EKG quiz

1. What is the Hearts Dominate Pacemaker?
2. this represents the final rapid phase of ventricular repolrization
3. this Side of the heart receives un-oxygenated blood from the all over the body
4. This Represents atrial depolarization on an EKG
5. Which side is the tricuspid valve?
6. where is the atria repolarization hidden?
7. Which side is the mitral valve?
8. this is one complete heart beat
9. What represents electrical activity of both atria?
10. The SA node pace-making activity is known as what?
11. this represents depolarization of the ventricular system?
12. Which segment on an EKG can diagnose a MI?
13. how many blocks does it takes on EKG paper to represent 0.2 seconds?
14. when examining an EKG what should we determine first?

1. The SA node
2. t wave
3. Right side
4. the P wave
5. right
6. the QRS complex
7. left
8. the cardiac cycle  or the p wave, the qrs wave and the T wave
9. the P wave
10. sinus rhythm
11.  QRS complex
12. ST segment
13. 5
14. The rate

Matching

1. sinus rhythm
2. sinus bradycardia
3. sinus tachycardia
4. sinus arrhythmia
5. wandering pacemaker
6. atrial fibrillation
7. premature ventricular contraction
8. a run of 3 PVC’s
9. Paroxymal ventricular tachycardia
10. arial flutter
11. atrial fibrillation
12. v flutter
13. v fib
14. v-tach
15. fibrillation

1. sinus rhythm greater than 100/min
2. irregular rhythm; P wave shape will vary; rate less than 100; irregular ventricular rhythm (each pacing site takes a turn)
3. 60-100/min; equal distance b/w similar waves sinus
4. rate 350 – 450; totally erratic and rapid discharge from numerous automaticity focus from atria or ventricle
5. 350 – 450 rate caused by rapid rate discharges from many irritable automaticity foci producing a rapid, erratic waves and lack of any identifiable waves on the EKG strip
6. sinus rhythm less than 60/min
7. normally varies with respirations
   1. Abnormal but normal increase & decrease in rate upon respirations
8. irregular rhythm; continuous chaotic atria spikes; irregular ventricular rhythm
9. almost always) goes into V-flutter and this (almost always) turns into V-fib
10. rate 250 –350; produced by single ventricular automaticity focus firing rapidly and waves are wavy and smooth edged and all look alike.
11. 350 – 450; caused by many irritable atrial foci firing at rapid rates producing an extremely fast atrial rhythm, so erratic P wave (notice the ventricular response. Hopping in and out when they can).
12. rate of 250 – 350; atrial flutter originates in atrial automaticity focus. P waves (or flutter waves) occur in rapid succession/each identical to next.
13. rate of 150 – 250; characteristic pattern has an enormous consecutive PVC like complexes
14. PVC – originates suddenly in an irritable ventricular automaticity focus and produces a giant ventricular complex in an EKG (an enormous ventricular complex that is much wider, taller, and deeper than a normal QRS)
