High heart rate without high extertion during exercise

Patient

Q: Hi, i was working out at the gym today on the cross trainer (not particularly pushing myself) but my screen flashed saying I had hit 175bpm. i'm 29. i was worried this may indicate disease of my heart. i had my heart checked out last september with blood tests and ecgs and have also had a 24hr ecg in may which all came back negative. i'm currently on trimethoprim for a suspected UTI and had forgotten my water bottle so was having to keep stopping to take sips from the water fountain. i'm not sure how big a part dehydration has to play or if i was dehydrated. i usually work out and struggle to get above 156 (i worked out yesterday and it was 156). i'm mainly concerned as i didnt have to do much exertion in order to reach that whereas before if i had id be puffing and panting and sore. i'm also transgender male (previously female and on nebido testosterone for 5years)

Symptoms:  thirsty, high heart rate (84 after walking home, 74 tested 5 mins later after drinking water), slight headache for a minute,
