Cardiac arrhythmias are a major cause of death (7 million cases annually worldwide 400 000 in
the U.S. alone) and disability. Yet a noninvasive imaging modality to identify patients at
risk provide accurate diagnosis and guide therapy is not yet available in clinical practice.
Nevertheless there are various applications of electrophysiologic imaging in humans from ECG
CT reconstructions MRI to tissue Doppler investigations that provide supplimentary diagnostic
data to the cardiologist. EP laboratories are experiencing an increase in volume for both
diagnostic and interventional electrophysiology studies including mapping ablation and
pacemaker implants. The equipment requirements for these procedures are stringent include
positioning capabilities and dose management. This book is designed to review all of the
current imaging methodologies that assist in diagnosis within the electrophysiology department.
