Hi, Recently, my father started to feel difficulty in breathing along with tiredness and fatigue. We took him for corona test thrice and it came out as negative. Later, we took him for some tests related to lungs and we came to know that he has fluid in his lungs, but his lungs are fine and the cause of problem wasn't lungs. We did ECG tests and the report says high level of NP BNP hormones greater than 2000 pg/mL in heart. And he needs to be treated for the same. Could you please look into the reports and let me know what is the best that needs to be done further. I've attached the reports as well.
