COMPLETE QUESTIONS AND ANSWERS.
◍ what is AVL ? Ans: AVL is the difference in the hearts voltage
◍ what is AVF? Ans: AVF is the difference in the hearts voltage
between the left leg and midpoint between left leg and right arm
◍ what does V1 through V6 record? Ans: V1 through V6 records hearts
voltage from the front to the back of the heart, recorded from the central
point of the heart
◍ What is a sinus arrhythmia? Ans: it is changes in breathing
◍ what does the term systole mean? Ans: flatline (death)
◍ what is a heart murmur? Ans: a heart murmur is the sound of a faulty
action when the valves close
◍ what is ischemia. Ans: it is death to an area of the heart
,◍ when someone feels pain in the heart its because? Ans: when
someone feels pain in the heart it is because inadequate blood flow to the
heart muscle
◍ what does MI stand for? Ans: MI stands for a myocardial infarction
◍ what is one of the major causes of heart failure? Ans: one of the
major causes of heart failure is untreated blood pressure
◍ What is a myocardial infarction? Ans: a myocardial infarction is
when the myocardial tissue suffers death to an area because of
insufficient heart blood flow

◍ what is the internal pacemaker of the heart ? Ans: SA Node
◍ the lower pumping chambers of the heart are called? Ans: ventricles
◍ what happens when the atria contracts? Ans: the ventricles fill
◍ the upper pumping chambers of the heart are called? Ans: the atria
◍ where is the AV bundle located? Ans: it is located at the top of the
septum
◍ where is the heart located? Ans: it is located in the center of the chest
(more towards the left)
