This is the natural pacemaker of the heart. It initiates all heartbeat and determines heart rate. Electrical impulses from the SA node spread throughout both atria and stimulate them to contract. - The atrioventricular node, or AV node, located on the other side of the right atrium, near the AV valve. The AV node serves as electrical gateway to the ventricles. It delays the passage of electrical impulses to the ventricles. This delay is to ensure that the atria have ejected all the blood into the ventricles before the ventricles contract. - The AV node receives signals from the SA node and passes them onto the atrioventricular bundle - AV bundle or bundle of His. - This bundle is then divided into right and left bundle branches which conduc

Draw sets of parallels, perpendicular to the first sets of parallels, corresponding to each digit of the second number (the multiplier). Put dots where each line crosses another line. On the left corner, put a curved line through the wide spot with no points. Do the same with the right. Count the points in the right corner. Count the points in the middle. Count the ones in the left corner. If the number on the right is greater than 9, carry and add the number in the tens place to the number in the middle (see fig. 2). If the number in the middle is greater than 9, do the same thing except add it to the number from the left corner. Write all those numb
