WHAT'D YOU CALL ME
also known as the receiving chambers
right & left atria
diastole or repolarization =
relaxation
the difference between agonal and asystole on an EKG is
the heart rate
asystole is 0, agonal is less than 20
these letters represent a complete cardiac cycle
PQRST
the heart chambers empty blood during this phase
contraction
systole
depolarization
the beginning of one beat to the beginning of the next beat is also called the
cardiac cycle
2 other terms for cardiac relaxation are
diastole
repolarization
the standard checks the EKG ______
voltage
T wave shows
relaxation of the heart
(repolarization/diastole of the ventricles)
2 purposes of the conduction system
initiate the heart beat
regulate the cardiac cycle
systole or contraction =
depolarization
2 other terms for cardiac contraction are
systole
depolarizatin
the limb electrode that shows no cardiac info and serves as a ground electrode
right leg
a U wave can show up here
after the T wave
this is the purpose of the SA node
generates the stimulus to make the heart beat
repolarization or relaxation =
diastole
leads AVL, AVR, AVF can also be called
augmented leads
a muscle tremor on the EKG looks like this
a fuzzy, irregular baseline
a U wave can appear when the patient has very low
the AV bundle is located where
on the wall between the right atrium & the right ventricle
diastole or repolarization =
relaxation
precordial leads can also be called these 2 names
chest leads
V1-V6
these can commonly cause an interrupted baseline
dirty electrodes
the QRS complex occurs when
the ventricles contract
(ventricular systole/depolarization)
list the order of electrical conduction in the heart
