Basic ECG InterpretationArrhythmia(dysrhythmia): - ANS- do not surprise!
- provide meds (epinephrine)
- PEA (pulseless electrical pastime)
PEA(pulseless electrical activity): - ANSNo room for diastole
- pulse is going down
- Ex: cardiac tamponade(stress on coronary heart whilst fluid or blood build up between
myocardium & pericardium), contamination
3 Life threatening dysrrhythmias: - ANS1. V-fib
2. V-tach
3. Torsade de Pointes
What is the shortest distance? - ANSSA node to the perkinje fibers
Diastole: ventricles ____ - ANSRelax
Systole: ventricles ____ - ANScontract
P-wave: - ANSatrial depolarization
- anticipate atrials to contract
QRS complicated: - ANSventricular depolarization
- assume ventricles to agreement
T-wave: - ANSventricular repolarization
SA(sinoatrial) node - ANSDominant pacemaker of the heart, positioned within the higher
portion of the proper atrium. Intrinsic charge: 60-a hundred bpm
Internodal pathway: - ANSDirect electric impulses between SA and AV nodes
Bachman's Bundle: - ANSDirect electrical impulses from the SA node to the left atrium
Atrioventricular (AV) node: - ANSPart of the AV junctional tissue. Slows conduction, creating
a moderate put off earlier than impulses reach ventricles. Intrinsic fee: forty-60 bpm
Bundle of His: - ANSTransmits impulses to package deal branches. Located underneath AV
node
Left Bundle branch - ANSConducts impulses that lead to left ventricle
Right package department - ANSconducts impulses that lead to proper ventricle
, Purkinje device: - ANSNetwork of fibers that spreads impulses hastily during ventricular
partitions. Located at terminal bundle branches. Intrinsic charge: 20-forty bpm
CHronic A-fib: - ANSCoumadin QD
- take a look at PT & INR
- doesn't assist with rhythm
- helps save you clots
As energy goes down pathway, pulse... - ANSgoes down
Purkinje fibers: - ANSSarcomeres of coronary heart have plenty of branches to offer
mechanical response
Sympathetic Nervous System: - ANS- fight or flight
- increase HR
- dilate scholars, inhibit saliva, dilate bronchi, inhibit peristalsis, convert glycogen to glucose,
secretion of adrenalin & noradrenaline, inhibit bladder contraction
Medications: epinephrine
Parasympathetic: - ANS- lower HR
- stimulates go with the flow of saliva, constricts bronchi, stimulate peristalsis, stimulate
release of bile, constrict bile
Depolarization: - ANSthe electric charge of a cell is altered by a shift of electrolytes on either
facet of the cell membrane. This alternate stimulates muscle fiber to settlement
Repolarization: - ANSChemical pumps re-establish an inner poor price as the cells return to
their resting country
Automaticity: - ANSAbility to initiate an impulse spontaneously and continuously
Excitability: - ANSAbility to be electrically inspired
Conductivity: - ANSAbility to transmit an impulse along a membrane in an orderly manner
Contractility: - ANSAbility to reply robotically to an impulse
Inotropic: - ANSstrength of contraction
Chronotropic: - ANSrate of contraction (how fast/sluggish)
Dromotropic: - ANSspeed of conduction
Digoxin: - ANSMedication, will increase strength of contraction, lowers rate & pace
ECG - ANS- A collection of waves and deflections recording the heart's electrical activity
from a sure view or lead.
