Review of Section 4 : Self-test

This page is best viewed with Internet Explorer. Position your mouse over the answer button and the answer to the question will appear.

 1. What is an EKG used for?  monitor a patient’s heart rate, evaluate the effects of disease or injury on heart function, evaluate pacemaker function, evaluate the response to medications, and obtain a baseline recording before, during, and after a medical procedure.

 2. What is the first wave recorded and what does it show? The first wave detected on the electrocardiogram is the P wave, at contraction of the atria.

 3. Define SYSTOLE and DIASTOLE. Systole is the contraction phase, diastole is the filling phase of a cardiac chamber.

 4. What does the T wave represent? The T wave represents the repolarization of the ventricles.

 5. What events comprise a cardiac cycle?  A cardiac cycle represents atrial systole, ventricular systole (contraction), and the resting stage between beats.

 6. Name the 6 limb leads.   I, II, III, AVR, AVL, AVF and meet to form six neatly intersecting reference lines which lie in a flat plane on the patient's chest, the frontal plane.

 7. Name the 6 chest leads.  The chest leads numbered from V1 through V6 move in successive steps from the patient's right to his left side. V1 and V2 are over the right heart, V3 and V4 are over the septum, V5 and V6 are over the LV.

 8. What is a “standard” lead setup?  The right and left arm leads are placed on the forearms and the right and left leg leads are placed on the lower legs above the ankles.

 9. Name the sequence of five characteristics of the baseline ECG that are checked prior to beginning a stress test.  rate, rhythm, axis, hypertrophy, infarction

10. What is sinus tachycardia?  Sinus Tachycardia is a steady rhythm that originates in the SA node and is greater than 100 bpm.

11. What is sinus bradycardia?  Sinus Bradycardia is a steady rhythm originating from the SA node, but is less than 60 bpm.

12. What is an ectopic focus?  Ectopic foci occasionally emit an electrical impulse in non-emergency situations, especially in heart disease.
