sinus rhythm regular rhythm Set by SA node at 60 to 100 bpm P waves normal normal qrs PR 0.12 - 0.2 normal qrs less than 0.10 wide qrs is greater than 0.12 Sinus Tachycardia 100-160 bpm SA node reduced time for ventricle filling assess for SOB or chest pain a prolonged QT interval more prone to arrhythmia NSR reflects the heart's normal electrical activity, providing synchrony between the atria and the ventricles. Sinus tachycardia occurs when the sinus no...

Identify Dysrhythmia! Exam Questions And Answers 2 Lead ECG placement? The precordial leads, also known as chest leads or V leads, view the heart in the horizontal plane. They include six unipolar leads (V1, V2, V3, V4, V5, and V6) that measure electrical activity between the center of the heart and a positive electrode on the chest wall. Heart conduction 1. Sinoatrial node 2. Atrioventricular node 3. Atrioventricular bundle 4. Right and left bundle branches 5. Purkinje fibers ...
