ECT Parameters, According to Treatment Group.^*

PARAMETER	Ultrabrief Pulse Right Unilateral ECT (N = 22)	Ultrabrief Pulse Bilateral ECT (N = 23)	Brief Pulse Right Unilateral ECT (N = 22)	Brief Pulse Bilateral ECT (N = 23)
Atropine (mg)^†	0.4±0.0	0.4±0.0	0.4±0.0	0.4±0.0
Methohexital (mg)^†	80±9	88±9	74±9	81±9
Succinylcholine (mg)^†	58±3	59±3	54±3	58±3
Initial seizure threshold (mC)	22±8^a	59±49^b	70±27^b	162±151^c
Charge to induce seizure (mC)^†	103±38^a	165±144^a	318±123^b	285±157^b
Motor seizure duration (sec)^†	40±10	43±9	40±9	46±17
EEG seizure duration (sec)^†	50±14	55±15	53±18	60±26

Plus-minus values are means±SD. mC denotes millicoulombs or charge. ANCOVA indicated that there significant differences among the treatment groups for parameters superscript letters attached to each value. Values with different letter superscripts differed significantly from each other in post hoc t-tests on least-squares adjusted means (P<0.05).
