    What is the "heart rate"?

    • A test for blood pressure build up

    • The number of times your heart beats a minute

    • The synchronised pumping action of your heart chambers

    • A test to seeif your heart is healthy

    Correct Answer
    A. The number of times your heart beats a minute
    Explanation
    The correct answer is "the number of times your heart beats a minute." Heart rate refers to the number of times the heart contracts or beats in a span of one minute. It is commonly measured as beats per minute (BPM) and is an essential indicator of cardiovascular health and fitness level. Monitoring heart rate can provide valuable information about the efficiency of the heart's pumping action and overall cardiac function.

    What is the name of the machine that can be used to reset the heart's natural beat?

    • ALD

    • EAD

    • IED

    • AED

    Correct Answer
    A. AED
    Explanation
    An AED (Automated External Defibrillator) is a machine that can be used to reset the heart's natural beat. It is a portable device that delivers an electric shock to the heart in cases of cardiac arrest, helping to restore normal heart rhythm. AEDs are commonly found in public places such as airports, schools, and shopping malls, and they are designed to be user-friendly, providing step-by-step instructions to guide even non-medical personnel in their use.

    When  the SA node" fires" it triggers the following process

    • TrueThe electrical signal travels from your SA node through muscle cells in your right and left atria

    • False The electrical signal travels from your SA node through muscle cells in your right and left ventricles

    Correct Answer
    A. TrueThe electrical signal travels from your SA node through muscle cells in your right and left atria
    Explanation
    The SA node, also known as the sinoatrial node, is responsible for initiating the electrical signals that regulate the heartbeat. When the SA node "fires," it triggers a series of events that cause the atria, the upper chambers of the heart, to contract. The electrical signal travels through muscle cells in the right and left atria, causing them to contract and pump blood into the ventricles. Therefore, the correct answer is that the electrical signal travels from the SA node through muscle cells in the right and left atria.

    What controls the timing of your heartbeat?

    • Heart pressure

    • Heart muscles

    • Heart's electrical system

    • Normal steady heartbeat

    Correct Answer
    A. Heart's electrical system
    Explanation
    The timing of the heartbeat is controlled by the heart's electrical system. This system includes specialized cells that generate electrical signals, which travel through the heart and regulate the contraction and relaxation of the heart muscles. These electrical signals ensure that the heart beats in a coordinated and rhythmic manner, pumping blood effectively throughout the body. Any disruption or abnormality in the heart's electrical system can lead to irregular heartbeats or arrhythmias.

    What does the  normal heart rate at rest range between per minute?

    • 40 - 70

    • 60 - 70

    • 80 - 100

    • 60 - 100

    Correct Answer
    A. 60 - 100
    Explanation
    The normal heart rate at rest can vary between 60 and 100 beats per minute. This range is considered to be within the normal range for a healthy individual at rest. Heart rate can be influenced by factors such as age, fitness level, and overall health. It is important to note that individual variations may exist, and it is always best to consult with a healthcare professional for personalized advice.

    What is the "bundle of His"?

    • The heart's pacemaker

    • Conduction cells which respond to the electrical signal from the atrioventricular node

    • Male electrical cells that pump the heart

    • The cells inside the sinoatrial node that create the heartbeat

    Correct Answer
    A. Conduction cells which respond to the electrical signal from the atrioventricular node
    Explanation
    The "bundle of His" refers to conduction cells which respond to the electrical signal from the atrioventricular node. These cells play a crucial role in transmitting the electrical impulses from the atrioventricular node to the ventricles, allowing for coordinated contraction and pumping of blood throughout the heart.

  • 8. 

    What is "sinus rhythm"?

    • Orderly contraction of your atria and ventricles

    • Normal breathing through the nasal passage airways.

    • Abnormal heart rate

    • Your atria and ventricules contracting all at the same time

    Correct Answer
    A. Orderly contraction of your atria and ventricles
    Explanation
    Sinus rhythm refers to the normal electrical activity of the heart, where the atria and ventricles contract in a coordinated and organized manner. This rhythm is responsible for maintaining a regular heartbeat and efficient blood circulation throughout the body. It is considered the standard rhythm of a healthy heart.

    Where is the AV "Atrioventricular" node

    • Left ventricle

    • Right atrium

    • Right ventricle

    • Left atrium

    Correct Answer
    A. Right atrium
    Explanation
    The AV (Atrioventricular) node is located in the right atrium. It is a small bundle of specialized cells that acts as a bridge between the atria and ventricles in the heart. It receives electrical signals from the atria and delays them before transmitting them to the ventricles, allowing for coordinated contraction and efficient pumping of blood.

    The eletrical signal travels through the network of conducting cell"pathways" It starts in a group of cells at the top of your heart called

    Correct Answer
    sinoatrial node SA
    Explanation
    The electrical signal that initiates the heartbeat travels through a network of conducting pathways in the heart. This signal starts in a group of cells located at the top of the heart called the sinoatrial node (SA node). The SA node acts as the natural pacemaker of the heart, generating electrical impulses that regulate the heart's rhythm. These impulses then spread through the atria, causing them to contract and pump blood into the ventricles. From there, the signal travels to the atrioventricular node (AV node) and then to the rest of the heart, coordinating the contraction of the ventricles and ensuring efficient blood circulation.
