Hi. Along with low pulse rate does she have any symptoms like giddiness fainting or extreme tiredness? Does her pulse rate increase proportionately with physical activity like when she walks around or does some household work?
Why was orcibest started? Any ECG or Echo or Holter test etc done? Low resting pulse rate can be due to many causes and if symptomatic or persistently below 50bpm needs to be evaluated
Next Steps
If she has symptomatic low pulse rate them she needs evaluation. also Details of her treatment for Ca breast needed. whether she received any radiotherapy chemotherapy etc. sometimes that can lead to cardiac issues.
