You need "urgent care" and yet here you are, venting to anonymous people and wasting bandwidth on the internet.
A friend of mine, outwardly healthy and in his late 50's was referred to a cardiologist after his annual medical exam indicated low heart beat, around 50 bpm. He now has a pacemaker (I think he's on his third battery by now).
More recently, another acquaintance was spooked after Googling a medical term related to cardiology that was used by his local doctor. He went to the government hospital, where after several hours waiting and flitting between departments, he saw a cardiologist who ran several tests/scan and said the word related to a non life-threatening condition, and he had nothing to worry about. For his troubles, he did subsequently get Covid.
Don't know what is more dangerous, Google or Government hospitals.
