treat arrhythmias Flashcards
What is used to terminate most episodes of PSVT
IV adenosine or IV or oral verapamil used mostly
… but esmolol, metoprolol, dilitiazem, and digoxin are possibilities
What are the treatments for mechanical interruption of acute Paroxysmal supraventricular arrhythmias?
valsalva maneuver coughing breath holding stretching putting thehead between the kenees applying cold water to the face unilateral carotid sinus massage
Prevention of supraventricular arrhythmias
diltiazem and/or verapamil or a B-blocker
treatment of atrial flutter
Ibutilide
or electral cardioversion
What is the treatment of choice for a chronic a-flutter
amiodarone or dofetilide
-radiofreq ablation recommended for refractory or recurrent conditions
what is defined as three or more consecutive ventricular premature beats
V-tach
What is V-tach a frequent complication of
acute MI and dilated cardiomyopathy
V tach in which the QRS complex twists around the baseline.
Torsades de pointes
In what pt does Torsades de pointes occur
spontaneously or when the patient has hypokalemia or hypomagnesemia, or following administration of drugs that prolongs the QT
Describe Long QT Syndrome
may be congenital or acquired and causes recurrent syncope, a QT interval usually 0.5 to 0.7 seconds long, ventricular arrhythmias, and sudden death
Genetic disorder, more common in Asians and in men, that causes syncope, ventricular fib, and sudden death
Brugada’s syndrome
No effective pumping action exists, without intervention, death ensues
V-Fib
Which ventricular arrhythmia is associated with sudden death, most often in the mornings?
Ventricular Fibrillation
what is the treatment of Ventricular premature beats
beta blockers in symptomatic patient; class I and III agents can be used with caution only in symptomatic patient
In V tach with severe hypotension or loss of consciousness?
synchronized cardioversion may be necessary; ventricular overdrive pacing may help
