A typical ECG in AF shows no P waves and an irregular ventricular rate. AF is often treated with medications to slow the heart rate to a near normal range (known as rate control) or to convert the rhythm to normal sinus rhythm (known as rhythm control). Electrical cardioversion can also be used to convert AF to a normal sinus rhythm and is often used emergently if the person is unstable.
How does a water tower work? Water towers provide extra water storage for a town's water supply. They hold about a day's worth of water, so if the town's pumps fail (like during a power outage), the water tower acts as a backup water supply.
Water Pressure Tanks: What Are They and How Do They Work? When you open a spigot in your home, you expect water to flow at a certain speed. Water pressure in the line causes that water to flow. If your home is on city utilities, water pressure is controlled (for the most part) by the city. If your home is on a well, you need something to build that pressure and this is the purpose of the pressure tank. In a nutshell: The pressure tank in a water well system creates water pressure by using compressed air to bear down on the water. Because of this pressure, when a valve is opened water is pushed out of the tank through the pipes in your home.
