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 a deviation from the heart's normal beating pattern caused when the heart muscle is deprived of oxygen and is a dangerous side effect of a heart attack. A very fast or slow rhythmic heart rate often occurs in patients who have had a heart attack, and is not usually a dangerous sign.
