Alright. Here we go. Arrhythmias. Take a deep
breath. The topic that is hot, the topic that
can be complicated, but we will organise our
thoughts as much as possible. And if there
are certain aspects of this that you feel
are overwhelming, take a deep breath and just
dissect each part of this. Remember you need
to know just enough where you walk into your
rotation, your first year of residency or any
licensing exam and you know arrhythmias well
enough where you can pretty much spar with
any audience. So let us begin and make you
feel comfortable with the concept of arrhythmias.
Now, with arrhythmias, we will first and foremost
in terms of organisation, we will talk about
dysrhythmias. Now as soon as we say arrhythmia,
do not think that it is always sped up. It
doesn’t always have to be tachy and it doesn't
always have to be brady. It could either or.
So, for example obviously, we will get into
our AV node blocks. And we will talk about
other types of tachyarrhythmias. Conduction
system disease is what we are looking for.
For example, last time we even introduced
any type of arrhythmia with post MI. Post
myocardial infarction, one of the most common
causes of death or sudden death is arrhythmia.
Why? The repair process in which now the wall
of your heart has become disrupted is only
going to disrupt the conduction system, isn't
it? And so, therefore, we will then lead into
some type of arrhythmia. And on the other
side, we will take a look at some of those vascular
diseases. The same thing. Anything that causes the disruption
of the conduction system, either inheritently
or secondary by disruption of your blood flow,
is going to result in an arrhythmia, extremely
common. Hypertrophic obstructive cardiomyopathy,
do you think the patient might have an arrhythmia?
Sure. It is with the intraventricular septum
and if you are going to have hypertrophy,
could you then disrupt the condution system?
Sure you can. So are you seeing this now?
Okay. So I don't want you to have resistance against
arrhythmia. In fact, I want you to welcome it
because this is just a wonderful topic in which
we can integrate a lot of topics.
Now, with dysrhythmia, a conduction system.
