Are my heart monitor findings dangerous?

[Kybball11]

HI, I am a 17 year old male. 5'6 weighing 140LBS. I was extremely active the first 15 years of my life and have a good resting heart rate of around 65. I have been experiencing chest pain, lightheadness, tachycardia(very brief runs), and pvcs for about 2 years now. My cardiologist has put me onto a 30 day event monitor. I am three weeks into the monitor and here is what they've found. Pvcs on a moderate frequency. And wide-complex tachycardia last 4beats 6beats and 12beats the heart rate during these episodes varied from 125 to 150. When these happen i feel anxious, sweaty, chest pain, and lightheaded, and very weak. I went in to see my doctor and he has told me over and over that this is not going to kill me, that i have a structurally normal heart (he did an echo just to be safe) he says he understands my worriness but that it seems benign. He agrees that the symptoms are an issue and wants to do a tilt table test and then decide what medication to give me to help me. He said the words i will fix you do not worry. I am starting to wonder and I am just wanting everyones thoughts. Should I get a second opinion? Is what  I have really dangerous? Is what I am experiecing consider non-sustained VTach? I have very little exercise tolerence, hot weather makes it worse, my arms and legs feel strange sometimes, and it has made me very anxious. Please any opinions are helpful :)

Thanks again for the support :) and it is very rough being so young and being sick because i have that urge to go and go but i do know i cant right now until I get feeling better so I am here with my grandmother and my girlfriend, I have started college taking my courses online for now until I get to feeling better, and helping around the house, I make sure to stay away from energy drinks you are right they are a big thing and should be banned forsure! I should get more rest my palpitations and woriness about them seems to help me loose sleep, I have started eating well but should start taking vitamins regularly. I will be sure to let you know about the results of the test, and my EP is supposed to contact me today so hopefully we will get something done soon enough :) It is in gods hands I suppose!

You're right about the stress. It is the biggest culprit for me too. You're young and I'm sure you have a lot going on and then to have your heart bounce around in your chest is very unnerving. I have grandkids your age and they are so busy going here and there and never get 8 hours of sleep. Getting enough rest is very important...not a fun thing for a teenager. Do you take vitamins and eat right? Very important. Some of my grandkids drink those energy drinks like red bull and I keep telling them how bad they are for the heart but they seem to be the big thing right now. I think they should be banned!!! Good for you for staying away from those things. Sounds like you're in the best care and just trust your ep. I started having palpitations early in my 20's, a few at first and during the years they've been different more bothersome than at other times. Good luck. I'd be interested in the results of your tilt table test.

Thank u for taking the time to respond :) and I am going to an EP here, one of the best in the state at a research institution thats ranked in the top 50 research hospitals in the country, so i know i should trust him but i get so nervous with these palps. that i second guess everything now a days :( I was drinking allot of caffeine when they first started years ago so i have stopped that have not touched it in a year and a half no smoking drinking or drugs. Exercise makes it worse, and emotional stress is the worst it makes it much worse

thank u for your support :)

Are you going to a regular cardio or an electorphysiologist? If you're not going to an "ep", I would consider that as a second opinion. He would be the expert on electrical problems with the heart.

In the meantime, watch what you eat and drink. For many of us with electrical problems, caffeine, too much chocolate and other things really trigger the arrythmias. Do you know if there was anything that triggered your arrythmias two years ago? Part of trying to get this figured out is to evaluate things you think might trigger these.
