What Are the Signs and Symptoms of Atrial Fibrillation? Atrial fibrillation (AF) usually causes the heart's lower chambers, the ventricles, to contract faster than normal. When this happens, the ventricles can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body. This can lead to signs and symptoms, such as: 1  Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast) 2  Shortness of breath. 3  Weakness or problems exercising.  Chest 1  pain. Dizziness or fainting.  Fatigue 1  (tiredness) Confusion.

â¢ A subfloor is the bottom-most structural level of your floor. It supports your decorative floor finish, whether itâs carpet, hardwood, vinyl, laminated wood or tile. For more information, download this PDF. â¢ Floor preparation for installing tile depends on the type of subfloor in the room you are tiling. Concrete subfloors are prepared differently than wood subfloors. â¢ The subfloor should be able to hold the weight of the tile and preparation materials required to complete the installation.
