R00.1
DESCRIPTION
This rhythm does not require treatment, unless it is causing symptoms, i.e. syncope, dizziness, tiredness and poor effort tolerance.
Sinus bradycardia <50 bpm or sinus arrest with slow escape rhythm, accompanied by hypotension, strongly suggest a treatable underlying cause such as:
- acute inferior myocardial infarct,
- hyperkalaemia, especially if wide QRS and/or peaked T waves,
- medicines, especially combination of verapamil and ß-blocker or digoxin,
- hypothermia,
- hypoxia, or
- hypothyroidism.
Treat the cause. Consider atropine if inferior myocardial infarct.
