Sinus slow cause of disease and _ general knowledge of the clinical manifestation aroused in interest
Sinus slow cause of disease and clinical manifestation aroused in interest
The sinus has been aroused in interest and slow (sinusbradycardia) It is slow to originate from the medical education network aroused in interest of the knot of sinus room, it is slow to be abbreviated as the sinus.
Cause of disease
The sinus has been aroused in interest and slow and common in some physiological states, at the time of such as the athlete, physical labourer or sleep,etc.; Also drome etc. in the cranium that various causes of disease cause that at internal and external illness of some hearts, such as press increasing, jaundice, mucus edema, coronary heart disease, morbid state sinus room and form syndrome etc. in the cranium that various causes of disease cause t; Can also be caused by some medicines sometimes, such as the receptor blocks pharmaceutical, reserpine, foreign digitalis,etc..
Clinical manifestation
The physiology sinus has been aroused in interest and too slow to there is not symptom frequently, pathology and medicine sinus are aroused in interest and too slow besides cause of disease and inducement symptom, there can be uncomfortable palpitation, dizzy, weak medical education network,etc., the serious one can bring out fainting, the heart function is not complete, hypotension, even suffer from shock etc.. There is heart rate that is slowed down at the time of the physical examination ( lt; 60 times fen) ,But general gt; 40 times /divide,often as sinus arrhythmic (sinusarrhythmia) . If appear slowly but at the time of the regular heart rate, must distinguish with atrio-ventricular block of three degrees,etc., but distinguish now that easy according to the electric chart of heart. See " clinical diagnostics " in its characteristic of electrocardiogram.
The sinus aroused in interest and too slow is mainly caused by hypertonia of nervus vagus.
(1)Physiology: Normal people, especially participate in the physical training or strong physical labourer for a long time, there can be sinus nature aroused in interest and too slow. Sleep and fear, too can cause sex aroused in interest and too slow for the moment. For another example some tactics oppress the eyeball, press carotid sinus, vomit, the blood vessel faints etc., the causing the sinus can be aroused in interest and too slow.
(2)Medicine: - receptor blocks pharmaceutical, reserpine, guanethidine, morphine, foreign digitalis, the Kui 's, lidocaine, second amine iodine furan ketone, different to fight definitely, the causing the sinus can be aroused in interest and too slow.
(3)Whole body disease: The thyroid gland function fails, obstructive jaundice, press and increase in the cranium, some infection such as leptospirosis, typhoid fever, influenza, infective monocyte increase disease, convalescence such as diphtheria, hypophyseal the intersection of function and obtuse, high the intersection of blood and potassium, alkalosis, the intersection of gullet and diverticulum, depression, can cause sinus nature to be aroused in interest too slow
(4)Heart blood vessel disease: Acute myocardial infarction, chronic ischemic heart disease, the sinus room forms inflammation, membrane inflammation, pericarditis are invaded and the sinus room is formed in the myocarditis, heart, the sinus room forms thrombus, expansion, inflammation of the artery, some myocardium disease such as a kind of sex change of starch, getting stupid France the intersection of block of four and disease or trunk misplace postoperative, microorganism involve heart, bleed and enter the sinus room to form, the family sinus is aroused in interest and too slow, involve the heart and inhibit centre or disease of nervous system of centre,etc. that accelerated the centre, can cause the slow emergence aroused in interest.
