St. Helens Chronicle. August 18 at 7:00pm Â·. I would suggest the City of St. Helens contact Boise, ask for at least one-half the cost of this cleanup of this PP and, if they do not agree, the City of St. Helens should bring suit against Boise for knowingly polluting and contaminating our environment.
Some types of arrhythmias, such as ventricular tachycardia, are serious and even life threatening. In the United States, arrhythmias are the primary cause of sudden cardiac death, accounting for more than 350,000 deaths each year.
Ventricular arrhythmias occur in the lower chambers of the heart, called the ventricles. Supraventricular arrhythmias occur in the area above the ventricles, usually in the upper chambers of the heart, called the atria. The irregular beats can either be too slow (bradycardia) or too fast (tachycardia).
