Detecting arrhythmias

This chapter introduces you to how ICDs are able to see what the heart is doing! You will learn how ICDs detect arrhythmias and how to interpret device electrograms.
  • Sensing and electrograms
  • Markers and annotations
  • Heart rate criteria—zones
  • Counters part I—consecutive counters
  • Counters part II—rolling window counters
  • Sensing ventricular fibrillation (VF)
  • Detecting arrhythmias quiz

Chapter 3

Discriminating between different arrhythmias

We will teach you how you can use discriminators—the brains behind heart rhythm interpretation—to give your patient as normal a life as possible and avoid inappropriate therapy
  • Discriminators
  • Onset—how did it start?
  • Stability—regular versus irregular
  • QRS morphology—a 'normal' template
  • AV association
  • PR pattern analysis
  • Discriminating between different arrhythmias quiz

Treating arrhythmias

Recognizing an abnormal rhythm is step one—treating it is next! Learn how ICDs terminate dangerous arrhythmias and how you can tailor ICD settings to provide bespoke treatment.
  • What is ATP (anti-tachycardia pacing)?
  • How ATP terminates ventricular tachycardia
  • Types of ATP
  • Defibrillation

Understanding device limitations and solutions

If only these devices were perfect! In this chapter we will teach you the limitations of ICDs and give you the tools to troubleshoot the most common ICD issues.
  • Failure to sense
  • Failure to defibrillate
  • Ventricular fibrillation induction (device testing)
  • Inappropriate therapy
  • Troubleshooting inappropriate therapy for atrial fibrillation
  • Troubleshooting inappropriate therapy for supraventricular tachycardias (SVTs)
  • Troubleshooting inappropriate therapy for T wave oversensing
  • Troubleshooting inappropriate therapy for lead fractures and electromagnetic interference
