Objective: To study autonomic imbalance if any in normal tension glaucoma (NTG)patients by heart rate variability (HRV)and head-up tilt (HUT)test.Methods: The study subjects of age between 45 and 65 years of either sex comprised 20 patients with NTG (Group ІІ)and 20 age- and sex-matched healthy controls (Group І). Different variables of time and frequency domain of HRV were analyzed at rest, during HUT and the recovery period.Results: Highly significant decrease in value of root mean square successive difference observed in Group ІІ (p<0.000)in comparison to controls. The high-frequency variables (HF [nu]and HF [ms2])were significantly less (p<0.000)and low frequency (LF)/HF ratio was significantly high (p<0.000) in Group ІІ.Conclusion: During stress test, i.e., HUT there was the greater withdrawal of parasympathetic input to heart; hence, there was relatively oversympathetic activity due to sympatho-vagal imbalance.Keywords: Stress test, Sympatho-vagal imbalance, Autonomic function test.

The Right

We present a patient with a primitive neuroectodermal tumor arising from the right atrium who experienced multiple syncope episodes daily, which had first appeared 1 month after surgery. The symptoms continued to worsen over the course of chemotherapy, and the autonomic function test (AFT) was performed after the 14th chemotherapy cycle. The AFT revealed orthostatic hypotension and reduced baroreflex-dependent sympathetic reactivity. Physical counterpressure techniques were applied with a visual biofeedback intervention, and were found to be effective in reducing the syncope episodes.
