Palpitation is an awareness of the abnormal beating of the heart. It may occur in people with or without heart problems. Heart palpitations when lying down is not a common occurrence and can be caused by various factors.
Flat feet occur when the normal foot arches have partially or completely collapsed. When the foot is put to the ground the inner or middle side of the foot comes down to the floor rather than remaining raised. This can cause the whole foot to roll inwards (this is called over-pronation).
Pronation refers to the inward roll of the foot during normal motion and occurs as the outer edge of the heel strikes the ground and the foot rolls inward and flattens out.A moderate amount of pronation is required for the foot to function properly, however damage and injury can occur during excessive pronation.When excessive pronation does occur the foot arch flattens out and stretches the muscles, tendons and ligaments underneath the foot. moderate amount of pronation is required for the foot to function properly, however damage and injury can occur during excessive pronation.
