[Isolated infarction of the right ventricle caused by occlusion of the non-dominant right coronary artery. Role of sequential atrioventricular stimulation].
OBJECTIVE
Description of a case report.


METHODS
The case of a 66-year old woman with cardiogenic shock due to isolated acute right ventricular infarction caused by occlusion of a diminutive right coronary artery is described.


RESULTS
Her ECG showed the presence of junctional rhythm and ST elevation in V1-V2 and right precordial leads. Despite infusion of plasma expanders, atropine and inotropic agents, clinical conditions did not improve, but success was only achieved by means of atrioventricular (AV) sequential pacing which allowed good hemodynamic stabilization of the patient.


CONCLUSIONS
It is noteworthy that occlusion even of a diminutive right coronary artery can induce cardiogenic shock, and that restoration of the physiological AV synchrony--although somewhat impaired by prolonged atrial stunning--has a markedly positive effect on the hemodynamic balance.
