+<p>A healthy heart has a regular sequence of activations, while a diseased heart has irregular activations, which leads to insufficient plumbing of blood. In the United States, it is estimated that 12 million people will have atrial fibrillation in 2030. It contributes to about 160 thousand deaths each year. Symptoms include fast heartbeat, chest pain, dizziness, shortness of breath, etc.</p>
