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.
