Hello doctor. I'm 21 yo. I have no history of heart attack or any such condition. Yet sometimes while I sitting or doing some work, I feel one or two strong beats in my chest. It's doesn't make me unconscious or anything. I just sit for two seconds and wait for them to go away on its own. It's does last for more than 2 secs. I Googled and I came to know there is a condition called VT. Now I'm SCARED. I'm just 21. My anxiety is through the roof. Even worse than before. I cannot sleep. I cannot do my work. I cannot study. I'm anxious ALL THE TIME. My brain starts coming up with these horrible horrible scenarios. Life has become miserable.
