Hello
Thank you for your query at DoctorSpring.com
I understand your concern.
The Holter examination is not showing any arrhythmia which correlates with your symptoms. Except for sinus tachycardia there is no significant rhythm abnormality when you complain of symptoms. You should check your hemoglobin and thyroid function test to rule out causes of sinus tachycardia. Anxiety can be another cause. While climbing stairs you have shortness of breath.
This is accompanied with ecg changes. I am not aware of your age, hypertension and diabetes status smoking alcohol and oc pill status. So I am not able to comment on the significance of these exertional st segment depression in your ecg. Kindly provide the same details and I will get back to you,
Regards
Dr Vivek Mahajan
