2-3 times a week I will get a heart rate between 120-140 light headed blurry vision, ear fuzzy sound & weak feeling have to sit & goes away. Reason?

Cardiac Consult. Need to see your cardiologist and likely to electrophysiologist . Urgent.
Arrythmia. Sounds like an irregular rate or rhytm of your heart like supraventricular tachycardia which can be due to atrial fib. You need a baseline ECG to rule out wolf parkinson white syndrome and a holter monitor. Your pcp will navigate your referral to specialist like an electrophysiologist if needed and check your thyroid hormone and electrolytes.
