NEMSA Cardiology Mod 2

Squiggly Lines

100

This rhythm is characterized by a "sawtooth" pattern and is usually caused by a re-entry circuit in the atria.

Atrial Flutter

200

This rhythm is characterized by a regular rhythm, a 1P:1QRS rate, and a PR Interval of greater than 0.2 milliseconds

First Degree Heart Block

300

A prolonged QT Interval puts a patient at high risk for this specific type of polymorphic Ventricular Tachycardia

Torsades de Pointes

400

This EKG rhythm shows a regular rate with a QRS Interval less than 0.12ms but has inverted P waves or no P waves.

Junctional Rhythm

500

This EKG rhythm shows a regular rate with a usually normal PR Interval, but some QRSs are missing.

2nd Degree Type II (AKA Mobitz) Block

ECG Rules

100

The standard duration of a normal QRS complex should be less than this many seconds?

0.12 seconds

200

What condition causes tall, peaked T waves

Hyperkalemia

300

Supraventricular Tachycardia is identified as a heart rate over what number without external cause?

150

400

Name the rhythm that has wide QRS complexes, fast rate, often regular, no visible P waves

Ventricular Tachycardia

500

This law states that the sum of the voltages in Lead I and Lead III equals the voltage in Lead II

Einthoven’s Law

Follow the Plumbing

100

This coronary artery most commonly supplies the Inferior wall of the heart

What is the Right Coronary Artery (RCA)

200

An occlusion of the Left Main Coronary Artery is often colloquially referred to by this grim nickname

the Widowmaker

300

These are the three specific layers of an artery, from innermost to outermost.

the Tunica Intima, Tunica Media, and Tunica Adventitia

500

These are the two primary arteries that branch off the Left Main Coronary Artery.

What are the Left Anterior Descending (LAD) and the Circumflex (LCx)

Emergency Interventions

100

Per AHA, the energy setting for the first shock when defibrillating is:

360 Joules

200

This procedure is indicated for an unstable patient with a narrow-complex tachycardia

Synchronized Cardioversion

300

When performing Transcutaneous Pacing (TCP), the paramedic must look for both electrical capture and this

Mechanical Capture (a palpable radial pulse)

400

Name 4 of the 5 indicators when determining a patient is stable vs unstable

Systolic <90

S/S of shock

Ischemic chest pain

S/S of heart failure

Altered mental status

500

This specific maneuver involves having the patient blow into a 10cc syringe to attempt to terminate SVT.
