Objective: The objectives of this study were to determine the prevalence of Atrioventricular Blocks (AVB) at the Center Hospitalize ET Universities de Conakry but also to describe the clinical signs, the paraclinical signs and the management of AVB.

Patients and methods: We carried out a prospective multicenter descriptive type study lasting 6 months from April 20 to October 20, 2021. All patients received an electrocardiogram and/or a Holter ECG.

Results: We identified 64 cases of AVB including 56.3% complete atrioventricular block, 20.3% 2^nd degree AVB Mobitz I, (17.2%) AVB Mobitz II, and 6.2% high degree AVB. AVBs were more common in men (56%) versus 44% in women. Symptoms were dominated by dyspnea (60.5%), syncope (46.1%) and physical asthenia (30.8%). The average heart rate was 48.3 bpm (range 26 and 98 bpm). The AVBs were mainly of degenerative (68.7%), idiopathic (18.7%) and ischemic (6.2%) origin. The indication of stimulation was asked in 43 patients. The locations were carried out in Dakar (9 squares), Tunisia (4 squares) and in Guinea (1 square) with respective average costs of €5,000, €7,700 and €5,000. The mode of stimulation, the most used was the double chamber (DDD, DDIR) which represents 78% of the cases against 21.4% for the monochamber (VVI, VVIR).

Conclusion: Pacing is a major challenge in Guinea. State support in staff training, the opening of a cardiac catheterization center and the acquisition of pacemakers could considerably improve patient care.
