Im only 16 years old and I have a pulse rate between 80-100 or sometimes more . I have done many medical tests to rule out any underlying cause but nothing . Also , the internet says that those who have a slightly fast pulse die earlier ...
I can also see my belly pulsating so clearly that it scares me , and thanks to the internet that this is the symptom of aneurysm.
When I stand up straight I feel a pressure on chest with fast heartbeat . Which I also think is due to POTS( postural orthostatic tachycardia syndrome)
Please tell me is it possible to have so many issues at my age ? Also I have done Ekgs , echo and blood work.
