ATM Quiz Questions

Question 1

True or False - “the LifeVest consists of 4-sensing electrodes and 3-therapy electrodes

Answer 1

True

Question 2

the default heart rate settings for the LifeVest are?

Answer 2

150 VT, 200 VF

Question 3

True or False - “ventricular fibrillation (VF) is a lethal arrhythmia. Death will occur if not treated immediately.”

Answer 3

True

Question 4

True or False - “Sustained VT is defined as VT of less than 20 seconds in duration.”

Answer 4

False.

Sustained ventricular tachycardia (VT) is defined as VT lasting more than 30 seconds in duration or requiring intervention due to hemodynamic instability within 30 seconds.

VT lasting less than 30 seconds is typically referred to as non-sustained VT.

True or False - “Only the patient should press the response buttons on the LifeVest monitor during a treatment event.”

Answer 5

True

Question 6

“The LifeVest treats Ventricular Tachycardia (VT) and ?”

Answer 6

Ventricular Fibrillation (VF)

These are both life-threatening arrhythmias that the device is designed to detect and treat by delivering a defibrillation shock if necessary.

True or False - “AArD stands for Advanced Arrhythmia Discrimination?”

Answer 7

True

True or False - “The LifeVest garment can fit patients with a chest circumference of 26-56 inches.”

Answer 8

True

Question 9

The LifeVest treats Ventricular Fibrillation (VF) with in how much seconds? What about Ventricular Tachycardia (VT)

Answer 9

VF - 25 seconds
VT - 60 seconds

Question 10

what does ventricular tachycardia look like

Answer 10

potentially fatal heart rhythm

very rapid abnormal rhythm

dizzy and can lose consciousness

Question 11

what does supra ventricular tachycardia look like

Question 12

What does atrial fibrillation look like

Question 13

Where does the blood flow to from the right side of the heart and where does the blood flow to when it leaves the left side of the heart?

Answer 13

Lungs/Body

Question 14

What is the structure in the hart called that generates an electrical impulse to initiate the cardiac conduction cycle and where is it located?

Answer 14

SA Note/Right Atrium

Question 15

After the electrical impulse is generated by the SA node, review its conduction through the heart. What is the order of the path it follows?

Answer 15

Sinoatrial node (SA node/pacemaker) -
AV node - Bundle of His - left and right ventricles

Question 16

QRS Complex wave is which chamber (atria or ventricles)

Answer 16

Ventricle

QRS Complex signifies (terms of cardiac muscle movement) it signifies ventricular depolarization (squeeze or contraction of the ventricles that moves blood simultaneously to the lungs in terms of the right ventricle and to the body from the left ventricle)

Ventricles are more

higher ampullated

Question 17

P Wave is which chamber (atria or ventricles)

Answer 17

Atria

P Wave signifies atrial depolarization - think of depolarization as the deployment or movement of blood from one area to another

The blood from the atria are moved by a simultaneous contraction or squeeze from both atrial chambers, blood then moves from the atria, through the Atrial ventricular valves down to the ventricals

the P wave is positive

Question 18

T wave is which chamber (atria or ventricles)

Answer 18

ventricles

represents Ventricular repolarization - when ventricular walls relax and blood moves in from the atria refilling

rest and refill phase

atrial repolarization occurs when the ventricles are squeezing, depolarizing, and moving deoxygenated blood out to the lungs and oxygenated blood out to the body

the force of ventricular contraction is so powerful that it hides the activity of atrial repolarization on an ECG strip

Question 19

True or False - Venus carry blood away from the heart, while arteries carry blood towards the heart

Answer 19

False

Arteries carry blood away from the heart, while veins carry blood towards the heart

Question 20

What sends oxygenated blood to the body?

Answer 20

The Left ventricle sends oxygenated blood to the body

Question 21

Where does the electrical stimulus begin in a normal heartbeat?

