The Symptoms for Left sided Heart Failure
- Dyspnea
- Dyspnea on exertion
- Orthopnea
- Paroxysmal nocturnal dyspnea
Dyspnea A sense of breathlessness, initially on exertion than on rest also. The dyspnea is maximal when congestion of the lung is greatest as in exercise and lying flat.
Dyspnea on exertion In early-stage dyspnea is noticeable during physical activity and is called dyspnea on exertion. It results from increased venous congestion during physical activity.
Orthopnea Dyspnea on lying flat is called orthopnea. It results from an increased amount of venous return to thorax from the lower extremities when a patient is in lying position. The heart is unable to pump all of this venous return that leads to lung congestion and dyspnea.
Paroxysmal nocturnal dyspnea Dyspnea during sleep which awakens the patient with severe breathlessness, accompanied by a choking sensation and coughing is called paroxysmal nocturnal dyspnea. It also results from increased venous congestion as the patient is lying on the bed.
The Signs of Left-sided Heart Failure
Tachycardia, cardiomegaly, third heart sound, and fine crept at the lung bases. Chronic dilation of left atrium may also occur which may be associated with atrial fibrillation.Types of Heart Failure and Causes
