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.
To Mexico, the loss of an enormous part of its territory was a tremendous embarrassment and created lasting anger among many of its citizens. Under the terms of the cession, the United States acquired the territory that became the states of California, Nevada, Utah, and Arizona, with the exception of that territory that later was added by the Gadsden Treaty in 1853. The price of this was $15 million to Mexico and $3,250,000 to cover the claims of American citizens against Mexico.
