|
evaluating dysrhythmias |
Treat the patient! how is the rhythm being tolerated indentify cause treat cause |
|
|
most common causes for dysrhythmias that lead to hospitalization |
MI, electrolyte imbalance, degeneration of conduction system |
|
|
s&sx of decreased CO |
hypotension- chk BP! dizzy, lightheaded, nausea, confusion, LOC, etc |
|
|
electrophysiology study (EP study) |
can stimulate the dysrhythmia and check heart while it's happening |
|
|
ECG |
12 lead, 12 different views of heart- moment in time |
|
|
EP study complications |
*perforation and bleeding into pericardium-> pericardial effusion tamponade, v-fib
cardiac specialist does this procedure |
|
|
what do antidysrhythmics do |
suppress dysrhythmia formation |
|
|
antidysrhythmic class I |
I-a, b, c, - fast channel blockers
lidocaine |
|
|
antidysrhythmic class II |
II- beta blockers (also used for HTN)
metoprolol, atenolol |
|
|
antidysrhythmic class III |
III- sodium channel blockers (prolong repolarization)
amiodarone (common for dysrhtmias) |
|
|
antidysrhythmic class IV |
calcium channel blockers
diltiazem, verapamil (decreases contractility) |
|
|
antidysrhythmic others |
slow SA automaticity, AV conduction
digoxin, adenosine (given for fast HR quickly IVP) |
|
|
valsalva maneuver |
to stimulate vagal nerve "bear down" ...doesn't always work |
|
|
carotid sinus massage |
MD ONLY can cause worse dysrhythmias |
|
|
synchronized cardioversion |
normally elective important is pre/post care |
|
|
defibrillation |
used in pt's w/v-fib, v-tach *pt must have SOME electrical activity |
|
|
pre/post care w/sync cardioversion |
labs- chk electrolytes! consent, IV, tele conscious sedation manage airway |
|
|
pacemakers most common patients |
elderly |
|
|
pacemaker function |
manage dysrhythmias provides impulse when no electrical activity is detected stimulates heart if drops <60 |
|
|
post pacemaker insertion care |
minimal overhead mov't of arm monitor pacer minor pain control CXR- for lead placement & pneumothorax |
|
|
complications w/pacemaker |
infection bleeding at site pacer malfunction perforation tamponade pneumothorax |
|
|
pacemaker home care |
teach infection s&sx Tylenol-pain control carry ID card always cell phone on opposite side, no MRI or strong magnetic field pacer checks from home q3 mos. |
|
|
pacemaker homecare w/bathing & activity |
shower after 5 days no soak no>10 lbs for 1st month no driving 2-4 wks |
|
|
pacer malfunction s&sx |
dizzy, fatigue, palpitations, weakness, chest pain, pulse checks |
|
|
difference between pacer and ICD |
pacer- senses HR, paces if HR < 60 bpm
ICD- senses HR AND rhythm, fires if chg in rhythm (15-30 sec=electrical chg 25-30 joules) |
|
|
catheter ablation used for |
can result in cure of dysrhythmia
if can't get pt to stay in regular rhythm, can take more that one time |
|
|
what is catheter ablation |
use radio frequency burn ectopic area |
