There are limited number of studies evaluating right ventricular functions in patients with essential hypertension. Standard echocardiographic parameters have been used in all those studies, and data on effects of left ventricular hypertrophy (LVH) on right ventricular functions are lacking. This paper seeks the effect of LVH on the right ventricular functions with standard echocardiography (echo) and pulsed wave tissue Doppler imaging (TDI) in 114 patients with essential hypertension. Findings were compared to 34 healthy subjects who had no systemic disease and negative exercise test, according to the Bruce protocol (group 1). Patients were classified as no LVH in electrocardiography (ECG) and echo (group-2), LVH by echo but not by ECG (group-3) and those who had LVH both by ECG and echo (group-4). None of the standard echocardiographic parameters could detect an abnormality in right vetricular functions due to LVH. However; right ventricular TDI parameters of IVRa speed and Ea deceleration time were higher than in patients with LVH. IVRa speed data collected in right ventricular myocardium (group 4) were greater than in other groups (p 0.01, 0.02 and <0,001, respectively). The Ea deceleration time in group 4 was also prolonged compared to the healthy group and essential hypertensie group which had no LVH (P:0.020 and p:0.037). Assuming these changes reflect right ventricular diastolic disfunction, following results can be concluded: right ventricular functions were influenced by left ventricular hypertrophy and these changes could not be detected by standard echo parameters, and thus it is concluded that LVH in ECG indicates right ventricular diastolic dysfunction.
