Adult II Exam #1 Review

The purposeful destruction of heart muscle cells in an attempt to eliminate an arrhythmia

• Ablation

• Defibrillation

• Cardioversion

• CRT

An electrical current given to stop an arrhythmia, not synchronized with the patient's QRS complex:

An electrical current given to stop an arrhythmia, synchronized with the patient's own QRS complex:

The part of an ECG that represents atrial depolarization

(conduction of an electrical impulse through the atrium)

• P Wave

• QRS Complex

• T Wave

• U Wave

The part of an ECG that represents ventricular depolarization

(conduction of an electrical impulse through the ventricles)

• P Wave

• QRS Complex

• T Wave

• U Wave

The part of an ECG that represents repolarization of the ventricles

• P Wave

• QRS Complex

• T Wave

• U Wave

The part of an ECG that may reflect Purkinje fiber repolarization

(but is not usually seen unless the patient has hypokalemia)

• P Wave

• QRS Complex

• T Wave

• U Wave

Used to calculate atrial rate and rhythm

• PP Interval

• RR Interval

• QT Interval

• TP Interval

Used to calculate ventricular rate and rhythm

• PP Interval

• RR Interval

• QT Interval

• TP Interval

Reflects the time from ventricular depolarization through repolarization

• PP Interval

• RR Interval

• QT Interval
