What is cardiac arrhythmia


Published on

Heart pump that ensures circulation in the body is a muscular organ, hollow, consisting of four cavities, two upper (atria) and two lower (ventricles). Each atrium communicates with the ventricle on the same side through a hole provided with valves which have the function of valves, valves allow blood flow one way, namely from the atria toward the ventricles. Hole on the right side has three valves and one of only two left.

Crossing this node electrical impulse rapidly excites all cells ventricles through His-Purkinje system called network. Electrical activity of the heart can be recorded with electrocardiogram to see if it is synchronized. Between beats, the electrical system is charging as well as heart muscle that between two contractions relaxes and fills with blood again. Therefore each contraction of the heart is triggered electrically. Repeating this phenomenon results heartbeat. Sinus node is the one that gives the measure of the pace. He has the ability to adjust the sensitivity cadence body needs to stimulate the nervous system and stimulating hormones (e.g. adrenaline). So accelerates heart rate during exertion or during an emotion and it slows down .Heart pumpHeart pump that ensures circulation in the body is a are normal heart rhythm disorders or in terms ofmuscular organ, hollow, consisting of four cavities, frequency or regularity of heart rate, or in both.two upper (atria) and two lower (ventricles).

It sends blood to the lungs where it isoxygenated before crossing the left atrium to the leftventricle to be directed to. Left ventricle, the mostvoluminous pumps blood into the arteries and hencethroughout the body.For the heart to pump blood effectively as billions ofcells in the upper chambers and the ventricles have tocontract simultaneously. This timing is triggered by anelectrical impulse. These actions are guided by the Variations in heart rate are normal in some cases.sinus node, located in the right atrium.
