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.
Atrial fibrillation is the most common type of heart arrhythmia â this occurs when the normal beating in the upper chambers of the heart is irregular, and blood doesnât flow as well as it should from the atria (upper chambers) to the lower chambers of the heart. When a heartbeat is too fast, this is called tachycardia.
