A

Cardiac Output

(PER MINUTE)

18
Q

What is the formula for Cardiac Output?

A

Heart Rate x Stroke Volume = Cardiac Output

19
Q

Which side of the heart has deoxygenated blood?

A

Right side

goes to the lungs

20
Q

Oxygenated blood sent to the rest of the body is from what side of the heart?

A

Left side

21
Q

What is the function of the heart valves?

A

Prevent backflow of blood

22
Q

Which electrolytes crucially affect cardiac function?

A

Sodium
Potassium
Calcium

23
Q

The ability of a cell to generate its own electrical impulse is…

A

Automaticity

24
Q

What leads are you looking at for Bundle Branch Blocks?

A

V1 and V6

  • Deep, Wide S Wave
  • Everything looks Wide
  • 2 R Waves
25
Q

What is unique about the appearance of a Right Bundle Block?

A

They appear like Bunny Ears

26
Q

If there is no P Wave with bizarre wide complexes, where do you think it’s firing from?

A

Ventricles

27
Q

What is the difference between Unifocal and Multifocal?

A

Unifocal – arising from a single ectopic focus; each PAC is identical.

Multifocal – arising from two or more ectopic foci; multiple P-wave morphologies.

28
Q

If the ST elevations appear tombstone like, what does that mean?

A

Heart attack - infarction

Patient will be symptomatic

A

60-100 bpm

31
Q

The AV Node fires at what rate?

A

40-60 bpm

31
Q

32
Q

The QRS complex at it’s normal range is how long?

A

2-3 small boxes
(0.08-0.12 sec)

33
Q

What rhythm is most likely to have 3 different P Waves; upright, inverted or absent

A

Wandering Atrial Pacemaker
(WAP)

34
Q

What does Atrial Flutter look like?
