist. Should I be worried? I have had these symptoms for months now but I only recently realized that my heart rate is low. Could bradycardia cause all of these symptoms?
