Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

10 notecards = 3 pages (4 cards per page)

The Cardiovascular System: Intrinsic Conduction System

front 1

The intrinsic conduction system consists of ___________________ calls that initiate and distribute ______________ throughout the heart.

back 1

1. Autorhythmic cardiac
2. Impulses

front 2

The intrinsic conduction system coordinates heart activity by determining the direction and speed of ______________. This leads to a coordinated heart contraction.

back 2

Heart depolarization

front 3

List the functions fo rthe following parts of the intrinsic cnduction system:
a. SA Node_______________________________
b. Internodal Pathway________________________
c. AV Node_______________________________
d. AV bundle (Bundle of His)__________________
e. Bundle Branches__________________________
f. Purkinje Fibers___________________________

back 3

a. Sets pace for whole heart
b. inks between the SA and AV nodes
c. Delays occur here, while the atria of the heart contract.
d. Links between atria and ventricle
e. Conveys impulses throughout the ventricular walls

front 4

The action potentials spread from the autorhythmic cells of the intrinsic conduction system (electrical event) to the ______________ cells. The resulting mechanical events cause a heartbeat.

back 4

Contactile

front 5

A tracing of the electrical activity of the heart is called a/an ____________________________.

back 5

ECG (Electrocardiography)

front 6

What do the following wave forms reflect?
a. P wave________________________
b. QRS complex______________________
c. T wave________________________

back 6

a. Atrial depolarization
b. Ventricular depolarization
c. Ventricular repolarization

front 7

In a normal ECG wave tracing, atrial repolarization is hidden by ___________________.

back 7

QRS interval

front 8

Note: Electrical events lead to mechanical events. Foe example, the P wave represents ___________ depolarization, which leads to atrial ____________.

back 8

1. Atrial
2. Contraction

front 9

A left bundle branch block would have a wider than normal wave for the _______________.

back 9

QRS interval

front 10

An abnormally fast heart rate (over 100 beats per minute) is called: _________________.

back 10

Tachycardia
