Abstract:
Even for a basic study, the electrophysiologist needs to have a clear mental picture of cardiac anatomy when positioning the diagnostic catheters. This review highlights some of the features of the four cardiac chambers relevant for translating anatomic knowledge into an understanding of fluoroscopy images and electrograms. Integration of images from real cardiac anatomy into three-dimensional mapping based on electrograms and "virtual" anatomy is crucial for the success and safety of diagnostic and therapeutic electrophysiological procedures.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
