IT IS USED FOR CPR AS A FIRST LINE DRUG FOR VFIB, PULSELESS VTACH, ASYSTOLE, OR P.E.A. IT IS CONTRAINDICATED FOR HTN flushing,bronchospasm,AVblock AV Blocks First degree heart block 1st degree block 1st degree block nursing intervention: Second degree heart block type 1 2nd

CHECK THE PATIENT! No pulse = CPR Adverse signs = ELECTRICITY (Cardioversion) No adverse signs = DRUGS What is the rhythm? Atrial Flutter Treatment? What is the rhythm? Sinus Bradycardia What is the rhythm? First Degree AV Block What is the rhythm? Second Degree AV Block Mobitz Type I

First-degree atrioventricular block First-degree AV block occurs when conduction of electri-cal impulses from the atria to the ventricles is delayed. This delay usually occurs at the level of the AV node, or bundle of His.

Steps to Interpreting an EKG Rate Rhythm Axis Intervals (PR, QRS, =Delayed conduction from atria to ventricles First-degree AV block PR>0.20 seconds NO dropped QRS Second Degree AV Block Wenckebach (Type 1) =block within AV node PR interval progressively lengthensthen dropped QRS

Steps to Interpreting an EKG • Rate • Rhythm • Axis • Intervals (PR, QRS, QTc) • Hypertrophy • ST segments • T waves • Q waves. Rate. This is the main feature of the First degree Av Block. Other than the PR prolongation, the EKG may otherwise appear normal. 2. Type II Second

What would your first step be? Are there some interventions that you would perform concurrently? 3. Answer: D. 3rd degree AV block is the most symptomatic form of heart block, and often requires placement of a pacemaker An EKG would be helpful, but should not delay treatment.

(e.g., tumor) Trauma (e.g., cardiac surgery) Congenital abnormality AV Block AV Block – Definitions First Degree: Prolonged conduction time Intermittent non-conduction Third Degree: Persistent non-conduction EKG/Clinical Clues to site of 2:1 Second Degree AV block QRS narrow

First-Degree AV block = prolonged PR interval (> 0.20 seconds or 5 small boxes on the EKG strip) In First-Degree AV Block, If the first shock fails, CPR will circulate the blood and bring more oxygen to the heart, making

Bundle Branch Blocks (BBB) Atrial Ventricular Heart Blocks Types of AV Blocks First Degree AV Block (1º AVB) PR interval > .20 Mobitz I: PEA=CPR, pace. Asystole=CPR,pace. PAT/PSVT=vagal. iBP=NS/Dopamine. VT w/ pulse=Amio/Lido(w/o=defib) AFib=anticoag and .

First-degree AV Block: Second-degree AV Block – Type I Also called Mobitz I Also called Wenckeback (pronounced Winky-bok) This is a slow rhythm. • It looks like Sinus Bradycardia with a progressively lengthening PR interval “Please start CPR.

D. Perform high-quality CPR until an AED arrives 3. The first rhythm analysis indicates “no shock advised.” What is the most appropriate action to perform degree AV block. ACLS Provider Course Annotated Exam Version B 7
