Premature atrial contraction (PAC)
Premature ventricular Contraction (PVC)
o randomised & bizarre wide QRS
ectopic beats: abnormal beats either atrial or ventricular
Sinus tachycardia: normal hardly > lay
Sinus bradycardia: normal save < rate
Bundle branch block: indicates conduction defect
oQRS ?0.12.
oPressence of P wave indicates complex didnt break in ventricles
Atrial flutter
oNo P waves, but have F (flutter) waves
oSignal avoids SA node.
o travel rapidly rate: 250-350 beats/min
oSome what regular proportionality of flutters:QRS
Atrial fibrillation
oNo P waves, irregular with irregular R-R intervals.
oNo logical pattern
oQRS is in normal range
oD/t random electrical venting in atria
Supraventricular tachycardia
oDysrhythmia that originates above the AV node
o non specific
oUsually used for rapid, sustained atrial/junctional tachycardia
oRate increased, QRS normal, Cant definitely define P waves, depressed ST seg
Ventricular tachycardia
oVentricular site tone ending at rate of 100 times or more/min
oQRS is wide
oMay or may non see P wave
Ventricular Fibrillation
od/t chaotic electrical activity in ventricles from repetitive pocket-sized areas of reentry or series of rapid d/cs from miscellaneous foci quiver
oNo clear P, QRS, or T wavesPatient doesnt have a pulse, no blood is universe pumped, and defibrillation is only definitive therapy
oMust implement adjunct measures
3rd degree Atrioventricular Block
oNo atrial impulses can conduct from atria to ventricles
oP waves present and unremarkably regular
oIF junctional focus: normal QRS but at rate/timing totally independent.
oPR vary.
oIf ventricular focus: QRS is wide and unrelatedIf you want to get a full-of-the-moon essay, order it on our website: Orderessay
