Abstract
An ECT system capable of focusing the electrical signals on a specific portion of the patient's brain is provided. The ECT system includes a means of applying unidirectional electrical signals and asymmetric electrodes for focusing the signals on the patient. A method of titrating an electro-convulsive therapy (ECT) system and a method of operating an ECT system are also provided. The method includes setting an initial current value, administering an ECT signal to the patient, determining if the seizure threshold has been achieved, and repeating as necessary until the seizure threshold is achieved.
Claims11
A method of titrating an electro-convulsive therapy (ECT) system, the method comprising:
- setting an initial current value on the ECT system to less than 800 mA;
- administering an electrical signal to the patient, the electrical signal comprising the initial current value;
- determining if a seizure threshold has been achieved;
- and
- if the seizure threshold has not been achieved, sequentially raising a current value of the electrical signal, administering the electrical signal to the patient, and determining if the seizure threshold has been achieved until the seizure threshold is achieved.
A method of operating an electro-convulsive therapy (ECT) system, the method comprising:
- applying a first electrode and a second electrode to a patient;
- performing a titration process to determine a seizure threshold for the patient, the titration process including:
- setting an initial current value on the ECT system to less than 800 mA,
- administering an electrical signal to the patient, the electrical signal comprising the initial current value,
- determining if the seizure threshold has been achieved, and
- if the seizure threshold has not been achieved, sequentially raising a current value of the electrical signal, administering the electrical signal to the patient, and determining if the seizure threshold has been achieved until the seizure threshold is achieved;
- setting parameters of the ECT system based on the seizure threshold;
- and
- administering an ECT signal to the patient.