Answer 21

the electrical stimulus begins in the Sinoatrial (SA) node, which is located in the right atrium of the heart

Question 22

What is the main contributor to the coronary disease?

Answer 22

Atherosclerosis

Question 23

True or False - like hair and skin cells, hart muscle cells can be replaced after they are lost

Answer 23

False

heart muscles have very limited ability to regenerate after they are lost

Question 24

True or False - Troponins are proteins that are only found in heart muscle cells and are used to help diagnose a myocardial infarction

Answer 24

True

Troponins are proteins that are primarily found in heart muscle cells and are used as biomarkers to help diagnose a myocardial infarction (heart attack)

Question 25

On an ECG, what would indicate a full thickness death of the heart muscle?

Answer 25

ST elevation myocardial infarction (STEMI) indicates a full thickness death of the heart muscle on an ECG

Question 26

Which type of cardiomyopathy is caused by the stretching and thinning of the heart muscle wall resulting in reduced cardiac output?

Answer 26

Dilated Cardiomyopathy it is caused by the stretching and thinning of the heart muscle wall, which results in reduced cardiac output

Question 27

Which type of cardiomyopathy is caused by the stiffening of the hart chamber walls making it harder for the heart to fill with blood?

Answer 27

Restrictive cardiomyopathy It is caused by the stiffening of the heart chamber walls, making it harder for the heart to fil with blood

Question 28

Which type of cardiomyopathy is caused by the asymmetric thickening of the heart muscle wall where the septum enlarges and blocks cardiac output?

Answer 28

Hypertrophic cardiomyopathy

Question 29

True or False - the left side of the heart pumps blood to the body

Answer 29

True It pumps oxygenated blood to the body

Question 30

True or false - fluids build up in the lungs is a common symptom of left sided heart failure

Answer 30

True Fluid buildup in the lungs, known as pulmonary congestion or pulmonary edema, is a common symptom of left-sided heart failure

Question 31

True or False - Right sided heart failure results in fluid build u in the feet, legs, and abdomen

Answer 31

True

Question 32

Which type of doctor would a patient typically see to treat myocardial infarction?

Answer 32

Interventional cardiologist

Question 33

What procedures are associated with Percutaneous Coronary Intervention (PCI)?

Answer 33

Angioplasty & Stent placement CABG and ICD placement are NOT part of PCI

Question 34

What does ventricular fibrillation look like?

Answer 34

a bunch of squiggly lines this is an extreme abnormal heartbeat Fatal heart rhythm if not treated quickly is fatal if successful defibrillation is not quickly delivered ZOLL LIFEVEST look for abnormal heart rhythms like this one to treatment shock the patient

Question 35

true or false - HFMS is the only ambulatory, non-invasive technology for fluid management following an acute decompensation event

Answer 35

True

Question 36

true or false - thoracic fluid index (TFI) is a unitless number that represents changes of the patients thoracic fluid baseline

Answer 36

True

Question 37

true or false - 90% of heart failure hospitalizations are due to symptoms of fluid overload

Answer 37

True

Question 38

the BMAD Trial demonstrated a what % relative risk reduction in 90-day heart failure hospitalizations with HFAMS TFI data when compared with those in a control arm.

Answer 38

38%

Question 39

How many patients were enrolled in the BMAD Trial?

Answer 39

522 patients

Question 40

The HFMS device measures TFI (Thoracic Fluid index) by:

Answer 40

Radar wave/ radio frequency measurements

Question 41

true or false - watchPAT can detect obstructive sleep apnea (OSA) as well as central sleep apnea (CSA)

Answer 41

True

Question 42

true or false - the watch PAT utilizes non-airflow PAT signal technology

Answer 42

True The WatchPAT device utilizes non-airflow Peripheral Arterial Tone (PAT) signal technology to detect and monitor sleep-related breathing disorders, primarily focusing on obstructive sleep apnea (OSA). This technology measures changes in arterial tone associated with respiratory events during sleep.
