<human>: i have had low blood pressuse 90/70 and lower since i had my son 6.5 years ago my pulse has been high since 2001 at least thats when it was noticed while i was in hospital. cardiologist said i have a smaller than usual heart which makes my pulse higher . said it may affect me more as i get older as it puts pressure on the arteries. however i have been tired latley . always been dizzy upon standing was told to sit down when my pulse gets high if that was the case i would have spent alot of my days sitting . playing oout side with my son i had to sit down i got dizzy and nauseated eyes couldnt adjust . it happened at christmas time while i was shopping i fell into a shelf lost vision got weak n had to sit down. blood work is great no anemia levels r all good perfect health. so why is this happening . i dont want to have a heart attack
<bot>: Hello Sir / Madam, Thanks for writing in to Chat Doctor. Firstly, since you have been having a history of hypotension, it is advisable to consult a cardiologist for cardiac evaluation :1. ECG- to monitor the electrical events of the heart.2. Echocardiography- to monitor the mechanical events of the heart this will guide us to rule out any cardiac causes of weakness, tiredness etc. Since your blood reports are normal, If the cardiac causes are ruled out then your hormone levels may need to be checked especially the thyroid profile to rule out hormonal causes of tiredness.
