Putting it all together
Finish line dead ahead!
Approaching ECG interpretation from the perspective of "sensitive, not specific" is completely fine.
a) It is sufficient for "advanced" life support.
b) if you can detect a problem, you can then ask someone with more experience to be more specific about what it is you've seen.
By this stage, you will be able to answer the following:
-
Is the rhythm compatible with a pulse?
-
What is the axis?
-
What is the heart rate?
-
Is it regular, or irregular?
-
Is the QRS complex narrow, or wide?
-
Are there P waves?
-
Is the PR interval normal?
-
Are the P waves interacting with the Q waves normally?
-
Are the Q waves behaving?
-
Is the R wave progressional normal?
-
Is the ST segment at baseline?
-
Are the T waves normal?
-
Is the QT normal?
If not, click on the relevant section for a reminer!
And that is honestly more than sufficient.
(Unless you're the med reg.)
And that's it!

Examples to consolidate learning:
Example 1:

-
The rhythm is compatible with a pulse.
-
It has a normal axis.
-
The HR is around (300/3.5) = ~85
-
It is regular.
-
The QRS is narrow.
-
There are P waves.
-
The PR interval is normal.
-
The P waves and Q waves are in a 1:1 ratio and interacting normally.
-
There are no anterior Q wave problems, but the inferior ones look suspicious.
-
There is normal R wave progression.
-
The inferior lead ST segment seems to be off baseline.
-
There are no major T wave problems.
-
The QT is normal.
