80 years. Frequent low BP after taking bike ride, eating breakfast and drinking 1 qt plus. Concerning?
Patient: I am 80 yrs old. At 0600 this am my BP was 147/92 pulse 55. I went on a 55 miles bike ride ,avg 11 mph. Stoped for a good bkfast , drank 1 qt plus. BP 15 min after ride 89/55 pulse 77. Three hrs later BP 124/79 pulse 72. This situation has been happening even with shorter rides(but more intense) Temp today, sun & 78F. I'm a bit worried. Doctor: Hello, Thanks for the query to H.C.M. Forum. The Blood pressure is not too high , but the cause of concern is bradycardia ( decreased pulse rate 55 / minute). 2nd time after breakfast B p was low . In my opinion this is not related to bike riding  , but may be  due to some heart ailment . 55 pulse / minute  is an indication of  cardiac failure so please consult  a cardiologist and get his opinion. Good luck. Dr. HET
