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.
This was known as the Mexican Cession and included present-day Arizona and New Mexico and parts of Utah, Nevada, and Colorado (see Article V of the treaty). Mexico relinquished all claims to Texas and recognized the Rio Grande as the southern boundary with the United States (see Article V).olk chose to forward the treaty to the Senate. When the Senate reluctantly ratified the treaty (by a vote of 34 to 14) on March 10, 1848, it deleted Article X guaranteeing the protection of Mexican land grants.
