Simplified Interpretation of ICD Electrograms

Book excerpt: Written as a companion text to Dr Hesselson's first book aboutpacing, Simplified Interpretation of ICD Electrograms focuses onteaching an understanding of the electrogram (EGM) signal fortroubleshooting ICD rhythms. The book includes an in depth reviewof the general function of an ICD (defilbrillation electronics,arrthythmia detection/therapy), as well as an extended summary ofthe commonly encountered arrthythmia in an EGM and ECG format.Throughout the book, Dr Hesselson emphasizes that the key fortroubleshooting these devices lies in the ability to make thetransition from surfaceECG to EGM interpretation. Also included isan extensive chapter on biventricular pacing, particularly as itrelates to its function in an ICD. The book ends with 50 clinicalcase studies designed to illustrate the text's keyprinciples. No one has attempted previously to explain the EGM signal in such apedagogical style, and no significant amount of material has beenformally published detailing methods for troubleshootingbiventricular ICD pacing systems. * Expert guidance on understanding the EGM signal fortroubleshooting ICD rthythms. * Includes 50 clinical case studies. * Covers all aspects of the general function of ICDs. * Contains an extensive chapter on biventricular pacing.
