Right ventricular tissue doppler time intervals in congestive heart failure

Purpose: The purpose of our research was to study the changes in right ventricular (RV) TDI parameters in patients with Left Ventricular Heart Failure (HF). Material and methods: We studied 52 patients with II-IV NYHA functional class HF (I gr.) and 110 patients with Arterial Hypertension and Coronary Artery Disease but without HF. RV TDI was registered from lateral corner of tricuspid valve. In HF group 22 patients had systolic and 30 – diastolic HF. All patients where in sinus rhythm. We measured maximal systolic (S2), isometric contraction (S1), early diastolic (E) and late diastolic (A) velocities; ejection…
