I have been suffering from lightheadedness and feeling faint for 3-4 years now without proper diagnosis. I was proposed on these forums that the cause might be "atrial septal defect with what is called a right to left shunt".
I have undergone ECG, holter ECG, stress test and normal echocardiography. Everything has been "normal" except sinus bradycardia, down to 45 at rest at wake and RBBB.
Do those tests exclude the possibility of atrial septal defect or should I still ask my doctor for further investigations?
There are two types of connections found between your atria, called an atrial septal defect or a patent foramen ovale. A transthoracic echocardiogram with a bubble study is a very good test to determine the presence of one of these abnormalities. Sometimes, the bubble test needs to be administered from both the arm and the leg. If there is still a question a transesophageal echocardiogram is the definitive test.
