Q

What is the distance from the beginning of the P wave to the Q called? What is it measuring?

A

PR interval, R is referring to the R wave. it is a time interval, if the PR interval takes too long you have a conduction problem from the SA to the AV node

Q

What is the ST segment?What does it represent?

A

the end of R wave to the T wave, it represents repolarization of the ventricles

Q

How long is the PR interval?What if it takes longer?

A

0.12 to 0.20 secondsIf it is longer there is a problem with conduction between the atria and the ventricle

Q

What is the time measurement of the itty bitty boxes?

A

0.04 seconds

17
Q

What is the time measurement of the larger boxes?

A

0.20 seconds

18
Q

How many seconds are the test strips measured in?

A

6 seconds

19
Q

How do you remember where to put the tele leads?

A

‘Snow’ on the grass (R), smoke over fire (L) & chocolate next to my heartwhite on the right

20
Q

What is the difference between tele and an ecg?

A

Continuous Unidimensional ViewMonitoring Only vs. Snapshot in TimeRoutine or STAT Multidimensional View (12)Diagnostic

21
Q

What do we need to know about reading a 12 lead ecg?

A

If there are two contiguous leads - next to each other on the monitor strip with elevated ST elevations, that can dx a STEMI

22
Q

What is artifact?

A

irregularity in the ECG lead that is not coming from the patient
