Reference (normal) values for ECG (electrocardiography)
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.
How to Read EKG/ECG Electrocardiogram Results - Nurse.org
2024年8月23日 · A normal heart rhythm contains a P wave, a QRS, and a T wave.³ Knowing the normal amplitude, deflection, and duration of each component is essential to accurate rhythm and EKG/ECG interpretation. Amplitude: This measures the voltage of the beat and is determined by how high the wave reaches, as measured by each square vertically on the chart ...
How to Check Your ECG Report for Normal Results? Full Guide
2024年8月10日 · A normal ECG report typically shows a regular rhythm and consistent spacing between the waves and tracings. However, abnormalities such as irregular rhythms, changes in a wave shape, or variations in spacing can indicate potential heart …
ECG interpretation: Characteristics of the normal ECG (P ... - ECG …
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.
Normal ECG - Queen's U
A normal ECG is illustrated above. Note that the heart is beating in a regular sinus rhythm between 60 - 100 beats per minute (specifically 82 bpm). All the important intervals on this recording are within normal ranges. 1. P wave: upright in leads I, aVF and V3 - V6; normal duration of less than or equal to 0.11 seconds

3. Characteristics of the Normal ECG - University of Utah
In the normal ECG the T wave is always upright in leads I, II, V3-6, and always inverted in lead aVR. Normal ST segment elevation: this occurs in leads with large S waves (e.g., V1-3), and the normal configuration is concave upward.
