Sinus bradycardia
Ten Days After a Caesarean Delivery
A 28-year-old woman reports three days of palpitations and exertional breathlessness, ten days after a caesarean delivery.
Look for
- Sinus P waves preceding the QRS complexes.
- Adult heart rate below 60/min.
Where to look. In lead II, find P before each QRS; measure R–R intervals using the paper speed.
The rhythm is sinus but slow. Rate alone cannot establish its cause or whether it explains symptoms.
The published rate is 31/min; the cause cannot be inferred from the tracing.
