• Abstract:

  Atrioventricular blocks (AVB) or atrioventricular (AV) conduction disorders occur when atrial impulses are delayed or fail to reach the ventricles. Total AVB (TAVB) is characterized by the absence of correlation between atrial and ventricular electrical activity, which is translated on the electrocardiogram (ECG) by P waves unrelated to the QRS. It is among the most frequent cardiac arrhythmias, affecting mainly the elderly population. Its treatment depends on the etiology, being performed, in most cases, the definitive pacemaker implantation. Among the various etiologies for the occurrence of AV conduction disorder, we can mention: inflammatory, metabolic/endocrine, drug, hereditary/congenital, infiltrative, neoplastic/traumatic causes, coronary artery disease (CAD), acute myocardial infarction, autoimmune and idiopathic progressive fibrosis, as the most common representative among the degenerative causes. The present work brings a case report of a female patient, 71 years old, hypertensive, type II diabetic, insulin dependent, with chronic CAD and chronic kidney disease and former smoker. On the electrocardiogram (ECG) at rest, on admission he showed AVB. The etiology, clinical manifestations, the importance of diagnosis based on complementary methods, treatment and recommendations are explored, showing resolubility as the main factor in the quality of life of people affected by this disease.
