What's going on guys and welcome to episode 13 of the Physician

assistant boards dot-com podcast and today I want to do things a little bit

differently we're going to talk about high-yield e-g and high-yield murmur's.

So this is going to be just quick tidbits

to go over each section.

Only going to go over high-yield information.

Okay, so let's get started. So first thing we're going to go over high-yield information. Okay, so let's get started.

So first thing we're going to talk about is first-degree block.

This is characterized by a long PR interval over 0.20,

and to be honest, you don't treat this.

Second degree block.

This is further divided into two entities.

This can be either Mobits 1 or Wankibok.

Now you're going to notice a PR progressively lengthening until it's going to fail to

produce a P wave and a QRS complex. So you're going to see a continuously

progressing PR interval and then a dropped complex.

The same pattern will continue repeating with the lengthening of the PR and a dropped B.

If they're asymptomatic, you do not treat. If they have symptoms like signs of hypo-perfusion give a pacemaker.

Mobits 2, the patient will continuously have a dropped QRS complex, like in Mob it's one, but there's no lengthening of the PR.

So you're going to have a normal PR throughout, and then all of a sudden you're going to have a dropped complex.

Now a patient can present with syncope and you're going to treat everybody with the Mobitz 2 with a pacemaker

because this can progress to a complete block.
