This relates to a monitoring system capable of measuring a plurality of vital signs. The monitoring system can include a plurality of sensors including, but not limited to, electrodes, piezoelectric sensors, temperature sensors, and accelerometers. The monitoring system can be capable of operating in one or more operation modes such as, for example: capacitance measurement mode, electrical measurement mode, piezoelectric measurement mode, temperature measurement mode, acceleration measurement mode, impedance measurement mode, and standby mode. Based on the measured values, the monitoring system can analyze the user's sleep, provide feedback and suggestions to the user, and/or can adjust or control the environmental conditions to improve the user's sleep. The monitoring system can further be capable of analyzing the sleep of the user(s) without directly contacting or attaching uncomfortable probes to the user(s) and without having to analyze the sleep in an unknown environment (e.g., a medical facility).

An ECG device may include a housing, a plurality of leads coupled with the housing, and couplers configured to attach the leads to electrodes. A marking switch may be coupled with the housing. The ECG device may be configured to monitor cardiac-related activity and record related data. The marking switch may be configured to record a heart-related event when engaged by a user. User interfaces on one or more computing devices may allow a clinician and/or a patient to view information related to the ECG device and its recorded data, as well as to facilitate communication between the ECG device and one or more servers and to associate symptoms with heart-related events. ECG systems include the ECG device and the one or more servers. ECG methods involve using the ECG device and ECG system in recording and storing heart-related data and allowing clinicians access to retrieve it for analysis.

Methods and systems for combining ablation therapy with navigation of the ablation device. An ablation system may be configured for use with one of two methods to prevent loss of navigation signals during ablation energy delivery. In the first method, ablation energy signals are filtered from the navigation signal. In the second method, the delivery of ablation energy is sequenced with the delivery of navigation energy such that ablation energy and navigation energy are not delivered at the same time and navigation signals received by the system are time-division multiplexed to reconstruct the navigation signals and determine a location of the device within the patient.
