The hearts pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. Heart rate regularity of beats sites where electrical impulses originate or sequence of activation of heartbeats.

Heart electrical diagram. This amazing muscle produces electrical impulses that cause the heart to contract pumping blood throughout the body. Like all muscle the heart needs a source of energy and oxygen to function. This is commonly called the heart natural pacemaker in human heart diagram. The hearts electrical signal is produced by a tiny structure known as the sinus node which is located in the upper portion of the right atrium. In the simplest terms the heart is a pump made up of muscle tissue. The electrical impulse generally travels from the sinus node through the muscle to the atriums and causing them to contract and also push the blood in the ventricles.
Normally the electrical impulse is generated by a special part of the atrium which called the sinus node. Your hearts electrical system controls the rate and rhythm of your heartbeat. Heart rhythm disorders involve abnormalities of one or more of the following. The heart and the circulatory system together form the cardiovascular system. Heart rhythm disorder is also referred to as an arrhythmia. This diagram correlates an ecg tracing with the electrical and mechanical events of a heart contraction.
A heart rhythm disorder is an abnormal variation from the normal heartbeat. The anatomy of the hearts chambers and valves includes two atria at the top of the heart with two ventricles at the bottom. Electrical signals arising in the sa node located in the right atrium stimulate the atria to contractthen the signals travel to the atrioventricular node av node which is located in the interatrial septumafter a delay the electrical signal diverges and is conducted through the left and right bundle of his to the respective purkinje fibers for each side of the heart as well as to the. Each segment of an ecg tracing corresponds to one event in the cardiac cycle. Webmds heart anatomy page provides a detailed image of the heart and provides information on heart conditions tests and treatments. If disease or injury weakens your heart your bodys organs will not receive enough blood to work normally.
A problem with the electrical systemor the nervous or. A healthy heart supplies your body with the right amount of blood at the rate needed to work well. The heart is situated within the chest cavity and surrounded by a fluid filled sac called the pericardium. The hearts electrical system. Visit this site for a more detailed analysis of ecgs.
