Hello,
Thank you for your query at DoctorSpring.com
I have gone through your case history and the EKG and it doesn't seem to be related and also your stress test were all normal.
To give a brief information about the characteristic features of angina

• Chest pain or discomfort
• Pain in your arms, neck, jaw, shoulder or back accompanying chest pain
• Nausea
• Fatigue
• Shortness of breath
• Sweating
• Dizziness

The chest pain and discomfort common with angina may be described as pressure, squeezing, fullness or pain in the center of your chest. Some people with angina symptoms describe angina as feeling like a vise is squeezing their chest or feeling like a heavy weight has been placed on their chest. For others, it may feel like indigestion.
The severity, duration and type of angina can vary. It's important to recognize if you have new or changing chest discomfort. New or different symptoms may signal a more dangerous form of angina (unstable angina) or a heart attack.
ECG is normal and in case A Fib it should be seen in all leads rather then one lead.
Occasional chest pain may be muscular or due to Acid Peptic Disease which can be aggravated by Anti -Platelets which are given as a prophylaxis in A Fib to prevent Embolic episodes .

Dear Doctor, By looking at your EKG there is no evidence of Atrial flutter. It's in Sinus Rhythm that is a normal EKG. Sometimes you have palpitations and you doubt about it , you can do Holter Monitoring so that chances of finding abnormal rhythm is more. Regards Dr Satish

Any patients who have A Fib are at risk of embolism which may be transient because most of the time you may not be feeling the palpitations especially when a patient is on beta blockers when the rate may be controlled, so it's beneficial to be on anti platelets when you don't have any other risk factors , but when patients are having multiple risk factors the patient should be on anti coagulants.
