,Abstract
This EMT FISDAP Cardiology Exam document for the 2026/2027 cycle reflects the standardized
assessment used to evaluate competency in prehospital cardiac care. The examination measures
knowledge of cardiovascular physiology, cardiac emergencies, ECG interpretation, resuscitation
protocols, pharmacologic interventions, and evidence-based EMS practices required for effective
emergency response. All 100 questions are presented in bold, with correct answers highlighted in bold
green. Detailed rationales in italics explain the clinical reasoning, pathophysiology, and evidence-
based guidelines supporting each answer. This examination aligns with current American Heart
Association guidelines and FISDAP testing standards.

Introduction
The EMT FISDAP Cardiology Examination is a comprehensive assessment designed to evaluate the
knowledge and clinical decision-making skills essential for emergency medical technicians in the
cardiac care setting. This examination covers ten core domains ranging from foundational
cardiovascular anatomy and physiology to advanced EMS protocols. Questions are formatted to reflect
real-world clinical scenarios encountered in prehospital emergency care, requiring integration of
pathophysiologic knowledge, assessment findings, and evidence-based treatment protocols. Each
question has been verified and elaborated with detailed rationales to enhance learning and clinical
application.

• Correct answers are presented in bold green
• All rationales are written in italic font
• Select the single best answer for each question
Cardiovascular Anatomy & Physiology
Question 1
Which chamber of the heart is responsible for pumping oxygenated blood to the
systemic circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
, D. Left ventricle
Correct Answer: D. Left ventricle
Rationale: The left ventricle is the primary pumping chamber of the heart, responsible for
ejecting oxygenated blood into the aorta and systemic circulation. Its walls are thicker
(approximately 3 times) than the right ventricle due to the higher pressures required for
systemic perfusion.
Question 2
The coronary arteries primarily fill during which phase of the cardiac cycle?
A. Systole
B. Diastole
C. Isovolumetric contraction
D. Isovolumetric relaxation
Correct Answer: B. Diastole
Rationale: Coronary artery perfusion occurs primarily during diastole when the myocardium
is relaxed. During systole, the contracting myocardium compresses the coronary vessels,
reducing blood flow. This is why tachycardia can compromise coronary perfusion—shortened
diastole reduces filling time.
Question 3
Which valve prevents backflow of blood from the aorta into the left ventricle?
A. Mitral valve
B. Tricuspid valve
C. Aortic valve
D. Pulmonary valve
Correct Answer: C. Aortic valve
Rationale: The aortic valve is a semilunar valve located between the left ventricle and the
aorta. It prevents backflow of blood during ventricular diastole. The mitral valve separates the
left atrium and ventricle, while the tricuspid separates the right atrium and ventricle.
Question 4
The electrical conduction system of the heart normally originates in which structure?
A. Atrioventricular (AV) node
B. Sinoatrial (SA) node
C. Bundle of His
D. Purkinje fibers
Correct Answer: B. Sinoatrial (SA) node
, Rationale: The SA node, located in the upper right atrium near the superior vena cava, is the
heart's primary pacemaker. It spontaneously depolarizes at a rate of 60-100 beats per minute,
initiating the electrical impulse that triggers atrial contraction.
Question 5
What is the normal resting cardiac output for an average adult?
A. 2-3 L/min
B. 4-6 L/min
C. 8-10 L/min
D. 12-15 L/min
Correct Answer: B. 4-6 L/min
Rationale: Cardiac output (CO) equals stroke volume multiplied by heart rate (CO = SV × HR).
In a healthy adult at rest, normal cardiac output ranges from 4-6 liters per minute. This can
increase up to 20-25 L/min during maximum exercise.
Question 6
Which blood vessel carries deoxygenated blood from the heart to the lungs?
A. Aorta
B. Pulmonary artery
C. Pulmonary vein
D. Superior vena cava
Correct Answer: B. Pulmonary artery
Rationale: The pulmonary artery is unique among arteries as it carries deoxygenated blood
from the right ventricle to the lungs for oxygenation. The pulmonary veins carry oxygenated
blood from the lungs to the left atrium.
Question 7
Starling's Law of the heart states that increased preload results in:
A. Decreased stroke volume
B. Increased stroke volume
C. Decreased heart rate
D. Increased afterload
Correct Answer: B. Increased stroke volume
Rationale: Starling's Law (Frank-Starling mechanism) states that the heart will pump
whatever volume is returned to it. Increased venous return (preload) stretches cardiac muscle
fibers, resulting in more forceful contraction and increased stroke volume, up to a physiologic
limit.
