Cardiology Final Paramedic II(Correctly solved)
What is the term used to refer to the process of electrical discharge and the flow of electrical
activity? correct answersDepolarization
Explain the physiology of depolarization. correct answersOccurs when sodium rushes into the
cell, resulting in a positive electrical charge and the start of electrical current flow.
Explain cardiac resting potential. correct answersInside of the cell is more negatively charged
than the outside of the cell.
Explain cardiac action potential. correct answersInflux of sodium changes the membrane
polarity.
The left coronary artery branches into? correct answersAnterior descending and circumflex
Name the parts of the heart that the left coronary branch supplies. correct answersLeft ventricle,
interventricular septum, part of the right ventricle, and the heart's conduction system.
The right coronary artery branches into? correct answersPosterior descending and marginal
branch.
Name the parts of the heart that the right coronary artery supplies. correct answersA portion of
the right atrium and right ventricle and part of the conduction system.
Identify PVCs. correct answersInterrupts regular underlining rhythm. Single ectopic impulse.
QRS >.12, bizarre. May occur in patterns.
Describe hyperkalemia on an EKG. correct answersTall T-segments. Suspect in a pt with renal
failure.
Describe 12 lead placement. correct answersV1- 4th intercostal R of sternum.
V2- 4th intercostal L of sternum.
V4- 5th intercostal at L mid-clavicular.
V3- between V2 & V4.
V6- L mid-axillary.
V5- Between V4 & V6.
Describe junctional rhythms. correct answersMissing or inverted P-waves, normal QRS. May see
inverted P-wave after QRS.
What does I See All Leads stand for? correct answersInferior, Septal, Anterior, Lateral.
What is the area viewed and the focus of leads I, II, AVf? correct answersInferior wall LV and
RCA.
