ECG ANALYSIS RHYTHM RECOGNITION RELIAS
COMPREHENSIVE PAPER 2026 EXAM GUIDE
WITH QUESTIONS WITH ANSWERS GRADED A+
what are the layers of the heart and their functions? Correct
Answer fibrous pericardium
parietal layer(serous)
pericardial cavity
visceral/epicardium(serous)
what is the role of the fibrous peridcardium Correct Answer limits
the motion of the heart and prevents over distention when the
heart contracts, anchors the heart in the mediastinum, protects
the heart
how many layers does the serous pericardium have and what
does it do ? Correct Answer two layers, helps lubricate the heart
to reduce friction between layers
what are the two layers of the serous pericardium? Correct
Answer parietal layer and visceral layer, or epicardium
,what is the space between the parietal layer and visceral layer
called? Correct Answer the pericardial cavity
what major components run down the heart within the
epicardium? Correct Answer the left and right coronary arteries
what can be found within the pericardial space Correct Answer 15
to 50 ml of pericardial fluid
where is the heart located in the chest? Correct Answer between
the lungs in the mediastinum
where is majority of the heart located Correct Answer left of the
midline
what is the outer layer of the pericardium called Correct Answer
fibrous pericadium
what is significant about the myocardium(middle layer) Correct
Answer comprised of involuntary striated muscle, it is this layer
that contracts to pump blood
what can be found in the endocardium(inner most layer of the
heart) Correct Answer Purkinje Fibers
, what is the role of the Purkinje Fibers found in the endocardium?
Correct Answer depolarize surrounding cells to initiate a
contraction in the heart
how does the endocardial endothelial tissue play a vital role in
maintaining cardiac function? Correct Answer releases
compounds such as endothelin and nitrous oxide that influence
cardiac conduction, contraction, rhythm, and metabolism
what is endothelin Correct Answer a peptide, or small protein that
constricts blood vessels and raises blood pressure
what is the role of the right atrium of the heart? Correct Answer
receive deoxygenated blood from peripheral and coronary
circulation via the superior and inferior vena cava and the
coronary sinus
what is the role of the right ventricle of the heart? Correct Answer
receives deoxygenated blood from the right atria via the tricuspid
valve and pumps this blood into pulmonary circulation via the
pulmonary valve
what is the role of the left atrium and the cardiac cycle Correct
Answer receive oxygenated blood from the pulmonary veins and
