Stimulants: Stimulants increase the heart rate and make the heart more irritable and prone to irregular rhythms that would be perceived as palpitations. In addition to increasing the heart rate, some increase the strenght of the hear beat resulting in more blood being pumped that may cause a murmur, even in the absence of a heart defect. These stimulant may be ingested substances or internally produced.
