Possible heart condition
Over the last six months, I've had several of what I would describe as "heart spells." On two different occasions, while walking somewhere, my heart has inexplicably sped up (I would describe it as an irregular heartbeat; I don't know what my BPM was, but it was definitely higher than average). On the two occasions that these incidents have occurred, I have also begun perspiring profusely, though I wasn`t vigorously exercising at the time. The first spell was worse than the second. Though I never timed it, I would estimate that it lasted for roughly 20 minutes. There were no other symptoms indicative of a heart attack, though I could not breathe deeply. The second incident happened in a mall, earlier today. I sat down on a bench and put my head between my legs, and it lasted for perhaps five to eight minutes.
All of this seems very unusual for someone of my age. I`m 20 years old, male, roughly 6 foot 4 inches tall, and in decent shape. My build is about average, and my weight typical of someone of my height. I`m a non-smoker (never smoked), though I have been drinking a good deal more than usual since January of this year. Also, my diet could be a lot better (this isn`t a lifestyle choice; I`m simply a student, and can`t afford decent food). I`m worried that this could be a cholesterol problem or something. I do my best to exercise regularly, and, though I`m not in spectacular shape, I would, again, describe myself as roughly average. My problem is that I do not gain weight, because of my body build. In short, if I spend a week eating fast food and the like, I see no visible effects. I`m worried that this could be congesting my arteries or something similar. Also, it should be noted that, because of a physical condition I have, I tend to burn calories more rapidly than most people do.
I suspect that this could be something more benign, like gas trapped in my chest or something of the like. Even so, would you all recommend that I get this investigated? As I said, this has now happened twice, and I`m worried that it could escalate. Thanks in advance for the feedback.
