Peak RV/RA Systolic Pressure Norms

Hello:
I'm a 48 y/o Caucasian male at 5'6" & 200 lbs, Dx'd w/ Paroxysmal A-Fib back in 12/06. No other medical issues except pre-hypertension (135/85) & high BMI. My PCP & cardiologist initially Rx'd weight loss, stimulant avoidance, Aspirin 325mg & Atenolol 25mg/day. All labs values were normal. 24-Hr. Holter showed NSR except for 1 palpitation x 2-3 minutes. Baseline echo results after meds started: Normal left ventricular function, Mild mitral regurgitation (advised SBE prophylaxis), Peak TR regurgitation velocity of 1.46 m/s & Peak RV systolic pressure 8.5 mmHg greater than RA pressure. This last reading - peak RV systolic pressure 8.5 mmHg > RA pressure - apparently is below the normal range of 20-30 mmHg. Can you tell me what could be the causes/implications of this low reading?  My cardiologist said he would be more concerned if the readings were above the normal range. To date/14 months later, my A-F/palpitation episode freqency has increased. My cardiologist increased my Atenolol dosage to 25mg, 2x/day & felt another echo is not necessary at this time. If the AF frequency/duration increase further, then rhythm control meds could be considered. What are your thoughts on this plan? Thank you very much.

Your doctor is right, high RV pressure would have been more concerning. Also,depending on the frequency and severity of  of A fib episodes a rhythm control medication may be added
