Heart blocks slows impulse and lengthens the QRS complex of ECG; over all lowers the pulse
In second-degree heart block, not every impulse reaches its destination.

Page 33 and 34. There are three hearts on the dice in block #3. Two hearts on the sunglasses in block #2. One heart bead(O in YOU) on the bracelet in block #12. The seventh heart we still cannot find. Hope this helps. Update: The final heart is on the race car on block #7. Look on the front part of the car between the two front wheels.
The term for a delay or interruption in conduction of the electrical impulse in the myocardium is "heart block." Heart blocks can range from first-degree (mildest) to third-degree (most severe) based on the extent of conduction disruption in the heart's electrical system.
In the human heart, contraction is initiated by a special modified heart muscle known as sinoatrial node. It is located in the right atrium. The SA node has the inherent power of generating a wave of contraction and controlling the heart beat. Hence, it is known as the pacemaker. Since the heart beat is initiated by the SA node and the impulse of contraction originates in the heart itself, the human heart is termed myogenic. The hearts of vertebrates and molluscs are also myogenic.

Heart of Hearts was created in 1975-07.
It is the ability of the heart to send an electrical impulse on its own.

The movement of electrical impulses in the heart coordinates the contraction of its chambers. The impulses initiate the contraction by stimulating the muscle cells, causing them to contract in a coordinated way. This results in the rhythmic pumping action that drives blood flow through the heart and to the rest of the body.
