Brief Answer:

Need some details.

Detailed Answer:


After going through the medical details provided by you I understand your concern.

I would like to tell you that all this was most likely the result of a viral illness which has transiently affected her heart but as the viral illness recovered things got improved.

As she is fine now there is no need to worry for now. If you have the ECG and Echo report kindly upload them for review.

However a repeat ECG and Echocardiography should be carried out after 3 months to make sure there is no residual effect left behind from the illness.

I hope this information will relieve your worries.

Kind Regards
