Dysrhythmia Topics
disorder of impulse formation, conduction of impulses, or both (electrical problem) - correct answers
✔️✔️dysrhythmia
normal pacemaker of the heart; 60-100 BPM - correct answers ✔️✔️sinoatrial (SA) node
the AV node and purkinje fibers are... - correct answers ✔️✔️secondary pacemakers
represents atrial depolarization; means SA node is working and are in some type of sinus rhythm -
correct answers ✔️✔️P wave
represents ventricular depolarization; ventricles contracting - correct answers ✔️✔️QRS complex
represents ventricular repolarization; ventricles relaxing - correct answers ✔️✔️ST segment
ventricle repolarization - correct answers ✔️✔️T wave
, a dysrhythmia that has a sudden onset and terminates spontaneously; usually of short duration but may
recur - correct answers ✔️✔️paroxysmal
reflects the time from ventricular depolarization through repolarization - correct answers ✔️✔️QT
interval
reflects the conduction of an electrical impulse from the from the SA node through the AV node -
correct answers ✔️✔️PR interval
electrical current given in synchrony with the patients own QRS complex to stop a dysrhythmia - correct
answers ✔️✔️cardioversion
distorted, irrelevant, and extraneous ECG waveforms - correct answers ✔️✔️artifact
purposeful destruction of heart muscle cells in attempt to correct/eliminate a dysrhythmia - correct
answers ✔️✔️ablation
biventricular pacing used to correct inter ventricular, intraventricular, and atrioventricular conduction
disturbances that occur in patients with HF - correct answers ✔️✔c️ ardiac resynchronization therapy
(CRT)
transmission of impulses from one cell to another - correct answers ✔️✔c️ onduction
cardiac muscles change from more negative to more positive charge; electrical stimulation - correct
answers ✔️✔️depolarization
mechanical contraction is known as... - correct answers ✔️✔️systole
cardiac muscle cells change from more positive to more negative charge; electrical relaxation - correct
answers ✔️✔️Repolarization
mechanical relaxation is known as... - correct answers ✔️✔️diastole
