CVPR Week 2: Heart model and ECG Part I Flashcards
1
Q
Identify
A
2
Q
The P wave coincides with?
A
3
Q
QRS Complex coincides with?
A
4
Q
The T wave coincides with?
A
5
Q
How to identify rate on ECG
A
- look at the rhythm strip
- 1 big box = 0.2 seconds
- 1 little box = 0.04 seconds
6
Q
Big box method
A
7
Q
Find the rate
A
79 bpm
8
Q
How to identify the rhythm
A
- look for a P wave in front of QRS complex
- look for equidistance between different waveforms such as R waves
9
Q
Rhythm
A
equidistance between R waves and preceded by P wave
10
Q
Identify Rate and Rhythm
A
11
Q
ECG Intervals
A
12
Q
Axis in ECG
A
really talking about the axis of the ventricles
13
Q
How to place leads for ECG
A
14
Q
Direction of leads
A
right to left
15
Q
Lead 1
A
right arm to left arm
16
Q
What is this about?
A
17
Q
Leads through the heart
A
18
Q
Augmented leads
3 listed
A
- AVF
- AVR
- AVL
19
Q
AVF Lead location
A
20
Q
is the axis normal on an ECG
A
- because the AVF has an upward R that means there is a downward component
- upright lead in AVR lead 1 means leftward
so the axis is normal
21
Q
What can we tell about this ECG?
A
22
Q
leads locations in the heart
A
23
Q
How do cardiologists think about heart leads?
A
24
Q
If the depolarization was straight down?
A
25
If the AVF is biphasic?
26
find the lead that gives the least information
AVL travels
27
Normal and abnormal axis
