Lesson 1 ECG

Information on Quiz 1

avR

avL

avF

-augmented lead toward the right arm

-augmented lead toward the left arm

-augmented lead toward the foot

Bundle of His(AV bundle)

-are a group of muscle fibers in the heart are crucial for electrical conduction.

-is not working if R- is short

Calculating Heart Rate

1.Count the number of large squares within one R-R interval

2. Divide 300 by the number of large squares

Calculating QRS complexes

1. count the number of QRS complexes on rhythm strip.

2. Multiply the number complexes by six.

Ventricular fibrillation(V-fib)

is a dangerous heart rhythm where the lower chambers of the heart shake instead of pumping blood effectively.

Ventricular Techcardiya(v-tech)

 is made when there is a disruption in the hearts normal electrical signaling within the lower chambers(ventricles). This causes the heart to beat too fast.

Ventricular A systole

flat line

Types of Heart Blocks:1st degree AV(atrioventricular) block

occurs when electrical signals from the atria to the ventricles are delayed.

Types of Heart Blocks:Second-Degree AV block Mobitz Type 1

the electrical signal from the atria to the ventricles is intermittently blocked.

Types of Heart Blocks:Second Degree AV block Mobitz Type 2

a heart rhythm disturbance where some electrical impulses from the atria fail to reach the ventricles, causing skipped heartbeats.

Types of Heart Blocks:Third Degree AV block(complete)

is a serious heart condition where electrical signals from the atria cannot reach the ventricles.

Artificial Pacemaker Rhythm

70 bpm

a P wave before QRS is absent

Lead

is a glimpse of electrical activity of the heart from a certain angle.

When does hand washing happen?

-before touching a patient, before clean/aseptic procedure, after body fluid exposure risk, after touching a patient, and after touching patient surroundings.

Biohazard waste

needles, bandages, or other contaminated with blood or other bodily fluids that can transmit disease

Types of Biohazard Waste:Human blood and blood products

serum, plasma, etc

Types of Biohazard Waste:Pathological Waste

all human tissues, organs, and body parts

Types of Biohazard Waste: Microbiological Wastes

contaminated with concentrated forms of infectious agents

More types of biohazard waste is…

animal waste and recombinant DNA & RNA

Sharps

are medical equipment that can cut or puncture the skin, needles, syringes, and razors.

Not sharp waste

gloves, paper towels, lab glass, and petri dishes.

Autoclave Sterilization

special chemicals to the sharps in order to kill the microorganisms that may cause disease.

Personal Protection Equipment(PPE)

is equipment worn to minimize exposure to hazards that cause serious workplace injuries and illnesses(ex.gloves, earplugs, full body suit, etc)

Donning(Putting on)

-Identify and gather the proper PPE to don.

-Perform hand hygiene using hand sanitizer.

-Put on isolation gown

-Put on face shield or goggles

-Put on gloves and then healthcare personnel enter patient room.

Doffing(taking off)

-Remove gloves,-remove gown,-exit patient room,-perform hand hygiene,-remove face shield, remove and discard respirator,-facemask, perform hand hygiene after removing respirator

ACC

American college of radiology

AHA

American Heart Association

Level of Evidence(LOE)

estimates the certainty of treatment effect on patients and is classified as level A,B, or C.

COR l

is a strong recommendation that indicating established usefulness and effectiveness

COR lla

is moderate recommendation where benefit likely outweighs risk.

COR llb

is a weak recommendation where benefit is less certain.

COR lll

is an action not recommended due to lack of benefit or potential harm.

Atrial fibrillation

is the absence of P waves and irregular fibrillatory waves between the QRS complexes

V-tach(Ventricular Tachycardia)

 is made when there is a disruption in the hearts normal electrical signaling within the lower chambers(ventricles). This causes the heart to beat too fast.)

Ventricular fibrillation

is a dangerous heart rhythm where the lower chambers of the heart shake instead of pumping blood effectively

2 degree block(second degree atrioventricular(AV) block

 is a condition where some electrical impulses from the atria fail to reach the ventricles, causing skipped heartbeats. 

3-degree blocks(complete heart block)

is a severe condition where the electrical signals from the atria fail to reach the ventricles. This can lead to a slow heart rate and insufficient blood flow.
