Understanding Different Types of Arrhythmias: ECG Interpretation (Part 3)

📚 This video is the third lesson in a series on ECG/EKG rhythm interpretation, focusing on different types of arrhythmias.

🔍 The video covers sinus arrhythmias, premature beats, bradycardic and tachycardic rhythms, atrial dysfunctions, junctional rhythms, ventricular problems, and heart blocks.

💡 The presenter aims to help viewers identify and understand the causes and key characteristics of each type of arrhythmia.

📚 This video discusses different types of arrhythmias and how to identify them using EKG interpretation.

🔍 The first type of arrhythmia discussed is sinus arrhythmia, which originates in the SA node. It is characterized by an irregular heart rate with increasing and decreasing beats.

⏱️ Using the six-second method, the heart rate of a sinus arrhythmia can be estimated to be 60 beats per minute.

📚 Different types of arrhythmias exist, but we will focus on basic arrhythmias in this lesson.

⚡️ There are three types of premature beats: premature atrial complexes (PACs), originating from the SA node; premature ventricular complexes (PVCs), originating from the ventricles; and premature junctional complexes (PJCs), originating from the AV junction.

❗️ To identify a PAC, look for narrow QRS complexes, upright P waves, and a possibly different morphology of the P wave compared to other beats.

⭐ Premature Atrial Complexes (PACs) can be identified by their different morphology and are caused by irritations in the atria.

🔀 Premature Junctional Complexes (PJCs) have narrow QRS complexes and inverted or flat P waves, indicating irritation in the AV Junction.

💥 Premature Ventricular Complexes (PVCs) are the most common and can be recognized by their wide QRS complexes and absence of P waves.

⚡️ Premature ventricular complex is identified by a wide QRS complex and the absence of a P wave.

🔋 Sinus bradycardia is characterized by a heart rate less than 60 beats per minute, caused by factors such as athletic conditioning, nervous system dysfunction, or medication.

💗 Sinus tachycardia occurs when the heart rate exceeds 100 beats per minute, and can be a normal response to factors such as stress or physical activity.

📈 Sinus tachycardia is characterized by a heart rate greater than 100, usually caused by increased sympathetic response.

⚡️ Supraventricular tachycardia (SVT) has a heart rate greater than 150, with an indistinguishable P wave and narrow QRS complex.

🔊 SVT can have extremely high rates, sometimes reaching 300.

⚡️ Super ventricular tachycardia (SVT) is a rapid heart rhythm that originates above the ventricles.

🔀 SVT has a pretty regular rhythm with some fluctuations in speed, and it is often caused by increased sympathetic response.

💓 In the next lesson, the different types of atrial, junctional, and ventricular rhythms will be discussed.
