At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal. This chapter will focus on the ECG waves in terms of morphology (appearance), durations and intervals.
28 Φεβ 2011 · A simple, step-by-step guide to reading an ECG (also known as ECG interpretation), with included ECG examples and ECG quiz questions.
4 Νοε 2015 · The Normal ECG. Standard Calibration. A standard ECG is recorded at 25mm/sec and with a frequency cut off of no lower than 150Hz in adults, and 250Hz in children. On the standard ECG paper, with standard calibration, the squares represent:
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.

13 Σεπ 2021 · 1. Identify and Examine the P Waves. The P-Wave, located at the beginning of the ECG cycle, should be present and upright. A P-Wave that is absent or inverted is abnormal. The P-wave should also not be more than 1 large box tall and 1 large box wide.
