I was told to see a specialist for possible Pulmonary Hypertension after getting an abnormal ECG. The cardiologist found no cause for concern with my ECG and ECHO. What can be causing it? I recently quit smoking after 7 yrs (5-7 cigs/week). I've never had any major medical issues, but this pain is causing me to worry. ECHO: Left ventricular systolic function is normal Ejection Fraction is 52% Mild mitral and tricuspid regurgitation Moderate aortic regurgitation Aortic valve is mildly thickened
