Sinus rhythm with no major abnormality described
An ECG at Age 57
ECG from a 57-year-old woman with mild-to-moderate pulmonary valve stenosis. The reason for recording and symptoms are not supplied.
Look for
- Regular P waves preceding the QRS complexes.
- Consistent P–QRS relationship.
- No major abnormality reported in the source description.
Where to look. Start in lead II for the P–QRS relationship, then check all 12 leads.
Activation begins in the sinus node and then reaches the ventricles. A tracing described as normal does not exclude heart disease.
The known pulmonary stenosis illustrates that an ECG described as normal does not exclude heart disease.
