Our ECT machines delivers pulsed, bi-derectional square wave stimulus. The current is constant at 0.9 Ampere and the voltage varies automatically by a built in microcomputer as per the impedance of the patient. We conceived and designed the RAJAS keeping three major considerations in mind i.e.
1. Its stimulus parameters had to be chosen on the basis of research data. (Maxwell 1968, Weaver etal 1977 weiner 1980).
2. It should have the capacity to produce seizure virtually 100%.
3. It should be safe and easy to operate.
