Could heart palpitations be fatal?

Heart palpatations: Palpitations are the sensation of an abnormal heart beat. Many types of irregular heartbeats are not harmful and are common for everyone throughout a normal day, we just do not feel them as palpitations, necessarily. However, some irregular heart beats are dangerous and require attention. This symptom should be reported immediately to your physician.

Sure, if...: This is possible if the palpitations are due to something called sustained ventricular tachycardia (or its kissing cousin, torsades). Otherwise, no, the palpitations are almost always an annoying, but not fatal problem.
