What is a normal ECG result?
A normal Electrocardiogram (ECG) result indicates that the electrical activity of the heart is functioning within expected parameters. This includes factors like heart rate, rhythm, and the timing and shape of the electrical waves (P wave, QRS complex, T wave) that correspond to different phases of the heart's beat.
Based on the provided reference from Care Hospitals, a normal ECG result typically falls within the following ranges for various measurements:
| Measuring | Men | Women |
|---|---|---|
| Heart Rate | 49 to 100 BPM | 55 to 108 BPM |
| P Wave Length | 81 to 130 MS | 84 to 130 MS |
| PR Interval | 119 to 210 MS | 120 to 202 MS |
| QRS Duration | 74 to 110 MS | 78–88 MS |
- Heart Rate: This measures how fast your heart is beating. The normal range varies slightly between men and women according to the reference. BPM stands for beats per minute.
- P Wave Length: The P wave represents the electrical activation of the atria (the heart's upper chambers). Its length indicates the duration of this activation. MS stands for milliseconds.
- PR Interval: This measures the time it takes for the electrical impulse to travel from the atria to the ventricles (the heart's lower chambers). It includes the P wave and the segment before the QRS complex.
- QRS Duration: The QRS complex represents the electrical activation of the ventricles. Its duration shows how long this activation takes.
These specific ranges help healthcare professionals assess whether the heart's electrical signals are traveling along the correct path and at a normal speed, which is crucial for effective pumping.
