Just like skeletal muscles, heart muscles are electrically stimulated to contract. The result is reduced cardiac output-or a reduced amount of blood ejected from the heart. An electrocardiogram (ECG or EKG) is a register of the hearts electrical activity. If the electrical impulses traveling from the atria to the ventricles come early or late, the balance between blood filling the lower chambers and the timing of the heart’s contraction is disturbed. The AV node conducts the electrical impulses more slowly than other nodes to allow time for the ventricles to receive blood from the atria before they contract and send it out of the heart. The AV atria node is the only pathway for electrical impulses to travel to the ventricles. This interactive courseware provides up-to-date, accurate and visually explained ECG and chest pain education for all levels - novice to expert.

It then travels to the AV (atrioventricular) node, which is located between the (upper chambers) and the ventricles (lower chambers). imPULSE 2.0 is a multi-level, web-based education series designed for healthcare professionals. The impulse travels through the atrial muscles, causing them to contract. The sinus node, located in the heart’s upper right chamber (atrium), generates an electrical impulse each fraction of a second.

The tissues that generate electrical activity are called the sinus node (or sinoatrial node). With each contraction, the heart sends blood out to the lungs to pick up oxygen or to the body to deliver oxygen to the cells. These impulses cause the heart muscles to contract. Specialized tissues within the heart are capable of generating electrical impulses.

Identify abnormal levels of certain electrolytes, such as potassium and calcium, in the blood.It then travels to the AV (atrioventricular) node, which is located between the (upper. Determine the size of the heart chambers The impulse travels through the atrial muscles, causing them to contract.In addition to providing insight into the heart’s rhythm, the ECG helps doctors with the following: The shape and size of the waves, the time between each wave, and the rate and regularity of beating provide valuable information to doctors. The “T” wave – This wave reflects the heart’s return to rest.The “QRS” wave – This wave records electrical activity in the lower chambers of the heart.The “P” wave – This wave indicates the electrical impulse in the upper chambers of the heart.The heart’s electrical activity determines if it keeps a normal rhythm. When it does, treatment involves managing the underlying health condition, be it heart disease, high blood pressure, a congenital (present at birth) heart defect, or something else.An electrocardiogram (ECG or EKG) is a quick, painless test that measures the heart’s electrical activity and records any disturbances in heart rhythm in both children and adults. A pacemaker is almost always required.Īnother type of conduction disorder, bundle branch block, occurs when a blockage in the right or left bundle branch causes one ventricle to contract slightly slower than the other.īundle branch block by itself often does not require treatment.

If this happens, a person's pulse may dramatically slow, or there may be no pulse at all.

Third degree heart block: The most severe degree of heart block, in which electrical signals completely fail to reach the ventricles.Depending on the underlying cause of this condition, a pacemaker may need to be considered. Second degree heart block: In second degree AV block, some of the electrical impulses from the atria reach the ventricles, but some are blocked and never reach the ventricles.First degree heart block: The least severe degree of heart block, in which the electrical signals are slowed but still reach your ventricles.There are three degrees of heart block severity: In most cases of heart block, the electrical signals are weakened but do not stop completely. This interference prevents the atria from telling the ventricles when to contract and pump blood. Heart block is a conduction disorder in which the heart's electrical signals are unable to move from the atria to the ventricles.
