A handheld device (100) comprises a plurality of ambulation mechanisms (222-224, 1002-1008) that enable the handheld device (100) to perform translations, rotations or compound movements on a surface (502) on which the device (100) is placed. Using the ambulation mechanisms (222-224, 1002-1008), the device (100) is able to communicate the occurrence of various events to a user via ambulation gestures that are recognized by the user. Ambulation gestures can be programmed by the user. Disclosed ambulation mechanisms (222-224, 1002-1008) comprise linear (302, 700, 800) or rotary (1018, 1102) vibration transducers that are mechanically coupled to elastic feet (226-228, 606-608, 1110) that have an asymmetric tread (402). The asymmetric tread (402) is effective to convert vibration generated by the vibration transducers (302, 700, 800, 1018, 1102) to movement forces tangential to the surface (502) on which the device (100) is placed.

The present invention provides an improved, Internet-based system that seamlessly collects cardiovascular data from a patient before, during, and after a procedure for EP or an ID. During an EP procedure, the system collects information describing the patient's response to PES and the ablation process, ECG waveforms and their various features, HR and other vital signs, HR variability, cardiac arrhythmias, patient demographics, and patient outcomes. Once these data are collected, the system stores them on an Internet-accessible computer system that can deploy a collection of user-selected and custom-developed algorithms. Before and after the procedure, the system also integrates with body-worn and/or programmers that interrogate implanted devices to collect similar data while the patient is either ambulatory, or in a clinic associated with the hospital. A data-collection/storage module, featuring database interface, stores physiological and procedural information measured from the patient.

A determination about whether the subject has sleep apnea will be based in part on the variability of the subject's respirations about the sleep onset time(s).

A method of determining a confidence level in a heart rate obtained from an ECG signal of a patent comprises determining a heart rate from a segment of an ECG signal, the segment having a pre-determined length, and determining a first confidence level in the determined heart rate. If the first confidence level exceeds a predetermined value, the heart rate is output. Otherwise, the method further comprises determining a set of features from the segment of the ECG signal; and classifying the segment of the ECG signal, based on one or more features selected from the determined set of features and the heart rate, into one of at least three classes: noise, an abnormal sinus rhythm and a normal sinus rhythm.
