StaRN EKG Test Guide

Accelerated Junctional - Answer Rate: 60-100 Rhythm: Regular Pwave: before/after/absent - inverted PR: unknown QRS: Normal *** Fast junctional escape Asystole - Answer absence of contractions of the heart-Flat Line Atrial fibrillation - Answer rapid, random, ineffective contractions of the atrium Atrial Flutter - Answer Rate:Atrial 250-350 Ventricular: 100 -175 P: Irregular or absent, often "saw tooth" QRS: Normal Conduction: AV Block (2:1 3:1, 4:1) Rhythm: Regular (usually) - Often underlying cardiac disease Carotid massage: increases block Atrial Pacing - Answer spike before P wave Idioventricular Rhythm - Answer Rate: 20-40bpm Regularity: regular P-wave: absent QRS-complex: wide and bizarre PR-interval: absent Junctional Escape - Answer Rate: 40-60 bpm, P wave: inverted, absent, or after the QRS, QRS: normal Juctional Tachycardia - Answer form of supraventricular tachycardia, a type of racing pulse caused by a problem in the area between the upper and lower chambers of your heart. It's known as the atrioventricular node, or AV node Pulseless Electrical Activity (PEA) - Answer a condition in which the heart's electrical rhythm remains relatively normal, yet the mechanical pumping activity fails to follow the electrical activity, causing cardiac arrest second degree heart block type 1 - Answer Progressive lengthening of the PR interval until a QRS complex fails to appear after a P wave Second Degree Heart Block (Mobitz II) - Answer Normal, Normal, and drop a QRS. Noncuducted P wave, with constant PR intervals and QRS.
