Well, we've covered a lot of important definition material
and you may need to repeat this lecture a couple of times to make sure you have all of the numbers down
or you may have taken notes on that so you remember.
00:13
Once you start reading ECGs, it'll become easy to remember what the various intervals should be.
00:19
Oh, the PR needs to be less than 5 little boxes, and so forth. Let's do a case.
00:24
Okay. Here's a 22-year-old male student who's the captain of the university boxing team
and he comes in to you because he's having anterior, that is chest -- pain in the front of his chest.
00:35
The discomfort occurs several times each day and lasts for 1 to 2 hours.
00:40
On physical exam, he's very tender when you touch the sternum
and he did admit that during a number of boxing matches recently,
he took a number of hits on the sternum.
00:50
By the way, what are the important points here? Number one, chest pain.
00:54
That's why he was referred. Number two, there's a history of some thoracic trauma and here is the ECG.
01:00
So, it's a normal ECG. It's the one I showed you before.
01:05
So that's very reassuring because what we were worried about -
well, we worried that maybe you know, he'd gotten some injury to the blood vessels in the heart
and maybe he had a heart attack during one of these episodes.
01:18
So, the patient's chest pain is musculoskeletal in origin.
01:22
It's the result of the trauma that he suffered when he was boxing
and you can reassure the patient it'll get better with time.
01:29
Treatment: you can give some non-steroidal, anti-inflammatory agent such as Naprosyn
and reassurance and no further testing is required.
