Cardiac Arrhythmias Flashcards
Acute therapy for bradycardia
Atropine, isuprel, temp. Pacemaker, discontinuation of an offending drugs
Chronic therapy for bradycardia
Permanent pacemaker
Sinus bradycardia is when the heart rate
Of less than 60 bpm
An asymptomatic healthy 26 year old athlete that shows to have bradycardia requires therapy?
Nope
Asymptomatic 65 yo with hypertension with an AV block fo the first degree is when PR _____ and is therapy needed?
PR more or equal than .20 sec
- therapy is not indicated
Mobitz type I second degree AV block (AV wenckebach) is a
Therapy?
Progressive prolongation of the PR interval until a P wave is not conducted
- therapy is not generally needed
Mobitz type II second degree AV block is a
Therapy?
Non- conducted p wave with constant PR interval
- therapy requires a permanent pacemaker
in afib how is the atrial activity represented in ekG
by fibrillatory waves
rapid irregular, and even chaotic form of atrial tachyarrhythmias with an irregular ventricular response
- lack of p waves and irregularity of r waves
aFib
goal for afib treatments
- prevent stroke
- slow ventricular response
- restore and maintain NSR- cardioversion with a synchronized shock
sawtooth pattern that indicated a retrograde conduction up the atrial septum
Aflutter
acute therapy for SVT (2)
chronic threapy for svT (2)
Acute: (1) cardioversion (2) IV adenosine
Chronic: (1) ablation (2) antiarrhythmics BB or CCB
SVT acute treatment pathway for:
- stable
- unstable
- stable- vagal maneuvers –> adenosine IV –> verapamil IV –> synchronized cardioversion
- unstable: adenosine –> synchronized cardioversion
slurred QRS upstroke and delta wave
WPW
delta wave disappears with ablation in WPW
