Blood pressure |
Force exerted by circulating blood volume on the walls of the artery during circulation |
|
Diastole |
Period of relaxation & filling of all cardiac chambers |
|
EKG running speed |
25mm per second |
|
Heart Skeleton |
Made up of 4 rings of thick connective tissue |
|
Left ventricle |
Receives oxygenated blood from left atrium and pumps it to the body thru the aorta |
|
P Wave |
Atrial depolarization |
|
Pulmonary arteries |
Carries deoxygenated blood AWAY from body |
|
Pulmonary veins |
Carry oxygenated blood TOWARDS body |
|
Systole |
Period of contraction of the heart |
|
ST segment |
Time of ventricular contraction and beginning of repolarization of both ventricles |
|
PR interval |
P Wave & PR segment |
|
PR segment |
Measured from end of P Wave & beginning of QRS complex. Goes to AV Node, purkinje fibers, & repolarization of atria |
|
Right Ventricle |
Receives deoxygenated blood from right atrium which pumps to the lungs for oxygenation |
|
Right atrium |
Receives deoxygenated blood returning to the heart from body via superior vena cava. Largest vein in body |
|
S Wave |
1st negative produced by ventricular depolarization. Follows 1st positive deflection(r wave) |
|
ST segment |
Time of ventricular contraction & beginning of repolarization of both ventricles |
|
QRS complex |
Represents ventricular depolarization |

Chilled in crushed ice and water mixture |
|
Acts as a pacemaker when highe level pacemakers fail |
Purkinje Fibers |
|
Analytical errors after blood collection |
Glycolisis(failure to separate serun from cell), not inverting tubes, improper storage conditions, dimming clots |
|
Analytical errors during blood collection |
Extended tourniquet time, hemolysis, wrong order of draw, failure to invert, faulty technique undet filling tubes |
