's general knowledge of atrio-ventricular block for a time
Disease is summed up:
Atrio-ventricular block (first degree atrioventricular block, degree AVB) for a time Mean the room room conducts time to lengthen, exceed the normal range, but each atrium is excited can still spread into the ventricle, also claim the room room conducts the delay.
The physical sign of symptom:
Atrio-ventricular block does not cause obvious symptom and physical sign for a time. In myocarditis or patient's auscultation of other heart disease, can find the first loud heart sound was lightened while blocking suddenly. Clinical manifestation, more in order to send symptom or physical sign of disease originally.
Healing solution:
Atrio-ventricular block does not usually produce dynamics of blood flow to change for a time, to having no symptom, not also having hypotension or sinus the slow one aroused in interest that does not need special-purpose processing, directed primarily to having illness coming on originallying because treat; The more slowly persons who have obvious symptoms can use atropine 0.3mg to the heart rate, take orally 2- 3 times d; Or aminophylline 100- 200mg, take orally 2- 3 times d. Some teenagers appear issue lengthen among the P-R, have obvious symptom, one return to normal among the P-R after the treatment through resist rheumatism, should consider as due to rheumatic fever. Atrio-ventricular block have patient of symptom for a time to lie in wish in the system Pu, must follow up a case by regular visits to and observe closely, because it may have changed into the atrio-ventricular block of two degrees of Model 2 suddenly, even highly change into or atrio-ventricular block of three degrees. Medical history that if the patient fainted to break out and getting rid of other reasons. Though only for a time atrio-ventricular block, wish one bunch of electric pictures verifies that wishes one bunch of one that lefts was blocked for a time in bunch or wishes on the electrocardiogram, must consider placing the pace maker treatment. As the patient has history of fainting, one among the electrocardiograms P-R is normal, but wish one bunch of electric charts is a prominent extension (> 60ms) among H-V now ,Also should consider placing the pace maker.
