EKG
these are plates that come between the current and the patient
electrodes
the term electrocardiograph is
the instrument used for recording the heart's activity
this wave shows atrial contraction
P
when do you standardize an EKG
before & after EKG
if the heart beat fires ECTOPICALLY it means that the firing of the stimulus to generate the heart beat doe NOT occur in the
SA node
augmented lead AVR goes to the
right arm
each large square measures
5mm X 5mm
when the myocardium is stimulated, it will
contract
the speed that the EKG is normally run
25mm/sec
if the ventricles are in systole phase they are pumping the blood out of the heart by
contraction
lead AVF goes to the
left leg
each small square is
.04 sec
1mm X 1mm
the myocardium is made up of
muscle
color of ekg ground lead

an artificial pacemaker produces what on an EKG
a straight, hard vertical line
the cardiac muscle is unique because
it's all fused together and acts as one
this is the EKG machine
electrocardiograph
the left ventricle is the largest because
it has the job of pumping blood to all parts of the body
another name for the resting phase on the EKG
baseline
polarization
calculate the heart rate on a 6 second strip by
counting the R & multiplying by 10
sinus arrhythmia can be caused by changes in
breathing
this is the actual EKG printout
electrocardiogram
the blood in the pulmonary veins gpes to
the left atrium
