Q

Atrial Flutter

A

Single automaticity foci fires on top of SA node, resulting in at least 2 P waves // QRS is typically normal and regular R to R // 2:1 ratio example

Q

Premature Ventricular Contraction (PVC)

A

Premature QRS
Wide QRS (-0.12s)
Big amplitude
Usually opposite polarity

17
Q

With a single PVC the heart will pump ___ % of normal SV. With a second PVC the heart will pump ___ %

18
Q

Ventricular Bigeminy
Ventricular Trigeminy
Ventricular Quadrigeminy

A

1 normal beat followed by 1 PVC
2 normal followed by 1 PVC
3 normal followed by 1 PVC

Must occur at least twice for all above

19
Q

Unifocal PVC
Multifocal PVC

A

Unifocal = originating from the same foci so PVCs will all look the same
Multifocal = originating from diff foci so PVCs will look different

20
Q

PVC couplet vs bigeminy?

A

PVC couplet is 2 PVCs directly in a row whereas a bigeminy has a normal beat separating them

21
Q

Ventricular Tachycardia? (Compared to PVC couplet)

A

Run of 3 or more PVCs back to back compared to a couplet which is 2 back to back

23
Q

Vtach that lasts longer than ___ seconds is known as _____ vtach

A

30 seconds // sustained

24
Q

What does MVP stand for? (Associated with PVC)

A

Mitral Valve Prolapse

25
Mitral Valve Prolapse also known as ___ Syndrome
Barlow
26
R on T phenomenon:
PVC falls on T wave
27
Paroxysmal Tachycardia rate V flutter rate V fib rate
150-250 250-350 350-450
28
Supraventricular Tachycardia
Above ventricles QRS normal May or may not be P wave (examples are a fib or a flutter)
29
True or false paroxysmal supra vtach is normal
True
30
Carotid massage is sometimes used to
Slow heart rate
31
Torsades de Pointes
Ventricular Rythm 250-350 Long QT segment “Twisting of points” the amplitude is big then small then big then small
32
Ventricular flutter
Rate 250-350 Smooth sin wave Similar to torsades but amplitude will not change
33
Ventricular Fibrillation
Follows ventricular flutter Dying heart No identifiable QRS “Bag of worms”
