Is there a "heart" position that is abnormal? I have pectus.

Pectus ; Heart. Patients with pectus excavatum will have displacement of the heart into the left chest. The degree of displacement and the potential cardiac problems will depend on the severity of the pectus. It can range from a completely normal heart to significant compression causing mitral ; tricuspid regurgitation as well as cardiac arrhythmias. Evaluation by a physician with expertise in pectus is important.
Pectus excavatum. Pectus excavatum is a chest abnormality which results in a depression in the chest wall. Sometimes it is so deep that it compresses part of the heart. Usually it causes no problems and is followed by a physician. One note is that it can be associated with arrhythmias such as supra ventricular tachycardias.
