Hello!
Welcome and thank you for asking on HCM!
Regarding your concern, I would explain that a comprehensive differential diagnosis between anxiety and
cardiac arrhythmia should be done.
You should know that even the trauma she has gone through (foot breaking) could be related to anxiety and heart palpitations.
I would recommend consulting with the GP for a careful physical examination , a resting ECG and a chest x ray. Some blood lab tests (
complete blood count, PCR, sedimentation rate,
thyroid hormone levels,
cortisol plasma levels, fasting glucose and blood electrolytes) are needed to exclude other possible metabolic causes like chronic anemia, thyroid or adrenal gland dysfunction.
An ambulatory 24-48 hours monitoring and a cardiac
ultrasound may be necessary if suspicions of a possible cardiac arrhythmia are raised.
If all the above tests result normal, the most probable cause of her symptomatology would be just pure anxiety.
Hope to have been helpful!
Feel free to ask any other questions, whenever you need!
Greetings!
Dr. Iliri
