Ecg

Front 1

____________keeps________and __________from binding preventing contraction

Back 1

Troponin, actin, myosin

Front 2

________and _________are heart fibers that use electricity and Ca to contract forming heart beat

Back 2

actin, myosin

Front 3

_______interact with________ and allows myosin to bind with actin

Back 3

calcium, troponin

Front 4

intotropy is__________

Back 4

contraction

Front 5

Calcium increase and is a inotrope

Back 5

contraction, positive

Front 6

Cardiac Cycle:
1. Electrical is:
2. Mechanical is:

Back 6

1. Depolarization/ repolarization
2. systole/diastole

Front 7

1.What happens in Depolariztion?
What happens in Repolarization?

Back 7

1. Sodium enters the cell and potassium leaves the cell, causing a change in cell permability. ACTIVE, contraction
Rest and filling

Front 8

The left and right atria are depolorized through what?

Back 8

1. Buchman's bundle, which causes the atrial kick.

Front 9

1. SA node rate:
2. Av node rate:
3. Perkinje fibers (ventricles) rate:

Back 9

1. 60-100 normal heart pace
2. 40-60 slows it down
3. 15 - 40

Front 10

Atrial depolarization and the firing of the SA node is represented by what on the ECG strip?

Back 10

P wave, and its not to exceed 3 sm boxes.

Front 11

1. Ventricle depolarization is represented by:
2. what is the normal measurment of this:
3. if this become wider (slowed conduction) what is it means?

Back 11

1. QRS,
2. 0.06-0.12

3. either a Bundle Branch Block or ventricle rythym

Front 12

1.What is a normal PR interval?
2. If its longer than normal, it indicate:

Back 12

1. 0.12-0.20
2. first degree av block

Front 13

1. ST elevation > 1mm
2. ST depression > 1mm

Back 13

1. MI
2. digoxin, ischemia

Front 14

1. ventricle repolarization comes after QRS, No more than five boxeds, is represented by:
2. Inversion indicate
3. if its higher than five boxes it indicate

Back 14

1. T wave
2. ischemia
2. Potassium level increase

Front 15

1. four steps for interpretation of rythym are:

Back 15

a. rythmycity (reg vs irreg)
b. rate (atrial and ventricle)
c. wave form configuration and location.
d. intervals
