8 Οκτ 2024 · ECG features of normal sinus rhythm. Regular rhythm at a rate of 60-100 bpm (or age-appropriate rate in children) Each QRS complex is preceded by a normal P wave. Normal P wave axis: P waves upright in leads I and II, inverted in aVR. The PR interval remains constant.
Learn how to interpret the ECG using an algorithm that covers rhythm, rate, axis, QRS complex, ST segment, T wave, PR interval and QT interval. See examples of normal and abnormal ECG findings and their causes.
Definition (criteria) for sinus rhythm. Regular rhythm with ventricular rate between 50 and 100 beats/min. P-wave with constant morphology preceding every QRS complex. The P-wave is positive in lead II. Figure 1 (below) shows normal sinus rhythm at paper speed 25 mm/s.
Comprehensive tutorial on ECG interpretation, covering normal waves, durations, intervals, rhythm and abnormal findings. From basic to advanced ECG reading. Includes a complete e-book, video lectures, clinical management, guidelines and much more.
8 Νοε 2021 · A normal sinus rhythm refers to both a normal heart rate and rhythm. Normal heart rates are from 60 to 100 beats per minute. The shape of the electrocardiogram (EKG) tracing will exhibit certain key attributes to be considered normal, as discussed below.
5 Μαΐ 2022 · When an EKG tracing meets these criteria —sinus-originating, fixed P-QRS-T repeating pattern, and HR between 60 and 99— it can be called Normal Sinus Rhythm. Normal Sinus Rhythm means: An EKG rhythm starting at the SA Node with a rate between 60 and 99 which follows the expected electrical path through the heart.
A regular heart rhythm originating from the sinoatrial node, characterized by a rate of 60-100 beats per minute, upright P waves before each QRS complex, and a consistent PR interval.
