title: A pill electrode for the study of cardiac arrhythmia.
abstract: A swallowable electrode has been developed which permits accurate P wave detection without patient risk or discomfort. This esophageal lead, together with a simultaneous surface ECG, is the basis for a new two-channel computer system for arrhythmia detection and analysis.
