Thanks for your question on Health Care Magic.
I can understand your concern.
No, I don't think this is right diagnosis.
In my opinion, we should first rule out
arrhythmia (rhythm disturbances in heart) in your case. Arrhythmias like atrial
fibrillation,
atrial flutter, supra
ventricular tachycardia etc can cause palpitations, dizziness, headache etc.
So
consult cardiologist and get done blood pressure monitoring, ecg, 2d echo and Holter monitoring (24 hour continuous monitoring of ecg).
You may need anti arrhythmia drug on the basis of these reports.
Don't worry, you will be alright.
But first rule out arrhythmia.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
