Detailed explanation-1: -The pacemaker or Sino Atrial Node is situated in the upper right corner of the walls of the right atrium of the heart.
Detailed explanation-2: -Your heart’s sinus node is your natural pacemaker (found in the upper right chamber of the heart, known as the atrium). It sends an electrical impulse to make your heart beat.
Detailed explanation-3: -A pacemaker insertion is the implantation of a small electronic device that is usually placed in the chest (just below the collarbone) to help regulate slow electrical problems with the heart.
Detailed explanation-4: -The sinus node is sometimes called the heart’s “natural pacemaker.” Each time the sinus node generates a new electrical impulse; that impulse spreads out through the heart’s upper chambers, called the right atrium and the left atrium (figure 2).
