Terms in this set (25)
Find and tx cause
If symptomatic: atropine, pacing, dopamine
Normal variant, no tx
Tx like bradycardia only if symptomatic
PAC or Blocked PAC
No tx necessary. If increasing in frequency may warn of more serious atrial dysrhythmias to come.
Wandering Atrial Pacemaker
Normal variant in children, usually no tx indicated
Multifocal Atrial Tachycardia
Commonly associated with pulmonary disease, rule out dig toxicity
Atrial Tachycardia or A tach with block
Causes may include dig toxicity, CHF, hypoxia, MI. Vagal stimulation, adenosine, cardioversion, drug therapy, beta blockers, calcium channel blockers)
May be caused by CHF, Rheumatic heart disease, ect.
Loss of atrial kick, thrombi common and embolization can occur. Cardioversion may be indicated with a need for anticoagulation. Controlling ventricular response may be necessary.
Serves as a back up rhythm, if symptomatic tx like brady
Caused by enhanced automaticity of the AV node, R/O dig toxicity.
Only use this term when unable to confirm P's are present or absent in the setting of normal QRS and fast HR. Vagal stim, adenosine, cardioversion or drug therapy, beta blockers calcium channel blockers.
Consider cause, hypoxia, ischemia, electrolytes, acidosis, many meds
Idioventricular Rhythm or Ventricular Escape Rhythm
Rate of 15-40, serves as a backup rhythm. If symptomatic tx like brady.
Accelerated Idioventricular Rhythm
Rate of 40--100, serves as back-up rhythm, do not suppress. Not likely to be symptomatic.
140-200. May be pulseless, stable, or unstable which will determine tx. Amiodarone, Lidocaine, Procainamide ect: Cardioversion vs Defibrillation. Anything that causes PVCs can cause this rhythm.
No pulse or breathing, immediate defibrillation necessary. CPR, Epinephrine, Antiarrhythmics like Amio, Lidocaine, Procainamide, Determine cause and correct if able.
No specific tx. Distinguished from v. rhythms based on associated P waves.
1st degree AV block
Conduction problem in the AV node. May be caused by MI, drugs, OH surg. Usually no tx, monitor for more serious blocks.
2nd degree AV type 1 Wenckebach
Conduction problem in the AV node, d/c causative drugs, watch for more serious heart blocks, tx like brady only if symptomatic.
2nd degree AV block Type II
More serious conduction problem because problem is below the AV node. Pacing reccomended. Atropine may increase the number of P's trying to get conducted and can make the block worse
3rd degree AV block
Causes include MI, chronic conduction disease, congenital heart disease, OH surg, dig tox, Pacing recommended. If pt is symptomatic, tx like bradycardia. Be sure to note where the QRS orginate from
Confirm in 2 leads to assure not vfib, CPR, ETT, Epi, antiarrythmics
Eval QT prior to tachy starting. Mag sulfate. Avoid meds that prolong QT interval. Defib if pulseless.
