1. A system comprising:
- a pulse generator configured to generate an electrical stimulation;
an electrode configured to deliver the electrical stimulation to a tissue in a patient;
a sensor configured to detect a response of the tissue to the electrical stimulation; and
a processor configured to determine a concentration of potassium ions in extracellular fluid of the patient as a function of the response.

Abstract
In general, the invention is directed to methods and devices for determining a potassium ion concentration in the extracellular fluid of a patient. A system includes an electrode deployed in or near a tissue, such as a skeletal muscle, of the patient. A pulse generator supplies one or more stimulations to the tissue, and a sensor, such as an accelerometer, detects the response of the tissue to the stimulations. A processor determines a concentration of potassium ions in the extracellular fluid as a function of the response.
