My friend got afib from covid .she tried many shock treatments. ddn't work. they did an ablation monday & tuesday they rushed her to emergency as she couldn't breathe. she had fluid on the lung. is this normal after a heart ablation? tx?

Base on your age, your friend is probably an octogenarian as well. Fluid in the lungs is the lay term for congestive heart failure and with your friend it is most likely due to poor cardiac output from arrhythmia. Ablation sometimes has serious complications which include heart block, acute pericardial effusion with or without cardiac tamponade, etc.

In this type of situation I would opt for rate control with digoxin rather than trying further ablations. Eventually elective electric cardioversion can be carried out when her congestive heart failure is stabilized. However our more modern cardiologists seem to fear digoxin although I & my colleagues used it many years cautiously with great success in controlling the ventricular response in A Fib
