ECGWM

Electrocardiogram (ECG)

ECGWM is the WLMs model for the electrocardiogram, the recording of the heart's electrical activity. Its description, results and release details will be added here. Until then, this page shows what the signal looks like.

The signal

One heartbeat, wave by wave Illustrative

Every heartbeat leaves the same sequence of waves on an ECG. Their shape, size and timing are what clinicians and models read.

P wave
The upper chambers (atria) activate.
QRS complex
The lower chambers (ventricles) activate. In adults it normally lasts under 120 ms.
T wave
The ventricles recover before the next beat.
PR interval
Start of the P wave to the start of the QRS complex, normally 120 to 200 ms.
QT interval
Start of the QRS complex to the end of the T wave. It shortens as the heart beats faster.

Synthetic beat drawn at 60 beats per minute. Hover, or focus the chart and use the arrow keys, to read values.

Rhythm

No two beats are the same length Illustrative

The time between successive R peaks, the RR interval, rises and falls with breathing and slower regulation of the circulation. This is heart rate variability. Move the heart rate control above to see the pattern shift.

–Mean heart rate
–SDNN: standard deviation of RR intervals
–RMSSD: beat-to-beat variation

120 synthetic beats. The values describe this illustration only.
