[Correction of hemodynamics and heart rate disorders in paitients with right coronary artery disease].

PURPOSE OF THE STUDY: To analyze a correlation between sino-atrial node automatic activity and atrio-ventricular conductivity in patients with lower acute myocardial infarction (AMI) and atrio-ventricular blockade II-III (AVB) during infusion therapy.

MATERIALS AND METHODS: Retrospective analysis of care for patients with AMI and AVB was carried out. Infusion therapy effects were studied in 12 patients with right coronary artery disease and AVB.

RESULTS: Infusion therapy in patients with lower acute myocardial infarction, atrio-ventricular blockade and right ventricular failure corrects haemodynamic and dromotropic disturbances. Systolic arterial pressure (SAP) increased to 100,4 mmHg (9,9) after infusion of 400 mLin comparison with SAP after infusion of 200 mL (p = 0.003), Diastolic arterial pressure (DAP) increased to 58,7 mmHg (6,8) in comparison with DAP after infusion of 200 mL (p = 0.011), central venous pressure (CVP) decreased to 12.2 cmH2O (3,7) in comparison with CVP after infusion of 200 mL (p = 0.003). Mode of AVB degree indicator changed t 0O (0;0) (p = 0.028).

CONCLUSIONS: Infusion volume therapy should be used for correction of right ventricular failure and disturbances of atrio-ventricular conductivity in case of right ventricular failure absence.
