A heart activity measurement device for an individual including: a processing unit; at least one measurement cable, including a first end suited for connection to the processing unit in order to form an input for an electrical potential, and a second end; a support, ready for an individual to wear, where the support supports the cable so as to keep a predefined path for the cable relative to the skin of the individual when the support is worn. The cable is laid out such that when the support is worn, any contact between an electrically conducting part of the cable and the skin of the individual is prevented. The second end of the cable does not have any electrode for contact with the skin. The support is further laid out for keeping a predefined spacing between a measurement portion of the cable and the skin of the individual.

An assembly for enabling a caregiver to secure a physiological monitoring device to an arm of a user can include the physiological monitoring device a cradle configured to removably secure to the physiological monitoring device and to the user's arm. The physiological monitoring device can include a first connector port configured to electrically connect to a first cable and a first locking tab movable between an extended position and a retracted position.

Systems, methods, and interfaces are described herein for noninvasively determining an optimal coronary sinus branch to cannulate for a medical electrical lead. One exemplary method involves applying an electrode apparatus having a plurality of electrodes to a torso of a patient. One of a right ventricular (RV) lead is introduced to a right ventricle or a right atrial (RA) lead is introduced to a right atrium. Noninvasively ultrasonic energy is introduced to a target tissue selected from a set of target tissues. In response to delivering ultrasonic energy to the cardiac tissue, a processing unit receives a torso-surface potential signal from each of a plurality of electrodes distributed on a torso of a patient for the target tissue. Signals are sensed from one of the RA lead and the RV lead in response to delivering ultrasonic energy. For at least a subset of the plurality of electrodes, calculating, with the processing unit, a torso-surface activation time based on the signal sensed from the electrode. Determining whether the tissue site or the another tissue site provides optimal cardiac resynchronization.

A lightweight, disposable and substantially radiolucent electrode or sensor assembly for that universally connects to separate, non-integrated electrodes or sensors for the monitoring of the physiological parameters of a live subject wherein the electrode assembly is comprised of one or more radiolucent electrical connectors for connecting the electrode assembly to the sensors. The present invention also discloses a method of positioning the electrode assembly on a patient whose physiological signs are being monitored such that access to the patient's chest is substantially unimpeded so as not to obstruct the electromagnetic imaging of the patient's chest, the application of defibrillation paddles or surgical procedures that require access to the chest area.
