Systole
Patient was educated on systole as follows: When the ventricles are full with blood from the atria, the pressure in the ventricles increases. The electrical signal that was initiated will spread from the atrial musculature to AV node, located at the junction of right atrium and ventricle. From the AV node, the impulse will spread across the ventricular muscle, causing contraction of both the ventricles. The AV valves are still closed and so, will prevent [...]
