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...
