Abstract: In some embodiments, techniques capable of obtaining high-quality fetal ECG (fECG) information using as few as two composite (maternal and fetal) maternal abdominal ECG (aECG) signals to derive the fetal ECG information are provided. In some embodiments, maternal ECG information and fetal ECG information are both obtained from the aECG signals, and are either presented or stored. The techniques may use novel proposed diffusion-based channel selection criteria. To validate the proposed techniques, analysis results of two publicly available databases are described, and compared with other available techniques in the literature.

Abstract: An example method is performed by an electrocardiogram (ECG) device and includes determining a number of lead wires of an ECG cable assembly that is attached to the ECG device. The method also includes receiving ECG signals using electrodes of the ECG cable assembly. Further, the method includes using the number of lead wires as a basis for selecting a live-lead view from among a first live-lead view and a second live-lead view. Still further, the method includes displaying a representation of the ECG signals in the selected live-lead view in accordance with the selection.

Abstract: A method for monitoring specific activity parameters of the human heart, where ECG and PCG signal monitoring is performed simultaneously by at least two electrodes placed on the chest in such a way that the ECG signal is utilized as a reference time point during PCG monitoring, and monitoring is performed with a measuring unit consisting of a couple of measuring heads containing combined ECG and PCG electrodes, a controlling master measuring head and a slave measuring head performing synchronized implementation, and a computing evaluating unit which is in wireless data communication connection with the above unit and is capable of data processing. ECG and PCG signals are simultaneously monitored by two measuring heads, each comprising an ECG electrode and a PCG electrode, one of the measuring heads serving as a master measuring head and the other one of the measuring heads serving as a slave measuring head.

Abstract: A catheter has a distal assembly with at least one loop with ring electrodes. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and a U-shape bend therebetween. The U-shape bend is anchored at a distal end of a deflectable section which is reinforced by at least one washer having at least two holes, each hole axially aligned with a respective lumen in the deflectable section. Each hole is centered with a lumen so that each puller wire portion therethrough is straight and subjected to tensile force only. A proximal end of the support member is flattened and serrated to provide a better bonding to the distal end of the deflectable section.
