normal 12 lead electrocardiogram labelled sinus rhythm
This ECG appears normal overall from the photo:
Normal sinus rhythm, rate about 68 bpm
Normal PR interval (about 156 ms), narrow QRS (about 86 ms), and normal QTc (about 401 ms)
Normal electrical axis
No clear atrial/ventricular enlargement, conduction block, significant ST-segment elevation/depression, or concerning T-wave inversion visible
The printed automated interpretation also reads: “Normal sinus rhythm / Normal ECG”
A photo cannot fully replace a clinician reviewing the original tracing in context. If this ECG was done for chest pain, fainting, breathlessness, palpitations, or new concerning symptoms, seek prompt medical assessment even if the resting ECG appears normal.
Compare this ECG with an older tracing
Reading File
Please upload the older ECG tracing (ideally a clear, full 12-lead image including the printed measurements and date). I’ll compare:
Rhythm and heart rate
PR, QRS, QT/QTc intervals and axis
ST segments and T waves
Any new conduction changes, Q waves, or chamber-enlargement patterns
If possible, include why each ECG was taken and any symptoms at the time.
