Distribution of fluid between these two compartments depends on a balance between hydrostatic pressure and osmotic pressure in the capillaries. An abnormal pattern of conduction through the heart. Most common type of arrhythmia. Interference with conduction through the AV node. Very rapid, coordinated contractions of the atria.
Ventricular rate is nearly normal due to the long refractory period of the AV node.
No pumping by atria. Ejection from the ventricles is almost normal. Very rapid, uncoordinated contractions of the ventricles. No recognizable rhythm. Determine the time spent in systole and diastole .
