Cardiac EKG Rhythms (2023/2024). Normal Sinus Rhythm ● Rate: 60-100 beats per minute ● Rhythm: Atrial and Ventricular Regular ● P Wave: Uniform in appearance, upright, normal shape, one preceding each QRS complex ● PR Interval: 0.12- 0.2 seconds ● QRS: 0.12 second or less. (If larger than 0.12- QRS is wide and there may be a bundle branch block) Sinus Bradycardia ● Rate: Less than 60 beats per minute ● Rhythm: Atrial and Ventricular Regular ● P Waves: Uniform in appear...
