Penn's original name for the colony was to be New Wales, but that suggestion was rejected. Instead, he chose Sylvania (meaning woods) and it was modified by the King to Pennsylvania in honor of Penn's father. See Early Development . See also Indian Wars Time Table .
The four main types of arrhythmia are premature (extra) beats, supraventricular (SU-prah-ven-TRIK-yu-lar) arrhythmias, ventricular arrhythmias, and bradyarrhythmias (bray-de-ah-RITH-me-ahs). Premature beats are the most common type of arrhythmia. They're harmless most of the time and often don't cause any symptoms. When symptoms do occur, they usually feel like fluttering in the chest or a feeling of a skipped heartbeat. Most of the time, premature beats need no treatment, especially in healthy people.
An arrhythmia is an abnormality in the timing or pattern of the heartbeat. When you have an arrhythmia, your heart may beat too quickly or too slowly, or you may experience an irregular rhythm in which your heart feels as if it is skipping a beat.. Some types of arrhythmia may not be serious.
