True or false
100
What does "Brady" mean?
slow
100
How big is the heart approximately?
The heart is approximately the size of one's fists.
100
I am a complex that is associated with ventricular contraction, what am I?
I am the QRS complex.
100
What is the leading cause of death?
Coronary Vascular Disease (CVD)
200
What does the term contraction mean?
An electrical impulse was conducted and allowed the heart to allow blood flow from the atria to ventricles.
200
How is the heart divided?
The heart is divided into two sides (Right and Left) and Four Chambers.
200
You can usually recognize me at the end of the normal sinus rhythm. I allow the heart time to relax. What Wave am I?
I am the T wave
200
In the hospital, a 12-lead ECG is done as a routine procedure or during an emergency such as a code blue.
True
300
What does Sinus mean?
Normal configuration of P wave, QRS complex, and T wave.
300
1. What are the top chambers called? 2. What are the bottom Chambers called?
1. Atria 2. Ventricles
300
I am associated with atrial contraction, without a proper impulse from the SA node I am non existent, what am I?
I am the P wave.
300
Two other ECG-type test may be performed in an office include treadmill stress testing and the ambulatory monitor or Holter monitor testing.
True
400
what does the term Automaticity mean?
The ability for the heart to conduct or create its own electrical impulse.
400
What are the names of the Pacemakers in the heart, and what is their intrinsic firing rate?
SA node - 60-100 Av Node - 40 - 60.
400
What would you see if the SA node didn't fire?
No P wave; QRS or QRS and T only.
400
What allows ECG's to be done outside of the medical environment?
AED Machine
500
Why is Electrocardiogram called an Electrocardiogram?
Electric (Electro) , Cardiac (Cardio) , Tracing(Gram)
500
How does the blood circulate throughout the heart?
Deoxygenated blood ----> Right Atrium ------> Tricuspid valve ----> Right Ventricle ----> pulmonic valve -----> Lungs (Oxygenated blood) ----> Left Atrium ----> Mitril/Bicuspid valve ----> Left Ventricle ----> Aortic valve ---> Aorta ----> out the body
500
I am slower than the normal sinus rhythm, but yet can still be called normal in athletic individuals. What rhythm am I?
I am the Sinus Arrhythmia.
500
There is 12 electrodes that get placed on a patient when doing an ECG?
False.
