i have a galaxy 965 sport watch that provided first indication i had atrial flutter. i was sitting watching tv when watch alarm sounded and indicated i had sitting HR of 144. NO OTHER INDICATIONS! no pain no nausea no weakness, etc just the watch alarm. went to emergency. room. and they verified flutter and “ultimately” i was prescribed metoprolol and blood thinner (eliquis 5mg). because i also take prozac my prescription was lowered from 100 to 50mg. no further heart flutter.
HOWEVER: i am very active (mountain bike and running) and with metoprolol i find my heart rate is drastically affected. rides/runs at up to 150 bpm are now restricted to around 100 bmp before i go into 02 debt. i also experience weakness and fatigue i am so frustrated. today i made an appointment with my cardiologist (i’m retired military using landstuhl hospital in germany) to reduce or preferably stop using metoprolol. without my garmin 965 i would NEVER have had an induction i had a heart problem.
