An important symptom of heart disease is shortness of breath, which means weight breathing. The patient feels a shortness of breath or feel like suffocating. In this situation an increase of frequency and amplitude of the breathing movement is noticed. The syndrome is seen in mitral and aortic, hypertension, in pericarditis and myocarditis. All these diseases have one common characteristic: the blood is unable to travel easily to the left heart chambers and thus stagnates in the lungs, reducing the possibilities of exchanging gases, taking oxygen from the air and eliminate carbon dioxide. Stagnation of blood in lung capillaries network is accentuated by the fact that the right ventricle, being healthy, sends the same amount of normal heart blood, which the left ventricle, suffering, can not fully push forward. If such a patient is forced to do more exercise (climbing several stories), is a pretty long and intense dyspnea, which requires the patient to stop and rest.



Very often, especially after exercise, some pains may appear in the left side of chest. In some diseases such as angina, myocardial infarction and dry pericarditis, chest pain is very intense, being the dominant symptom of heart disease. In angina pectoris and myocardial infarction the pain is caused by poor irrigation of cardiac muscle, and in pericarditis it appears because of the friction between the pericardial foils, inflamed and thickened. Heartache can be also met in some cases of volume growth in certain rooms of the heart, which compresses the spine or sternum bone.

That sometimes happens in mitral stenosis when dilated left atrium causes back pain, in the shoulder blade region. But not all pain that is felt in the heart is caused suffering by this organ. For example, the exaggerated overgrowth of air in the stomach or intestine may be accompanied by localized pain in the heart, but in reality these are caused by the fact that the air bag, sometimes very large, clicks on the heart, especially when the one in cause is at rest on the left.
A heart beats day and night, but its rhythmic contractions don’t bother, when they become noticeable, there is an unpleasant sensation, discomfort, palpitation.



Normally there is a threshold of sensitivity nerve. Only when this is exceeded, heartbeats are known as palpitations. Some people show an increased state of excitability of the nervous system, because the sensitivity threshold is easily exceeded. In this category belong tired, emotive people, those who abuse tobacco, alcohol coffee, tea, and people with different disorders from the glands with internal secretion, those with higher gas retention in the stomach or intestine. All of them often complain of palpitations, although their heart is sick and her rhythm is normal.
