StaRN EKG STUDY GUIDE 25 MOST REPEATED QUESTIONS AND CORRECT ANSWERS 2023 LATEST UPDATE.

Rhythm: Regular Pwave: before/after/absent - inverted PR: unknown QRS: Normal *** Fast junctional escape 2. Asystole: absence of contractions of the heart-Flat Line 3. Atrial fibrillation: rapid, random, ineffective contractions of the atrium 4. Atrial Flutter: 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 5. Atrial Pacing: spike before P wave 6. Idioventricular Rhythm: Rate: 20-40bpm Regularity: regular P-wave: absent QRS-complex: wide and bizarre PR-interval: absent 7. Junctional Escape: Rate: 40-60 bpm, P wave: inverted, absent, or after the QRS, QRS: normal 8. Juctional Tachycardia: 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 9. Pulseless Electrical Activity (PEA): 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 10. second degree heart block type 1: Progressive lengthening of the PR interval until a QRS complex fails to appear after a P wave 11. Second Degree Heart Block (Mobitz II): Normal, Normal, and drop a QRS. Noncuducted P wave, with constant PR intervals and QRS.
