Tachycardia.: A fast heart beat can have numerous causes and etiologies. If it happens in a moment, and you can figure out why (stress, too much caffeine, got scared by something), then you can wait it out and see if it gets better. If it seems to happen for no reason, then an evaluation by a Cardiologist would be in order to determine etiology.
