I got covid in month of may, was negative 14 days later. I have been vaccinated with my first dose and its been 5 days. Today i was feeling a bit low so I slept in afternoon and when I woke up I was feeling short of breath and sweaty. I checked my saturation and oximeter showed 235 as my heart rate, again checked again it showed 230+, mu mother checked through it, it showed 105. Then I got it checked through blood Pressure device and results were, 125/80 and heart rate was 105. My other oximeter showed heart rate as 90-105 I'm worried. I did mu ecg in June and it was normal I'm worried How can it be 235
