Is the slow sinus arrhythmia functional or organic? How to distinguish _'s general knowledge
The sinus aroused in interest can be seen to normal people slowly, especially athletes and to the elderly. Sinus aroused in interest and too slow usually, don't think electrocardiogram brief sinus on to be getting aroused in interest and slow to just suffer from serious heart disease. Especially the elderly, because physiological function fail, slowly what the heartbeat changed, this is that normal physiology makes a variation. The sinus aroused in interest and slow is not all bad thing to organisms, because the heartbeat is slow, the cardiac muscle is long at break, myocardium oxygen consumption is reduced, the ventricle is plentiful and good, make each heartbeat appearing amount increase. The sinus aroused in interest and slow does not usually cause symptom, there is no harmfulness.
Can present the sinus arrhythmia slowly in the following situations: 1, Athlete, the elderly, fan are absent-minded and is stimulated (carotid sinus is stimulated, pressed and increased in oesophageal diverticulum, cranium, or function of the medicine that the sympathetic nerve would rather block (reserpine, guanethidine, propranolol, gains,etc.) . 2,It is low that the supersession is reduced (thyroid gland function, hypophysis function failing, low temperature) . 3,Press increasing, obstructive jaundice, pituitary function and fail in obstructive jaundice, cranium. 4,A lot of medicine can also cause arrhythmia, if foreign digitalis excessive employing block pharmaceutical, can present sinus to be aroused in interest and too slow neat; Foreign digitalis is excessive, is poisoned and can also see the sinus stopping fighting in the Kui 's; Foreign digitalis, propranolol are excessive, poisoned and can block the sinus room in the Kui 's. 5,The electrolyte is disorderly ' Potassium) such as the high blood . 6,Disease of the atrium or sinus room knot: Acute or chronic coronary artery pathological change, myocarditis, the intersection of cardiac muscle and ill myocardium tumour, lasting the intersection of sinus and room block .
So, it is analyzed that the arrhythmia is functional, organic, should pay attention to causing the basic cause of disease of the arrhythmia at first, analyze type and intensity of the arrhythmia taken place at the same time. It is a functional or organic conclusion accurately not to get unless combining the comprehensive analysis of the clinical materials.
