Study Description
Brief Summary:
The purpose of this study is to gather information about the size and shape of patients' hearts in order to design a device.

Condition or disease Intervention/treatment
Atrial Fibrillation Other: There is no intervention that is a part of this study.

Detailed Description:
Correct device design depends on getting good information about the shape and size of the different parts of the heart. Measurements from computed tomography images of hearts will be studied. By looking at measurements from a wide range of patients, an understanding of the differences in the size and shape of the heart chambers will be gained.
