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.
Leads are small wires that run from the pulse generator to your heart muscle. Pacemakers are generally used to treat two types of arrhythmias.: 1  tachycardia-a heartbeat that is too fast. 2  bradycardia-a heartbeat that is too slow.
