Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: I do not smoke, and actually had an EKG at the Emergency Room today which came back normal. Could a normal EKG mean heart failure is off the table? Your positive words mean the world to me, friend.. ### Response: Well, heart failure is a clinical diagnosis. An EKG may help but doesnt give you the answer. For example the EKG can tell you there might have been a heart attack or signs of decreased oxygen or clue you in that one side of the heart is enlarged but thats about it.We usually use a combination of symptoms and labs to say someone has heart failure. Again, your PCP will be able to help. Again there are a few diet threads on here were guys your size have dropped a bit of weight..
