|
Sinus rhythm
|
originates from SA node, 60-100 bpm
|
|
|
Sinus Bradycardia interventions
|
Treat if symptomatic
oxygen Atropine Sulfate to increase HR Monitor for hypotension, IV fluids pacemaker may be needed |
|
|
Sinus Tachycardia interventions
|
treat the cause, rest, oxygen, fluids, diuretics, digoxin, BB
|
|
|
A-Fib
|
IRREGULAR, no atiral kickdisorganized firing of impulses, HR 120-130 bpm; atria quiver leading to thromi formation
no definitive p wave, not lethal Hypertension, CHF,COPD, MI< CAD |
|
|
A-fib interventions
|
oxygen
anticoagulants cardioversion medications to slow the rate |
|
|
V-tach
|
100-200 bpm,can turn in v-fib
repetitive firing PVC's in a row can cause cardiac arrest Dig toxicity, hypokalemia, hypocalemia, caffiene, CHF |
|
|
V-tach interventions
|
Stable- oxygen, antidysrythmics
Unstable- oxygen, antidysrythmics, cardioversion, CDB Pulseless-defibrilate,CPR |
|
|
V-fib
|
Ventriles quivering, disorganized impulses, fatal if not terminated within 3-5 minutes
MI hypo/hyperkalemia, hypocalemia |
|
|
V-fib interventions
|
defibrillate, CPR, oxygen, epinephrine,antidysrythmics,amiodarone
|
|
|
Cardioversion
|
synchronized countershock to convert undesirable rhythms, low amounts of energy
|
|
|
Defibrillator
|
asyncronous countershock for VT or VF, high energy
|
|
|
Implantable Cardioverter defibrillator (ICD)
|
monitors cardiac rhythms, for VT and VF
|
|
|
Pacemaker
|
electrical stimulation to maintain the HR
|
|
|
Sinus Bradycardia
|
sleep, hypothermia, hypothyroidism, CCB,BB, elevated ICP
|
|
|
Sinus Tachycardia
|
fever,anxiety, caffiene, nicotine, alcohol,hypotension, CHF
|
|
|
Depolarization
|
NA goes into the cell; CA,K,MG come out of the cell
|
|
|
Nervous System
|
Sympathetic- increases HR
Parasympathetic- slows HR |
|
|
Normal PR interval
|
.12-.20 seconds
|
|
|
Normal QRS complex
|
.06-.12 seconds
