Hello, im 21, today at the gym i was on the cross trainer for under 10 minutes, i wasnt working hard at all and wasnt tired. the heart rate read 196. i am a tiny bit worried because when i used to run more regularly i used to blackout after going for runs. Im not sure if i should seek help or not
Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that it is normal to have an increased heart rate during physical activity, especially when you are not performing regularly physical activity and your body can be over-stressed by the physical exercise. The episodes of blackouts after going for runs are a little concerning. They could be related to a low blood pressure (orthostatic hypotension), low blood glucose, hyperventilation or cardiac arrhythmia. I recommend you to consult with your GP for a careful physical examination, a resting ECG, a chest X-ray study and some blood lab tests
