A system includes a catheter and a processor. The catheter includes a distal-end assembly coupled to a distal end of a shaft for insertion into a cavity of an organ of a patient, the distal-end assembly including (i) one or more functional electrodes configured to be placed in contact with wall tissue of the cavity and (ii) a reference electrode configured to be placed in the cavity but not in contact with the wall tissue. The processor is configured to (i) estimate one or more impedances between one or more of the functional electrodes and the reference electrode, and (ii) based on the impedances, determine, for at least a functional electrode from among the one or more functional electrodes, whether the functional electrode is in physical contact with the wall tissue.

A wearable apparatus capable of altering a physiological parameter such as the heart rate of a user to provide a relaxing or stimulating effect on the user is provided. The apparatus comprises a device capable of engaging the patient's skin to provide a rhythmic tactile stimulus to the user that can alter the user's heart rate and an arrangement for securing the device to the user such that the device can apply the stimulus to the user. The apparatus may be part of a system enabling the device to be controlled remotely. The apparatus may also be configured to provide additional tactile stimuli.

One variation of a method for delivering a digital medicine experience to a user includes: loading the digital medicine experience at a sensory immersion vessel; calculating a target value of a bioindicator of the physiological state of the user, the target value of the bioindicator corresponding to a target physiological state of the user; at an initial time, rendering sensory representations of a set of elements in a multi-sensory virtual environment within the sensory immersion vessel at an initial progression rate; at a time during the digital medicine experience, succeeding the initial time, measuring a value of the bioindicator; calculating a progression rate through the digital medicine experience based on a difference between the value of the bioindicator and the target value of the bioindicator; and at a second time succeeding the time, rendering sensory representations of the set of elements in the multi-sensory virtual environment at the progression rate.
