3 Variations of Complete Heart Block (from better, to worse to worst 😳) on ECG #ecg #ekg | ECG Lectures with Reid

Nice voice over and visual explanation of complete heart block from @thevisualnurse! Be sure to check him out 👍 Complete heart blocks in 60 seconds! . Step 1: Is there one P wave per QRS? No? Step 2: Why? (The PR interval tells the story) . In the example above we see an atrial rate of ~50-60 with a ventricular rate ~30, the inherent rates for each, respectively. The variable and changing PR interval confirms that atria and ventricles are each doing their own thing, contracting independent of o

🫀Complete heart block, aka third-degree atrioventricular (AV) block occurs when there is a complete interruption or blockage in the electrical signals between the upper chambers (atria) and lower chambers (ventricles). Because signals are getting blocked, there is no association between the P waves and the QRS complexes causing them both beat independently of each other. The atria maintain their own rhythm, and the ventricles establish a separate rhythm.⁣ ⁣ 𝗦𝘆𝗺𝗽𝘁𝗼𝗺𝘀⁣ Patients with compl
