Jo-Anna s resting heart rate is 37.....she is extremely atheltic and has never shown any symptons of shortness of breath, fatigue, etc.  she is 53 and was climbing volcanoes and scuba diving last december.  now, she is a canidate for knee surgery and apparently the hospital here in mexico is concerned because her heart rate is slow.  they are sending her to a cardiologist today  can she have surgery to repair the meniscus, knee alignment and possibly the anterior cartiledge thank you, leonel.
Hi, I guess she is not on any Chat Doctor.  She is an athlete, her rate would be low. Still other causes like thyroid illness and age related issues should be evaluated. Probably cardiologist will get one holder monitoring done and determine the minimal heart she gets in 24 hours period and accordingly advise. She will mostly undergo surgery and probably cardiologist will clear her surgery, unless some serious issue is found, which is less likely. Hope I have answered your query. Let me know if I can assist you further.
