The EP Lab

Welcome to the EP Lab...

This web site offers a unique perspective for the Allied Health Professional working in the field of Cardiac Electrophysiology. The information found throughout the lab offers a blend of EP facts balanced with the experiences of someone who has worked in the field for 15 years. As the author of The EP Lab, I have sought to provide an online resource that will help Allied Health Professionals gain a better understanding of this exciting, dynamic field.

Many people have asked about the subscription fees associated with this site. I consider this to be an online book that offers similar materials to that which you would find in a printed text. Authors rarely give away books and are compensated for their knowledge and the effort they have put into providing that knowledge to the reader. This site is no different. The subscription costs vary depending upon the number of months you subscribe for. For one month, the cost is $20. If you subscribe for a full year, the cost is $8.33 per month. Below is an outline of what you can expect to find should you subscribe.

Anatomy & Physiology

The cardiac structure is the environment in which we work. The more you know about the heart, the more effective your skills in the lab will become. This section covers the essential cardiac structures and the role they play in both normal and abnormal cardiac activity. The following sections are found in this section of the site;

  • The Cardiac Structure
  • The Right Atrium
  • The Right Ventricle
  • The Left Atrium
  • The Left Ventricle
  • The Conduction System
  • Action Potentials
  • Cellular Properties
  • The Autonomic Nervous System - Sympathetic and Parasympathetic Responses
  • The Med Page - An overview of the different medication classifications

Electrograms

Electrograms are the language of EP. To become proficient in the lab, you can learn how to push all the buttons on the equipment. To master EP, you must learn to read electrograms. This section contains information that describes everything you need to know to learn the language of the lab.

  • Electrograms Defined
  • Recording Modes - What the real difference between unipolar and bipolar is.
  • Electrode Spacing - How bipolar can start to look unipolar.
  • Filters - The least understood difference between unipolar and bipolar.
  • Electrogram Interpretation - The fundamentals of reading EGM's.
  • Surface ECG's - Review of the basics of Surface Electrocardiograms.
  • Intracardiac EGM's - Review of the basics of Intracardiac Electrograms

Procedures

This section is dedicated to the different procedures performed in the EP Lab.

  • Setting Up
  • Catheter Placement
  • Baseline Measurements
  • Sinus Node Recovery Time
  • Conduction Studies
  • Arrhythmia Induction
  • Pacing Maneuvers
  • Cardiac Mapping
  • Ablation
  • Tilt Table Studies
  • Secrets to Success

Arrhythmias

The whole purpose of working in the lab is to determine if an abnormal rhythm is present. This may be an arrhythmia or a dysrhythmia. This section is dedicated to learning how to identify the various rhythms that are encountered in the lab. There is discussion of the mechanisms behind the rhythms and the cardiac structures that are most commonly involved with the various rhythms.

  • Bradycardia
  • Atrial Tachycardia
  • Atrial Flutter
    • Typical
    • Atypical
  • Atrial Fibrillation
  • AVNRT
  • AVRT (WPW)
  • Ventricular Tachycardia
    • Arrhythmogenic Right Ventricular Dysplasia
    • Outflow Track Tachycardias
    • Bundle Branch Reentry
    • Ishcemic VT

The Resource Center

As I find information that may be helpful for Allied Health Professionals, I will post it in this section. This area provides information on the following subjects;

  • EP Education Resources
  • EP Organizations
  • Industry Sites
  • Tomes & Texts
  • EP Articles
  • Practice Rhythm Strips
  • Practice Intracardiac Recordings
  • Anatomy Questions
