Following this delay, the electrical signal continues on to stimulate
the other ventricular cells 1/16 of a second later. The large ventricle, now

filled with large quantities of blood and whose turn has now come, con-
tracts and pumps blood in to the body. All these processes take place in
less than one second. 54
To sum up, the electrical current first emerges in the upper part of
the heart, in the SA node, ensuring that electricity is distributed through-
out the heart and that the heart’s muscle cells contract as it passes
55
moves. Yet the situation that comes about is very different from what
one would expect under normal conditions. The energy given off by the
generator should first stimulate the small atria and then the large ventri-
cles. Yet since the electrical wave moves very quickly, both pumps
should contract at almost the same time, and the heart’s work would be
seriously impaired. Yet this never happens, because all this has been tak-
en into account beforehand. So perfect is the design of the electrical cir-
cuit in our hearts that the electrical energy first stimulates the small atria,
is kept waiting for a time, and only then stimulates the large ventricles.
After the electrical signal has set out, the atria keep it waiting at a specif-
ic point until they have fulfilled their functions.
But the heart and blood vessels do more than speed up or slow the
blood circulation in response to the body’s needs. They carry blood to
different tissues to spark off different activities. Extra blood rushes to the
stomach when we eat, to our lungs and muscles when we run, and to the
brain when we think and speak. The heart and circulatory system com-
bine data just like a computer to meet the body’s various needs, and thus

respond in a way that no computer can. 56
The deceleration or acceleration of the heartbeat generally leads to
tightening of the chest and discomfort expressed in the form of palpita-
tions. The abnormal acceleration or deceleration of the heartbeat may re-
sult from disruptions in the heart’s electrical signals. In order to under-
stand rapid or slow palpitations, we need to examine how the normal
heartbeat comes about and acts throughout the heart.
