hollow, muscular organ
What is the heart?
100
A test that measures the electrical activity of the heartbeat.
What is "EKG/ECG"?
100
What is considered the pacemaker of the heart?
What is "The SA node"
100
Purpose of a pacemaker
What is "to send tiny electric signals to your heart if heart beat is too slow"?
200
Function of the Heart
What is "to pump blood through the blood vessels of the body, providing each cell in the body with nutrients and oxygen"?
200
What does EKG/ECG stand for?
What is "electrocardiogram"?
200
On average, how many times is a cardiac impulse fired?
What is "72 times per minute"
200
What does AED stand for?
What is "Automated External Defibrillator"?
300
Define pulmonary circulation
What is " deoxygenated blood--->right side of the heart---> lungs--> left side of the heart"?
300
The first wave of an EKG (represents upper chambers).
What is "P wave"?
300
What causes the electrical signal in the cells of the SA node?
What is "The action potential caused by electrolytes"
300
FREEBIE
What is "YAY"?
400
thickest layer of the heart composed of cardiac muscle which allows the contraction of the heart
What is "myocardium"?
400
What does the final "T wave" represent?
What is "electrical recovery or return to a resting state for the ventricles"?
400
The SA node, AV node, and Purkinje fibers can be considered as what?
What are "Resistors"
400
T/F: Someone with an ICD should be careful of surrounding electronic devices.
What is "True"?
500
How do blood flow through the heart?
What is "superior/inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, (LUNGS), pulmonary vein, left atrium, bicuspid valve, left ventricle, aortic valve, aorta"?
500
What can be determined by measuring time intervals of the EKG?
What is "if the electrical activity of the heart is normal, slow, fast, or irregular"?
500
Blood flow from the heart to the organs is in what arrangement?
What is "Parallel"
500
Why should people with helpful devices be cautious of surrounding devices?
What is "there's an electric field from the device that interferes with the signals given by the helpful devices"?
