Part 6: The P wave
Every story has a beginning.
Some stories, like game of thrones, may have been better off without an end.
Nevertheless, the beginning of our story will actually start at the end.
That is to say, that the paradigm of "PQRST(U)" +/- Delta, Epsilon, Osborn exist within the context of normality.
The first step in interpreting the variant components of an ECG are to understand the following rhythms:
That is because these rhythms are generally considered bad for your immediate health, and you have a high probability of not having a pulse.
Therefore, instead of nerding out over what the ECG shows, you require immediate action.
Like summoning the medical registrar.
On the other hand, if you understand the above rhythms, congratulations - you're pretty much ready to tackle the cardiology section of ALS.
The author will at this point state that the "Advanced" in "ALS" is both subjective and relative to what else exists, and is not an objective measurement.
The author is fairly certain that readers will probably understand that anything without an objective definition will be difficult to quantify, as he has seen "ALS" stand for "Anxiety Level: Severe" as well as "All Logic Suspended" in equal measure.
Back to our original subject matter:
