Sinus rhythm with no major abnormality described
An ECG to Interpret at Age 66
ECG from a 66-year-old man. 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.
Available information does not justify adding symptoms or a reason for presentation.
