Welcome to the Med Max Channel!
Today we continue our cardiology series with Part 6: Supraventricular Dysrhythmias, one of the most important topics for clinical practice and NCLEX preparation.


This lesson is packed with ECG illustrations, showing exactly how each rhythm appears in real life.
I spent significantly more time preparing this video than previous ones because I wanted to ensure that every dysrhythmia is demonstrated visually:
0:00 Introduction in to Supraventricular Rhythms
3:30 Sinus Node Rhythms - Sinus bradycardia
4:20 Sinus Tachycardia
5:00 Sinus Arrhythmia
5:35 Sick Sinus Syndrome
6:20 Atrial Dysrhythmias - PACs (Premature Atrial Contractions)
7:10 Atrial Tachycardia
8:00 Atrial Flutter
8:45 Atrial Fibrillation
9:45 AV node reentry mechanisms - PSVT (Paroxysmal Supraventricular Tachycardia)
10:55 AVNRT(Atrioventricular Nodal Reentrant Tachycardia)
11:45 Accessory pathway tachycardias - WPW (Wolff–Parkinson–White Syndrome)
12:50 Overall and Red Flags
13:50 Challenging NCLEX-style question

In this episode we break down:
• Sinus node rhythms (bradycardia, tachycardia, sinus arrhythmia, sick sinus syndrome)
• Atrial dysrhythmias (PACs, atrial tachycardia, atrial flutter, atrial fibrillation)
• AV node reentry mechanisms (PSVT, AVNRT)
• Accessory pathway tachycardias (AVRT / Wolff-Parkinson-White)
• How to interpret narrow-complex rhythms on ECG
• Clinical red flags and when cardioversion is required
• Key NCLEX principles: stroke risk, anticoagulation, adenosine, and rhythm recognition

If this video reaches 10 likes, I will upload a complete PDF guide with all the structured notes from this lesson — perfect for your NCLEX notebook.

At the end of the video, I also include a very challenging NCLEX question.
The correct answer will be revealed in the next episode.

Thank you for watching, and welcome to a place where complex medical topics become clear and visual.
