Nothing is more perplexing to the clinician new to device therapy than having to deal with cardiac electrocardiograms from a device patient. Suitable for clinicians new to device therapy, this work offers practical information on paced cardiac electrograms.

Nothing is more perplexing to the clinician new to device therapy than having to deal with cardiac electrocardiograms from a device patient. Pacemakers and other implantable cardiac rhythm management devices leave their 'imprint' on ECGs and can significantly change what clinicians see - or expect to see. Evaluating paced ECGs can be challenging, yet nowhere is it taught in any sort of comprehensive manner. Designed specifically for clinicians new to device therapy, "The Nuts and Bolts of Interpreting Paced ECGs and EGMs" offers practical, reliable and objective information on paced cardiac electrograms. Written in a lively, intelligent and easy to navigate style, emphasizing real-life clinical practice and practical tips, this book includes illustrated paced ECGs by skilled artists to help minimize 'fuzzy' lines and emphasize key points. Each chapter concludes with a checklist of key points from each subject ('Nuts and Bolts').
