Inappropriate Sinus Tachycardia

So, i am 17 old Boy from Lucknow, India. Since birth i had racing pulse rate and gradually over years it increased. I was told that at birth i was born prematurely and had a blue body. Over the years i couldn't understood my problem. When i was in 9th i started facing palpitations, i got to a physician and told me i had anxiety and continued with beta blockers and stertalline hydrochloride and i was again back in condition Whenever beta blockers were withdrawn. For 3 years i was in wrong narrative that i had anxiety and i got homeopathic medicine which supressed my condition and during echocardiogram and electrocardiogram i was diagnosed with nothing. I stopped all treatment having fed up of condition. I didn't have any anxiety, i am very good in studies and fair in everything though obese. Presently i had an increase in condition and palpitations which became violent with slightest exertion. I got to another cardiologist and got echo and ecg. He diagnosed with inappropriate Sinus Tachycardia and in echo was DCMP, grade 1 impaired relaxation. Dcmp was related with tachycardia induced cardiomyopathy since my tachycardia was chronic, permanent and never below 120, it gave rise to it. Presently i am on bisoprolol 5mg daily, have normal pulse rate and normal life, no troubles. I was misdiagnosed with anxiety and i had nothing but inappropriate Sinus Tachycardia which has been rare and asymptomatic but as far as i was concerned, i produced great symptoms and day to day problems like dypsnea and palpitations. Now i am all good and doing well in class 12😊

    Thank you very much for sharing your story. 

    I also have IST. You're right that some doctors don't take it seriously because it is unlikely to kill you immediately, but as you pointed out, it can lead to heart damage over the long term. Also, in my case, I was fainting frequently, and that can certainly kill you if you lose conciousness while driving or something. In any case, it can be very debilitating in your daily life.

    IST is still often misdiagnosed as an anxiety disorder or panic disorder. It still is a misunderstood condition. When I first approached my doctor about my symptoms, I was told that I was just getting old and losing my phyical fitness (I was 33 then). My cardiologist achieved the correct diagnosis after my heart's pacemaker "shorted out" and I went into VFib and brief cardiac arrest, the medical team put me on a heart monitor for 3 days in the hospital, and were able to observe an episode for themselves.

     I am glad that at least you eventually got the correct diagnosis and treatment. What a world of difference that makes!
