Name: Score:60 Multiple choice questions
Definition 1 of 60
- Ventricles relax and fill with blood -lower pressure in ventricles than in atrium = AV valves open;
blood from atrium to ventricles
- increase in HR, decreases ventricular filling & atrial contraction marks the end - diastole
Indicates myocardial ischemia
Myocardial Ischemia
Significance of the QRS axis
1st phase in cardiac cycle
Term 2 of 60
SA block
This is the inability of an electrical impulse to be generated by the SA node causing no P
wave to be seen. May occur intermittently and cause the pt no problem or symptoms.
-Upsloping ST that does not return to baseline in 80 milliseconds beyond the J-point:
________ severe
-Downsloping ST: _________ severe & 99% dependable for predicting CAD
- abnormality in the electrical conduction system of the heart that disrupts the propagation
of electrical impulses through the AV node.
- a decreased spread of electrical impulses leads to a decreased HR
- Symptoms: fainting, dizziness, SOB, CP
-Changes in the J-point & ST segment
-Mets < 6.5
-Duration < 6 minutes
-Low peak HR
-Maintaining a low systolic BP
-Severe ST depression
-Prolonged ST depression
,Definition 3 of 60
- 3 standard leads
- one positive and one negative electrode
- measures the difference in electrical potential recorded by each electrode
- views the heart's activity in a frontal plane
- Einthoven's law describes placement & math relationship to each other
Bipolar ECG leads
Myocardial Ischemia
ST segments on ECG
Atrial Hypertrophy
Term 4 of 60
v3 & v4
Precordial
- placed at the 5th intercostal space on the
midclavicular line
& -this lead lies in between V2 and V4
Precordial
- placed over the left ventricle at the 5th intercostal space at the anterior axillary line and
the midaxillary line
(Precordial)
- leads placed over right ventricle at the 4th intercoastal space on the right and left sides
of the sternum
(Bipolar)
- placed on RT arm (-)
- placed on LT leg (+)
,Definition 5 of 60
-used for pts with orthopedic, vascular, or neurological limitations
-need the ability to be adjusted manually or electronically
Precordial Leads
QRS wave complex
Bicycle Erogmeter
Bipolar ECG leads
Definition 6 of 60
- negative wave on ECG
- normal duration is small but actual value will depend on which lead is used to measure the wave
in ECG
- often less than 0.03
- enlarged suggests abnormal conduction in the ventricles or a myocardial infarction
QT interval
ECG voltage
Q wave
P wave
, Definition 7 of 60
(Bipolar)
- placed on RT arm (-)
- placed on LT leg (+)
Lead II
Treadmill
aVR
v3 & v4
Definition 8 of 60
Lead that detects myocardial ischemia
V5 & V6
aVR
V5
Class "C" fire extinguisher
or
Baking Soda
Term 9 of 60
Failure of a cardiac PM on ECG
- QRS is absent & p wave may/may not be absent
- small pacer spikes may still be seen
-a measure of exercise intensity based on oxygen consumption
-1 is = the amount of o2 a person consumes per unit of body weight during 1 min of rest
- elevated ST segment
- may be seen in any lead
- positive wave
- may or may not be preceded by a Q wave
- represents ventricular depolarization
