Review of the Healthy Heart (Nursing)

00:00 Hi! Welcome to our video series today.

00:03 This is post myocardial infarction or the rebuilding of the wall.

00:08 Now we know that a myocardial infarction is a big deal.

00:11 It's a life-altering event, but I want to share with you what your body can do after that.

00:16 It's pretty cool.

00:18 So here's a healthy heart.

00:19 Whoa, whoa, whoa, don't rush through this hang out here for a few minutes and just take a look at what this drawing can teach you now first of all, you already know where the right atrium is, the right ventricle, the left atrium and the left ventricle.

00:33 Good job.

00:34 Now look you've got blood coming into that right atrium.

00:38 It's going to go through there through the tricuspid valve and then out to the lungs come back from both lungs into the left atrium.

00:46 So you're still with me.

00:47 It's going to go through that valve.

00:49 Remember what that name is? Why am I not telling you? Because this is a gentle reminder to you that it's really important that you learn the placement and the names of each of the valves in the heart.

01:03 So write yourself a quick note if some of those are a little unclear you just need to be refreshed so you can remind yourself of how important it is to know where those valves are.

01:12 Now cool part you can take away right now, is look at how those valves work.

01:16 This is why they're one way notice in systole, which valves are open.

01:21 So systole is when the heart is pumping down, squeezing down notice which valves are open and which valves are closed.

01:29 Now when you see that heart wall, relax again, know which valves are open.

01:34 And now the ones that were open in systole are now closed in diastole.

01:40 So you've got systole and diastole, systole and diastole.

01:46 Now, I encourage you to take a little bit of time to look at this picture without my voice.

01:51 So I want to give you a few seconds just to look at it.

01:54 So I'm going to be quiet and let you take a look.

02:05 All right.

02:05 I promise time invested here is going to benefit and pay off for you in other areas, but you have to admit this is a pretty amazing machine in your heart.

02:17 Now this makes sense why they left anterior descending.

02:21 The Widowmaker is such a huge deal and why it has the highest mortality rate.

02:26 Look how strongthat left ventricular wall has to be to push blood out to the rest of the body.
