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.
An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat. Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.
