  1. Oct 8, 2024 · Sinus bradycardia = sinus rhythm with resting heart rate < 60 bpm in adults, or below the normal range for age in children. Sinus arrhythmia = sinus rhythm with a beat-to-beat variation in the P-P interval (the time between successive P waves), producing an irregular ventricular rate.

  2. Oct 1, 2024 · 7 step approach to ECG rhythm analysis. 1. Rate. Tachycardia or bradycardia? Normal rate is 60-100/min. 2. Pattern of QRS complexes. Regular or irregular? If irregular is it regularly irregular or irregularly irregular? 3. QRS morphology. Narrow complex: sinus, atrial or junctional origin.

  4. Sinus rhythm is the normal rhythm of the heart and no treatment is relevant. Learn the definition, physiology, criteria for sinus rhythm, with emphasis on ECG interpretation. Arrhythmias from the sinoatrial node are also discussed.

  5. The rhythm is regular with consistent R-R intervals. Atrial and ventricular rates between 60 – 100 beats per minute (bpm) Each QRS complex is preceded by a distinct P wave. The PR interval remains constant and within the normal range (0.12 – 0.20 secs) The QRS complex width is narrow (<0.12 secs) A palpable pulse and measurable blood ...

  7. Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant.
