Once, serious abnormal heart rhythms or arrhythmia (ah-RITH-me-ah) required open-heart surgery to treat. 1  Fortunately, this is rarely the case today. Thanks to advances in medicines and medical devices, there are now safer and much more comfortable treatment options for abnormal heart rhythms.
Rhododendron /ËroÊdÉËdÉndrÉn/ (from Ancient Greek á¿¥ÏÎ´Î¿Î½ rhÃ³don rose and Î´Î­Î½Î´ÏÎ¿Î½ dÃ©ndron tree) is a genus of 1,024 species of woody plants in the heath family (Ericaceae), either evergreen or deciduous, and found mainly in Asia, although it is also widespread throughout the Southern Highlands of the Appalachian Mountains of North America.
In summary: Rhododendron is an introduced species. It is highly invasive. It destroys habitats and thus whole colonies of native plants and animals disappear. Because it is so expensive to control and physically prevents access, land has been abandoned.he reason for this is simple. Where conditions are suitable, Rhododendron will out compete most native plants. It will grow to many times the height of a person, allowing very little light to penetrate through its thick leaf canopy.
