3. ECG Rhythm Interpretation A heart rhythm that originates in the sinoatrial node and is normally conducted is called a Normal Sinus Rhythm .The characteristics of a normal sinus rhythm are a regular rate between 60-100 beats per minute, a narrow complex, preceded by a P-wave where all the complexes look the same. http://medipptx.blogspot.com/2010/05/ecg-rhythm-interpretation_5088.html
4. Normal Sinus Rhythm Sinus rhythm is characterized by a usual rate of anywhere between 60-100 bpm. Every QRS complex is preceded by a P wave. The P wave morphology and axis must be normal and the PR interval will usually be 120 ms to 200 ms. http://medipptx.blogspot.com/2010/06/normal-sinus-rhythm_9695.html
