QRS complex - ANSWER ✓ represents ventricular depolarization
T- wave - ANSWER ✓ represents the period of ventricular repolarization on the
ECG
Heart rate - ANSWER ✓ normal rate for an adult is between 60-100 bpm
Tachycardia - ANSWER ✓ Heart rates above 100
Bradycardia - ANSWER ✓ heart rates below 60
T Wave Interpretation - ANSWER ✓ The T wave is known as the resting phase of
the cardiac cycle
U Wave Interpretation - ANSWER ✓ represent repolarization of the Purkinje
fibers and are called Late ventricular repolarization waves
Artifacts - ANSWER ✓ can be caused by patient movement, shivering, muscle
tremors, or loose electrodes.
Supraventricular Tachycardia - ANSWER ✓ Regularity: regular; P-wave: cannot
be identified; QRS-complex: normal ; PR-interval: absent
Atrial flutter - ANSWER ✓ Regularity: may be regular or irregular; P-wave:
absent (flutter waves); QRS-complex: normal; PR-interval: absent
, Atrial fibrillation - ANSWER ✓ Regularity: irregularly (totally) irregular; P-wave:
absent (chaotic baseline); QRS-complex: normal; PR-interval: absent
Types of Junctional Dysrhythmias - ANSWER ✓ Regularity: occasional or
frequently irregular depends on the number of PJCs; ORS-complex: Normal; PR
Interval: short or absent
Junctional escape rhythm - ANSWER ✓ Regularity: Regular; P-wave: inverted,
absent, or occur after the QRS-complex; QRS-complex: normal; PR-interval: short
or absent
Accelerated Junctional Rhythm - ANSWER ✓ Regularity: regular ; HR : 60 - 100
; P-wave: inverted, absent, or occur after the QRS-complex ; QRS-complex:
normal ; PR-interval: short or absent
Junctional Tachycardia - ANSWER ✓ Regularity: regular; HR: above 100; P-
wave: inverted, absent, or occur after the QRS-complex; PR-interval: short or
absent - less than 0.12 seconds
Ventricular Dysrhythmias - ANSWER ✓ Some may be benign while some may be
life threatening.
Idioventricular Rhythm: - ANSWER ✓ Regularity: regular; HR: 20-40; P- wave;
absent; QRS - complex: wide and bizarre; PR - Interval: absent
Accelerated Idioventricular Rhythm: - ANSWER ✓ Regularity: regular; HR: 40-
100; P - wave: absent; QRS - complex: wide and bizarre; PR - interval: absent
Ventricular Tachycardia (may have a pulse or may not): - ANSWER ✓
Regularity: regular; P - wave: absent; QRS - complex: wide and bizarre; PR -
interval: absent
Ventricular Tachycardia (may have a pulse or may not): - ANSWER ✓
Polymorphic ventricular tachycardia (Torsade de Pointes) QRS complexes
alternate between upright and downward deflections
