ATM Quiz Questions Flashcards
True or False - “the LifeVest consists of 4-sensing electrodes and 3-therapy electrodes
True
the default heart rate settings for the LifeVest are?
150 VT, 200 VF
True or False - “ventricular fibrillation (VF) is a lethal arrhythmia. Death will occur if not treated immediately.”
True
True or False - “Sustained VT is defined as VT of less than 20 seconds in duration.”
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.”
True
“The LifeVest treats Ventricular Tachycardia (VT) and ?”
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?”
True
True or False - “The LifeVest garment can fit patients with a chest circumference of 26-56 inches.”
True
The LifeVest treats Ventricular Fibrillation (VF) with in how much seconds? What about Ventricular Tachycardia (VT)
VF - 25 seconds
VT - 60 seconds
what does ventricular tachycardia look like
potentially fatal heart rhythm
very rapid abnormal rhythm
dizzy and can lose consciousness
what does supra ventricular tachycardia look like
What does atrial fibrillation look like
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?
Lungs/Body
What is the structure in the hart called that generates an electrical impulse to initiate the cardiac conduction cycle and where is it located?
SA Note/Right Atrium
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?
Sinoatrial node (SA node/pacemaker) -
AV node - Bundle of His - left and right ventricles
QRS Complex wave is which chamber (atria or ventricles)
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
P Wave is which chamber (atria or ventricles)
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
T wave is which chamber (atria or ventricles)
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
True or False - Venus carry blood away from the heart, while arteries carry blood towards the heart
False
Arteries carry blood away from the heart, while veins carry blood towards the heart
What sends oxygenated blood to the body?
The Left ventricle sends oxygenated blood to the body
Where does the electrical stimulus begin in a normal heartbeat?
the electrical stimulus begins in the Sinoatrial (SA) node, which is located in the right atrium of the heart
What is the main contributor to the coronary disease?
Atherosclerosis
True or False - like hair and skin cells, hart muscle cells can be replaced after they are lost
False
heart muscles have very limited ability to regenerate after they are lost
True or False - Troponins are proteins that are only found in heart muscle cells and are used to help diagnose a myocardial infarction
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)
On an ECG, what would indicate a full thickness death of the heart muscle?
ST elevation myocardial infarction (STEMI) indicates a full thickness death of the heart muscle on an ECG
Which type of cardiomyopathy is caused by the stretching and thinning of the heart muscle wall resulting in reduced cardiac output?
Dilated Cardiomyopathy
it is caused by the stretching and thinning of the heart muscle wall, which results in reduced cardiac output
Which type of cardiomyopathy is caused by the stiffening of the hart chamber walls making it harder for the heart to fill with blood?
Restrictive cardiomyopathy
It is caused by the stiffening of the heart chamber walls, making it harder for the heart to fil with blood
Which type of cardiomyopathy is caused by the asymmetric thickening of the heart muscle wall where the septum enlarges and blocks cardiac output?
Hypertrophic cardiomyopathy
True or False - the left side of the heart pumps blood to the body
True
It pumps oxygenated blood to the body
True or false - fluids build up in the lungs is a common symptom of left sided heart failure
True
Fluid buildup in the lungs, known as pulmonary congestion or pulmonary edema, is a common symptom of left-sided heart failure
True or False - Right sided heart failure results in fluid build u in the feet, legs, and abdomen
True
Which type of doctor would a patient typically see to treat myocardial infarction?
Interventional cardiologist
What procedures are associated with Percutaneous Coronary Intervention (PCI)?
Angioplasty & Stent placement
CABG and ICD placement are NOT part of PCI
What does ventricular fibrillation look like?
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
true or false - HFMS is the only ambulatory, non-invasive technology for fluid management following an acute decompensation event
True
true or false - thoracic fluid index (TFI) is a unitless number that represents changes of the patients thoracic fluid baseline
True
true or false - 90% of heart failure hospitalizations are due to symptoms of fluid overload
True
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.
38%
How many patients were enrolled in the BMAD Trial?
522 patients
The HFMS device measures TFI (Thoracic Fluid index) by:
Radar wave/ radio frequency measurements
true or false - watchPAT can detect obstructive sleep apnea (OSA) as well as central sleep apnea (CSA)
True
true or false - the watch PAT utilizes non-airflow PAT signal technology
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.
