DRAW DIAGRAM , MARINE TWO STROKE MAIN ENGINE
THIS ARE TAKEN FROM PROFILE OF ONE OF THE CAPTAIN.........
2 years ago, he went to the company doctor for my pre-medicals.
after taking my ECG the young female doctor, called her young male colleague and both of them perused my ECG graph for about 5 minutes-- all the time muttering under their breaths to each other. he was all the while lying down patiently with all the paraphernalia stuck to my chest.
then the male doctor asks him " captain, do you have a heart problem?"
furious , he hissed back " from 4 metres away while lying down, from this acute angle , from upside down , he have seen there is nothing on that dang graph , to make you ask me this naive question. he suggest him immediately ask your more well informed colleagues"
after 10 minutes they come running back , huffin' and puffin' --" there is nothing wrong with your heart, sorry for the inconvenience!"
then the female doctor asks him " captain, how to you learn to read the ECG graph ?"
hereplied " at sea we read more complicated graphs !"
( to be frank, when his father had his first heart attack , he bought lot of medical books and expensive CDs' and learnt a lot. at that particular time he could deduce a korotkoff sound and ECG as well as any experienced cardiologist )
