Q

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

A

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.

Q

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

A

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.

Q

QRS Complex wave is which chamber (atria or ventricles)

A

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

17
Q

P Wave is which chamber (atria or ventricles)

A

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

18
Q

T wave is which chamber (atria or ventricles)

A

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

19
Q

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

A

False

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

20
Q

What sends oxygenated blood to the body?

A

The Left ventricle sends oxygenated blood to the body

21
Q

Where does the electrical stimulus begin in a normal heartbeat?

A

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

22
Q

What is the main contributor to the coronary disease?

A

Atherosclerosis

23
Q

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

A

False

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

24
Q

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

A

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)

25
Q

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

A

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

26
Q

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

A

Dilated Cardiomyopathy

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

27
Q

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

A

Restrictive cardiomyopathy

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

28
Q

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

A

Hypertrophic cardiomyopathy

29
Q

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

A

True

It pumps oxygenated blood to the body

30
Q

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

A

True

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

31
Q

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

A

True

32
Q

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

A

Interventional cardiologist

33
Q

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

A

Angioplasty & Stent placement

CABG and ICD placement are NOT part of PCI

34
Q

What does ventricular fibrillation look like?

A

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

35
Q

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

A

True

36
Q

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

A

True

37
Q

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

A

True

38
Q

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.

A

38%

39
Q

How many patients were enrolled in the BMAD Trial?

A

522 patients

40
Q

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

A

Radar wave/ radio frequency measurements

41
Q

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

A

True

42
Q

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

A

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.
