my heart or chest starts to to palpatate and I get dizzy and light headed. This will happen during a normal conversation and sometimes I have to stop talking or I feel like I will pass out. This started about 2 months ago but went away for a while. Over the last week it has been happening again. Even when I am just sitting around it happens from time to time. I am 51 years old and although over weight I am pretty active. This is driving me nuts
HelloThanks for posting at Chat Doctor. Your symptoms do need evaluation. Please do an ECG during the time of the palpitations. I would also recommend a 2 D echo to see the functioning a structure of the heart walls and valves and hence evaluate for a cardiac cause of your symptoms. Another cause of your symptoms can be thyroid abnormalities. Please get a thyroid function tests done. Please get It D and It B12 levels also checked with the above. Kindly revert with the above tests.  Wishing you good healthRegards
