Good day:
What comes to mind would be knowing the terms, sequence, etc. for the following:
P wave
QRS complex
T wave
P–Q interval
S–T segment
Q–T interval
I would also recommend looking up the correlation of ECG waves with atrial and ventricular systole. Look up what makes up the cardiac cycle start to finish.
Thank you.
That "mmHg" chart shows what's going on. When you see a bump "up" in pressure, that represents systole, or contraction. The magenta line is atrial pressure. The blue line is ventricular pressure. The EKG shows the electrical side of the contraction stimulus. Notice that the P wave happens just before the atrial pressure bump and the QRS complex happens just before the ventricular big bump. There's a slight delay in stimulation and the response because that's how long it takes the muscle to actually move after it's been stimulated.
The stated "sequence" of events in post #2 is a great place to start and learn the terms. Then all you have to do is match up the terms with what's happening. It's a lot easier than it seems, once you wrap your head around it.

Hoping for some guidance. I'm doing a lab review sheet for A&P2 on the cardiovascular physiology. One question is matching terms to a ECG tracing (that's what the book calls it)
I've looked through my textbook, lab book and online. I can't find anywhere that shows the process relating to the graph. I'm really confused.
I don't want answers just somewhere to find the info so I understand this.
I'm going to add a photo of the graph from the text to clarify.
Thanks in advance.
