My daughter is 20 and her heart was racing very fast sunday while just sitting there, we went to her primary and they did an ekg and said the left side of her heart is enlarged and she needs to see. Cardiologist, should I be freaking out because I m very worried
Thanks for your question on Chat Doctor. I can understand your concern. Yes, you should definitely consult cardiologist for your daughter. Her symptoms like sudden racing of heart and enlarged heart on ECG can be due to Dilated cardiomyopathy (DCM) or valvular heart disease. So better to consult gynecologist and get done 1. Fresh ECG 2. 2d echo 3. Holder monitoring (24 hours continuous recording of ECG). She may need surgical correction and other cardiac supportive Chat Doctor.  Don't worry, she will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter. Thanks.
