Brief Answer:
A few clarifications required sir/ma'am
Detailed Answer:
Hello sir/ma'am and welcome.
Thank you for writing to us.
I am sorry to hear about your father's poor cardiac health. But, there is something unclear with the information provided. 20 % is usually measured as the cardiac output, whereas
heart rate is measure in beats per minute (normal range 60 -100).
A heart rate of 20 BPM could be caused by various conditions and a life expectancy cannot be predicted based on that, whereas, a cardiac output of 20 % can help in calculating a life expectancy which would be anywhere between 2-5 months (5 months being extremely optimistic).
But based on your history, you mention heart rate repeatedly, and that his heart rate was 25 %, so I am guessing you are not speaking about
ejection fraction. Please clarify whether this is heart rate or not sir/ma'am, and I shall reply with a more elaborate explanation. Please also attach all documents from the doctor and all reports for my reference, because I cannot comment on the diet without the diagnosis sir/ma'am.
Once I know which parameter this is and what the diagnosis is, I will be able to explain the precautions and diet accordingly. I await your kind response in order to help you further. I would also like to add, if an investigation called 2D
echocardiography has not yet being conducted, please conduct the same and write back to me with the detailed report or you could attach the reports to our discussion and I shall go through this with diligence.
I hope you find my response helpful. I am looking forward to hearing from you in order to help you further.
Best wishes.
