Pdf Summary

In this document, Dr. Frank Zimmerman discusses the causes, classification, and management of bradycardia along with the fundamentals of pacemakers and ICDs. Chapter 1 focuses on sinus bradycardia, including common causes such as sinus node dysfunction, medications, and metabolic/endocrine disturbances. Treatment options for bradycardia include removing medication causing it, correcting metabolic disturbances, avoiding triggers, and using medical intervention or temporary/permanent pacing if necessary. Chapter 2 discusses AV block, its classification, and its incidence after acute myocardial infarction. It also covers the indications for temporary pacing and the management of AV block after myocardial infarction. Chapter 3 provides an overview of pacemakers and ICDs, including the various pacing modes and troubleshooting techniques. It explains the importance of AV synchrony in pacing and the use of magnets to stop pacemaker-mediated tachycardia or inhibit inappropriate shocks from ICDs. The document concludes by highlighting the hemodynamic benefits of dual-chamber pacing, common causes of pacemaker malfunction, and the use of magnets to inhibit sensing or shock therapies.
