1
Q

Acute therapy for bradycardia

A

Atropine, isuprel, temp. Pacemaker, discontinuation of an offending drugs

2
Q

Chronic therapy for bradycardia

A

Permanent pacemaker

3
Q

Sinus bradycardia is when the heart rate

A

Of less than 60 bpm

4
Q

An asymptomatic healthy 26 year old athlete that shows to have bradycardia requires therapy?

A

Nope

5
Q

Asymptomatic 65 yo with hypertension with an AV block fo the first degree is when PR _____ and is therapy needed?

A

PR more or equal than .20 sec

  • therapy is not indicated
6
Q

Mobitz type I second degree AV block (AV wenckebach) is a

Therapy?

A

Progressive prolongation of the PR interval until a P wave is not conducted

  • therapy is not generally needed
7
Q

Mobitz type II second degree AV block is a

Therapy?

A

Non- conducted p wave with constant PR interval

  • therapy requires a permanent pacemaker
8
Q

in afib how is the atrial activity represented in ekG

A

by fibrillatory waves

9
Q

rapid irregular, and even chaotic form of atrial tachyarrhythmias with an irregular ventricular response

  • lack of p waves and irregularity of r waves
A

aFib

10
Q

goal for afib treatments

A
  1. prevent stroke
  2. slow ventricular response
  3. restore and maintain NSR- cardioversion with a synchronized shock
11
Q

sawtooth pattern that indicated a retrograde conduction up the atrial septum

A

Aflutter

12
Q

acute therapy for SVT (2)

chronic threapy for svT (2)

A

Acute: (1) cardioversion (2) IV adenosine

Chronic: (1) ablation (2) antiarrhythmics BB or CCB

13
Q

SVT acute treatment pathway for:

  1. stable
  2. unstable
A
  1. stable- vagal maneuvers –> adenosine IV –> verapamil IV –> synchronized cardioversion
  2. unstable: adenosine –> synchronized cardioversion
14
Q

slurred QRS upstroke and delta wave

A

WPW

15
Q

delta wave disappears with ablation in WPW

A

yep

16
Q

sustained monomorphic VT:

  1. stable
  2. unstable
A
  1. stable: lidocaine UV –> amiodarone IV

2. unstable: synchronized cardioversion

17
Q

Vfib:

  1. acute
  2. chronic
A
  1. acute: defibrillation

2. chronic: ICD
