Hello and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
It's possible that hyperthyroidism (drug induced) could be causing your symptoms. Fast heart beats are common than irregular heart beats. If you have irregular heart beats and light headedness, please meet a doctor to check your blood pressure, ECG and based on that, you may also need additional tests like holter monitoring and echo.
