WitrynaElectrical activity is the study of the electrical properties of biological cells, tissues and organs. It includes measurements of change in voltage or electric current on a far-ranging variety of scales from single ion channel proteins to entire organs like the heart. Human electrical energy is generated by chemical processes in nerve cells.

WitrynaPEA is a clinical state characterized by the presence of electrical activity in the absence of detectable cardiac output. This is a preterminal condition that often leads to … Pulseless electrical activity (PEA) refers to cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests and about 50% of in-hospital cardiac arrests. Under … Zobacz więcej Pulseless electrical activity leads to a loss of cardiac output, and the blood supply to the brain is interrupted. As a result, PEA is usually noticed when a person loses consciousness and stops breathing spontaneously. … Zobacz więcej The absence of a pulse confirms a clinical diagnosis of cardiac arrest, but PEA can only be distinguished from other causes of cardiac arrest with a device capable of Zobacz więcej These possible causes are remembered as the 6 Hs and the 6 Ts.
