Third-degree or complete heart block is when electrical signals do not travel between the upper and lower chambers of the heart. These channels have specific ion selectivity and are responsible for the precise and timely regulation of the passage of charged ions across the cell membrane in myocytes and the summation of their activity in cardiac muscle defines the surface electrocardiogram. Pulseless electrical activity PEA refers to a medical condition in which the electrical activity or rhythm of a persons heart is relatively normal but the mechanical pumping action of the heart does not respond.
