Unit 5 Cardiac Dysrhythmiasdysrhythmia - answer a conduction disorder that results in an abnormally slow or rapid
HR or one that does not proceed through the conduction system in the usual manner
sinus bradycardia - answer a dysrhythmia that proceeds normally through the
conduction pathway but at a slower than usual rate
sinus tachycardia - answer a dysrhythmia that proceeds normally through the
conduction pathway but at a faster rate than normal
premature atrial contraction - answer neural tissue in the atrial conduction system
initiates an early electrical impulse
ectopic pacemaker site - answer initiates an electical impulse independently of the SA
node
supraventricular tachycardia(SVT) - answera dysrhythmia in which the HR has a
consistent rhythm but beats at a dangerously high rate
atrial flutter - answera disorder in which a single atrial impulse outside the SA node
causes the atria to contract at an exceedingly rapid rate
atrial fibrillation - answerseveral areas in the right atrium initiate impulses resulting in a
disorganized, rapid activity. The ventricles quiver rather than contract.
chemical cardioversion - answeruse of drugs to eliminate a dysrhythmia
maze procedure - answersurgical procedure to treat atrial fibrillation in which a new
conduction pathway is created that eliminates the rapid firing of ectopic pacemaker sites
in the atria
heart block - answerrefers to disorders in the conduction pathway that interfere with the
transmission of impulses from the SA node through the AV node to the ventricles.
premature ventricular contraction(PVC) - answerventricular contraction that occurs early
and independently in the cardiac cycle before the SA node initiates an electric impulse
ventricular tachycardia - answercaused by a single, irritable focus in the ventricle that
initiates and then continues the same repetitive
ventricular fibrillation - answerthe rhythm of a dying heart
