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.
What is an arrhythmia (heart rhythm disorder)? Arrhythmias are abnormalities of the heartbeat. There are many types of arrhythmias, and they are classified by some researchers and doctors by where they begin in the heart (the atria, AV node, or the ventricles). Others classify arrhythmias as one of four types -- premature beats, supraventricular, ventricular, and bradyarrhythmias.
