Back 10

diastole

Front 11

Back 11

systole

Front 12

wave produced when the atria depolarize

the first wave (ECG)

Back 12

P-wave

Front 13

first negative ventricular deflection

Back 13

Q-wave

Front 14

first positive ventricular deflection

Back 14

R-wave

Front 15

first negative deflection after the R-wave

Back 15

S-wave

Front 16

if there is no positive R-wave, the negative deflection is called the _-_ wave

Back 16

Q-S wave

Front 17

this wave marks the change in voltage created by ventricular repolarization

Back 17

T-wave

Front 18

the _-_ segment corresponds to the time when calcium has entered the cardiac myocytes

ventricles are contracting

Back 18

S-T segment

Front 19

Describe what is happening at each of these points:
P
Q
R
S
T
ST segment

Back 19

P: atria depolarize
Q: first negative ventricular deflection
R: first positive deflections from the ventricle
S: first negative deflection after the R-Wave
T: the change in voltage
ST: corresponds to the time when calcium has entered the cardiac myocytes and the ventricles are contracting
