My ecg reports right bundle branch block,left posterior fascicular block and bifascicular block. may i use oats,protein food, milk and dairy products?

Sure: Your EKG findings shouldn't affect your diet. As with anyone (regardless of what your EKG shows) it's important to eat a balanced diet with plenty of vegetables and whole grains. A moderate amount of low fat dairy products are fine too.

Nutrition: Yes you may. Be sure your diet is low saturated fat, high antioxidants, and high polyunsaturated fat. Keep salt low. Keep sugar low
