I am a 27 year old, and have been diagnosed with anxiety, due to my dizziness, occasional chest and arm pain, and basically feeling bad really frequently. While I believe a lot of my issues could be mentally related, I am unsure if it is the whole story. The anxiety was diagnosed after blood tests, echo, ECG and holter earlier this year were all fine.
However, I became increasingly aware of my heart rate. I've noticed that my resting heart rate can go to low 50's, while when doing normal activities such as walking etc. it is usually in 100-110s. Do you have any comments on this?
Additionally, using my chest strap I have recorded the following exercise (I am confident it is correct, since I checked with my blood pressure monitor which recognises irregular beats): I start measuring my heart rate while sitting, then suddenly get up and after 5 seconds I suddenly sit down again. As expected the heart rate goes up after standing up, but there is a really irregularly slow beat when I sit down, after which my rate adjusts to what it was. I am attaching a picture ( i stood up when there is a small spike up, while I sat down when there is a huge surge down).
Could you please tell me if this is worrisome, and should I request additional investigation by cardiologist?
Thank you so much.
