Rhythm Identification

You can stare at rhythm strips all day, but you’ll never be consistent at correctly identifying the rhythm until you master the criteria of each rhythm. Before you start looking at strips take the time to learn what makes each rhythm unique.

It does take some practice but once you have the hang of it you’ll really increase you accuracy and speed in identifying various rhythms.

For those with experience: This isn’t a learn it once and forget it skill. This is something you should brush up on every once in a while.

Things To Remember – Part 1

Although this is an EKG study guide it is not intended to be a complete stand alone work of reference. It is merely a study guide I used while attending a paramedic course of study at Vincennes University. I have many more study guides (study aids) to publish when I get some extra time. The information presented is in no particular order and should not be considered medical advice. It’s accuracy is not guaranteed as I’m tired and typing this late at night. Enjoy!

P Wave = Atrial Depolarization, Atria Contract
PR Segment = Delay at AV Node, Atria Relax, Atrial Repolarization
PR Interval = Total Atrial Activity
QRS Complex = Ventricular Depolarization, Ventricles Contract
ST Segment = Ventricles Begin To Relax, Ventricular Repolarization Begins
T Wave = Ventricular Repolarization and Relaxation Completed
ST Interval = Total Ventricular Relaxation
QT Interval = Total Ventricular Activity

Measuring PRI:

  • The PRI is measured from the beginning of the P wave to the beginning of the QRS
  • The normal PRI is 0.12 – 0.20 seconds (3-5 small blocks)

Measuring QRS:

  • The QRS is measured from the beginning of the Q wave to the end of the S wave
  • The QRS is normally less than 0.12 seconds

Autonomic Nervous System:

  • Sympathetic Branch

Affects the atria and the ventricles

Increases heart rate, conduction, irritability

  • Parasympathetic Branch

Affects only the atria

Decreases heart rate, conduction, irritability

Electrical Conduction Through the Heart:

  1. SA Node
  2. Intra-atrial pathway
  3. Inter-nodal pathways
  4. AV Node
  5. Bundle of HIS
  6. Left Bundle Branch
  7. Right Bundle Branch
  8. Purkinje Fibers

Inherent Rates:

SA Node – 60-100 bpm
AV Node – 40-60 bpm
Ventricular – 20-40 bpm

Simulation Training: Cadaver Lab

I recently participated in a training/education session at a prominent hospital in Indianapolis. I participated in an eight hour session involving a 91 year old female cadaver. I was surprised, pleasantly, by the inclusion of other health care providers in the session. EMS professionals, a few nurses, and a couple of doctors participated and shared information among each other during the session. The staff leading the session were all paramedics with special training in the instruction and use of cadavers. I was informed that only seven or so people in Indiana have received this training.

One of the paramedics leading the session is also a funeral director.

Laryngoscopes

Laryngoscopes

The purpose of the session was to practice skills generally considered susceptible to skill decay with a primary focus on surgical and needle cricothyrotomy using traditional laryngoscopy and video laryngoscopy via a GlideScope. The bulk of the training session focused on the anatomy & physiology associated with the procedures. Alternate methods of determining landmarks were demonstrated and everyone in the session was evaluated and performed multiple identifications on our cadaver. Discussions included scenarios where improper landmark identification could become problematic.

We spent more than 75% of the allotted time on airway management. This included basic airway management using BVM, oral and nasal adjuncts, King Airway & CombiTubes, LMA insertion, and S.A.L.T device.

Tracheal intubations were practiced by all using both Macintosh and Miller blades as well as the video GlideScope. Everybody had the opportunity to perform as many intubations as they liked. Staff was very approachable and eager to offer tips and solutions to common problems associated with tracheal intubations in the field. Gum Bougie use was also demonstrated and utilized in our practice session as well as intubation without the device.

Supraglottic Airway Laryngopharyngeal Tube

I was unaware of the S.A.L.T device as it isn’t used in my system. I found it particularly interesting since it may make tracheal intubations fast and easy. The general consensus was that if this device was all it is advertised to be it might very well be the best BLS oral adjunct option available. I wonder why it isn’t more prominent.

At the very least it should be an option in my opinion.
