A "normal ECG level" isn't a single value, but rather a range of values for different measurements within an electrocardiogram (ECG) reading. These ranges differ slightly between men and women.
Here's a breakdown of normal ECG ranges:
Normal ECG Values for Men and Women
| MEASUREMENT | MEN | WOMEN |
|---|---|---|
| Heart Rate | 49 to 100 BPM | 55 to 108 BPM |
| P Wavelength | 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 |
Important Considerations:
- Heart Rate: Measures the number of heartbeats per minute (BPM). Normal ranges typically fall between 60 and 100 BPM, but some sources cite slightly broader ranges as shown above.
- P Wavelength: Represents atrial depolarization (the electrical activity that causes the atria to contract).
- PR Interval: Represents the time it takes for the electrical impulse to travel from the atria to the ventricles.
- QRS Duration: Represents ventricular depolarization (the electrical activity that causes the ventricles to contract).
Disclaimer: These ranges are general guidelines. A doctor should always interpret ECG results within the context of a patient's overall health and medical history. Minor variations outside these ranges may be normal for some individuals. A single abnormal value does not necessarily indicate a problem.
