CORRECT.
◉ First Degree AV Block, the PR interval is constant and measures
greater than 0.20 second. Answer:
◉ Second Degree AV Blocok Mobitz I (Wenkebach) has a cyclical
prolonging PR interval until the QRS is dropped. Then the cycle begins
again. ***Remember the clue "lengthen, lengthen drop Wenkebach.
Answer:
◉ Second Degree (AV) Block has a constant PR interval with blocked
QRS complexes. Answer:
◉ Second Degree (AV) Block has a constant PR interval with blocked
QRS complex (2). Answer:
◉ Third Degree (Complete) Heart Block, the P-P and R-R intervals are
regular (constant) but firing at different rates. Answer:
◉ T wave inversion, or negatively deflected T wave indicates ischemia
and is usually seen with ST segment elevation. Answer:
, ◉ T wave inversion with ST elevation on a 12-lead ECG is considered
myocardial injury, acute injury pattern, or acute. Answer:
◉ Physiologic Q wave is normal and the width measures less than 0.04
second and the depth measures less than one-third of the height of the R
wave in that lead. Answer:
◉ Pathologic Q wave indicates tissue death (infarction) and is defined as
measuring 0.04 second and/or greater than or equal to one third the
height of the R wave in that lead tracing. Answer:
◉ Ventricular Tachycardia has wide and bizarre QRS complexes with a
classic "sawtooth" appearance, a rate in excess of 100 bpm, with no P
wave. Answer:
◉ Ventricular fibrillation is the absence of organized electrical activity.
There are no P waves, QRS complexes or T waves. The tracing has a
chaotic or disorganized appearance. Answer:
◉ Asystole is absence of ventricular activity and depolarization. Often
this is called "the straight flat line" of rhythms. No electrical activity is
present. This rhythm is neither regular or irregular. It is simply absent!.
