Thanks for your question on Healthcare Magic.
I can understand your concern.
Since you are having VSD (
ventricular septal defect) and
asthma, possibility of heart related diseases or worsening of asthma is more for your current symptoms.
So
consult doctor and get done
1. Blood pressure monitoring, ecg, 2d echo and
stress test (trade mill test) to rule out heart diseases.
2. Chest
x ray and PFT (pulmonary function test) to rule out worsening of asthma.
On the basis of above reports, you may need cardiac supportive drugs and inhaled treatment.
So, don't wait at home, consult doctor, first diagnose yourself and then start appropriate treatment.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
