Abstract:
A method of monitoring a health status of a patient using a monitoring system comprising a pair of finger ring electrocardiogram (ECG) monitors. Each finger ring monitor comprises an inner ring member and an outer ring member positioned radially outward from and operably connected to the inner ring member. The inner ring member of each monitor features a conductor characterized by at least one physiological-type sensor, and an annular bladder that defines an adjustable aperture sized to receive a left-hand finger of a patient and a right-hand finger of the patient, respectively. Upon triggering by positioning the pair of finger ring ECG monitors substantially together, the conductors of each of the finger ring ECG monitors are configured to receive biopotential signals from skin on the fingers of the patient.
Abstract:
A physiological signal monitor having retractable wires may include a housing, a patch and a cradle. The housing may be adapted to carry a memory, a first electrical contact, a second electrical contact, and a processor in data communication with the memory. The patch may include a first side adapted to be secured to a patient and an opposing second side. The cradle connects to the second side of the patch and may be adapted to carry the housing. The cradle may include a wire retractor, a first electrical pad adapted to contact the first electrical contact, a second electrical pad adapted to contact the second electrical contact, a first sensing connector, a second sensing connector, a first wire connecting the first electrical pad to the first sensing connector, and a second wire connecting the second electrical pad to the second sensing connector.
Abstract:
A method of detecting atrial fibrillation (AFib) includes receiving electrical signals representative of a beating heart and measuring atrial activity over a time window of three or more beats. The method may also include measuring beat interval variation over the time window and combining the measures of atrial activity and beat interval variation to produce an indication of an atrial fibrillation condition in the electrical signal. The method may further include producing the indication with a processing system. Measuring atrial activity may include measuring P waves, and measuring P waves may include analyzing a standard deviation of a PR interval.
Abstract:
A retractable multi-use cardiac monitor is provided that includes a memory, and first and second sensing connectors positioned on outsides of first and second housings, respectively. The first and second sensing connectors are configured to detect electrocardiogram (ECG) signals that are stored onto the memory as ECG data. The second housing of the retractable multi-use cardiac monitor also includes a wire retractor configured to extend and retract a wire that connects the second and first housings, and that defines an interelectrode distance between the first and second sensing connectors. The retractable multi-use cardiac monitor further includes systems and methods for determining a length for the interelectrode distance that is optimum in terms of strength and fidelity of the detected ECG signals. The retractable multi-use cardiac monitor further includes a wireless radio configured to transmit a portion of the stored ECG data from the memory to a destination.
