Electroconvulsive Therapy (ECT) is used to treat several mental illnesses. Seizure duration is used to determine if the administered stimulus was adequate. Duration is estimated by Electroencephalogram (EEG) interpretation and/or observing motor response. Neither method is universally accepted, nor considered the gold standard; hence both are employed. This study investigated the relationship between the methods. The hypothesis tested was that they would have a strong positive correlation. Previous research suggested that the two methods didn’t result in the same estimate. A case series was carried out using recorded estimates prospectively obtained from 102 ECT procedures on adult Psychiatric inpatients. A strong, consistent, predictable relationship between the methods was not identified. However; using 15 seconds as the minimum for an adequate seizure response, there was agreement in 77% of the cases. In conclusion, this research has demonstrated that while the two methods differ, similar clinical results can be obtained by applying a limiter to both measures.
