5. Medications
Most prescription medications do more than target the ailment for which they were prescribed. Several medications that are helpful in treating other conditions can have a negative effect on the heart and the cardiovascular system. There have been studies that show certain medications may even cause the development of bigeminy or exacerbate the bigeminy that is already present in an individual.
Herbal and natural supplements may also affect the body in ways that are not always predictable Some herbal supplements that are used to help control blood pressure and anxiety have also been noted to trigger bigeminy in some people. Aside from medications, there are instances where black market drugs and illicit substances have caused bigeminy.
Substances that increase the heart rate such as codeine, methamphetamines, amphetamines, cocaine, heroin and the like can cause bigeminy to develop among other harmful complications. The severity of bigeminy will vary from person to person.
