FREC 4 ECG Exam Questions and
Answers 100% PASS
ST Elevation Myocardial Infarction (STEMI) - CORRECT ANSWER-
normal sinus rhythm (NSR) - CORRECT ANSWER-regular rhythm of the heart
cycle stimulated by the SA node (average rate of 60-100 beats/minute)
premature ventricular contraction (PVC) - CORRECT ANSWER-a ventricular
contraction preceding the normal impulse initiated by the SA node (pacemaker)
1st degree AV block - CORRECT ANSWER-Regular
Rate: 60-100
P Wave: Present, upright
PR interval: >0.20 sec CONSISTENTLY LONG
QRS: <0.12 sec
Asytole - CORRECT ANSWER-When no rhythm or electrical current is traveling
through the cardiac conduction system
ventricular fibrillation - CORRECT ANSWER-Disorganized, ineffective twitching
of the ventricles, resulting in no blood flow and a state of cardiac arrest.
