Q

what is common when the sinus rate is very slow?

A

Etopic beats from av node and ventricles may fire to maintain cardiac output.

Q

What is the treat meant for brady?

A
  1. Focus on patient tolerence and look for the cause.
  2. If symptomatic the consider atropine, then pacing to increase ventricular rate.

Q

Atrial fibrilation p waves

21
Q

Atrial fibrilation rhythem is

Study These Flashcards
A

irregularly irregular

22
Q

Atrial fibrilation rate

23
Q

Atrial fibrilation key to identifying

Study These Flashcards
A

is it is highly irregularly irregular

24
Q

Super ventricular tachycardia P wave is

Study These Flashcards
A

unable to be seen

25
Super ventricular tachycardia R to R is
regular
26
Super ventricular tachycardia qrs is
. 4- .12 ms
27
Super ventricular tachycardia rate is
150-180 bpm
28
Super ventricular tachycardia has a tendency to ....
Come and go and therfore gets its name Paroximal svt ( meaning in spasms) aka re-entry svt
29
Super ventricular tachycardia how urgent is svt
it should be treated promptly because ventricles cant refill reducing cardiac output
30
Premature atrial complex is a
complex within another rhythm.
31
Premature atrial complex occurs when
earlier in time than the next expected complex
32
Premature atrial complex makes the rhythm what..
Irregular
33
Premature atrial complex will have a p wave that is
different from other in morphology
34
wtih Premature atrial complex , the p wave is not always
conducted to the ventricles.
35
What is a non conducted p wave
P wave conducted early and not followed by a qrs.
36
How to differentiate heart blocks from a pac
1. Pac's occure infrequetly and in no pattern 2. Heart blocks pp intervals are constant
37
Premature atrial complex causes
1. cafine 2. heart dissease
38
Wandering atrial pace maker moves from sa node to
various locations of the heart
39
Wandering atrial pace maker rate is
60 -100bpm
40
Wandering atrial pace maker rhythem is
slightly irregular
41
Wandering atrial pace maker p wave is
upright but various morphology
42
Wandering atrial pace maker- what is required to call it that officaly
At least 3 different morphology
43
Wandering atrial pace maker is common in patients with
Lung disiease
44
Wandering atrial pace maker treatment is ...
usually not indicated
45
Multifocal atrial tachycardia has a rate of
more than 100 bpm
46
Multifocal atrial tachycardia rhythm is
regular irregular
47
Multifocal atrial tachycardia R to R....
varies depending on site of pace maker
48
with Multifocal atrial tachycardia, if rate exeeds 150 bpm the p waves ....
may not be visible , thus the only indication may be the irregularity associated with the varying sites of origin
49
Multifocal atrial tachycardia treatment ....
Not attempted in field. svt treatment not affective with Multifocal atrial tachycardia
