Thanks for posting your query on HealthcareMagic.

Palpitations occur in conditions like anxiety or heart disorders.
Thus, you need to consult your primary healthcare provider for clinical assessment and cardiac investigations like ECG and echocardiography if required.
Blurring of vision can occur due to refractive errors or infections commonly.
However, you can consult your ophthalmologist for clinical assessment and relevant investigations to look for cause of blurring vision.
