47 clinical arrhymia Flashcards
What are the 4 non-pharmacological therapy for arrhythmia?
pacemaker
electrical defibrillation/cardiovresion
implantable cardioverter-defibrillator
catheter based or surgical ablation
What are the 2 most common cardia arrhythmias?
atrial fibrillation and atrial flutter
What are 2 general strategies for cardiac arrhythmia?
rhythm control and rate control
How do we elicit rate control?
slow ventricular rate by blocking AV node conduction; beta blocker, Ca blocker, digoxin, adenosine for diagnosis
How do we elect rhythm control?
electrical or chemical cardioversion/revent reoccurrence: amiodarone if heart disease
What is an extremely effective treatment for flutter?
ablation
In supraventricular tachycardia SVT: AV nodal reentry, how for we treat? 3
Acute= break reentry- Ca blocker adenosine
Prevent reoccurrence- Ca or beta blockers
Ablate slow pathway of AV node leaving fast path
What are the 5 treatment considerations for ventricular tachycardia?
break acute- lidocaine, amiodarone, electrical cardioversion
prevent occurrence- beta blocker
prevent reoccurrence- beta blockers, amiodarone, sotalol
Ablation-
impantable cardioverter- defibrillator
What are the 4 treatment considerations for V fib treatment?
break acute- electrical defib, amiodarone
prevent occurrence- beta-blockers
prevent reoccurrence- amiodarone, stall
Implantable cardioverter- defibrillator
What is caused by conditions that prolong QT interval?
Torsades de Pointes
What are the 4 considerations for treatment of torsades de points?
- break acute- defib, lidocaine
- prevent occurrence- stop agents causing long QT
- Prevent reoccurrence- mag sulfate, isoproterenol, or pacemaker
- implantable cardioverter-defibrillator
What should we use for heart failure?
ACEI/ARB, beta blocker, nitrate/hydralazine
What should we use for angina
beta blocker, nitrates, Ca channel blocker
What should we use for A fib/ flutter?
beta blocker, diltiazem, verapamil
What should we use for bradycardia or conduction disease?
avoid beta blocker, diltiazem verapamil
