Transcript of Human Anatomy Heat Defect

BY: MAKENNAH LEWIS Arrhythmia DEFINITION STRUCTURES & SCIENTIFIC EXPLANATION Arrhythmia refers to any change from the normal sequence of electrical impulses within the heart. The electrical impulses may occur too fast or too slow, or erratically. This causes the heart to, when not beating properly, to not pump blood effectively. When that happens, the lungs, brain and all other organs can't work properly and may shut down or be extremely damaged. SYMPTOMS AND TREATMENTS -Feeling the heart beat abnormally fast (palpitation)
-Shortness of breath
-Chest pain
-Cardiac arrest

Monitor your pulse, prevent blood cots and restore heart rhythm. The heart is a powerful muscle that pumps blood throughout the body by means of a coordinated contraction. The contraction is generated by an electrical activation, which is spread by a wave of bio-electricity that propagates in a coordinated manner throughout the heart. Under normal conditions, the senatorial node initiates an electrical impulse that flows through the atria to ventricular node. This elevates the voltage at each cell. Normal rhythm is altered when one or more spiral waves of electricity activity appear. these waves are life threatening because they act as high-frequency sources and underlie complex cardiac dynamics such as fibrillation.
