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
