The normal, healthy heart has its own pacemaker that regulates the rate that the heart beats. However, some hearts don't beat regularly. A pacemaker can sometimes correct the problem. A pacemaker is a small device that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm. A pacemaker may also be used to treat fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy.
The core of the treaty defined the Mexican Cession, the territory that Mexico was obliged to cede to the United States as a result of the war. The Mexican War was the culmination of a series of conflicts between Mexico and the United States.
The treaty in draft form was brought to Mexico by Nicholas P. Trist, the U.S. peace commissioner, in the summer of 1847. In its basic form it called for the cession of Alta and Baja California and New Mexico, the right of transit across the Tehuantepec isthmus, and the Rio Grande as the southern border of Texas. In exchange the United States would pay up to $20 million to Mexico and assume up to $3 million in U.S. citizens' claims against Mexico.
