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: An example method of analyzing electrocardiogram (ECG) signals includes receiving, at an ECG device, ECG signals from a multi-lead ECG system. The multi-lead ECG system includes multiple electrodes and leads, and each lead of the multi-lead ECG system provides one of the ECG signals and is coupled to more than one of the multiple electrodes, where certain electrodes are coupled to more than one lead. The method also includes detecting artifact in one or more of the ECG signals, classifying the artifact as a type of artifact, determining which leads of the multiple leads contain at least a threshold amount of the type of artifact, for the leads of the multiple leads that contain at least the threshold amount of the type of artifact identifying a common electrode to the leads, and generating a notification by the ECG device indicating that the common electrode is sensing the artifact.

Abstract: The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received, derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. In some embodiments, a penalty value can be determined for at least one of the pauses, from at least one control factor unrelated to a constant linear dependence on the pause duration. An indicative value can be derived from the penalty value. In some embodiments, at least some of the pauses are classified in one or more pause groups, depending on how well they meet one or more classification criteria. The indicative value can be derived for one of the pause groups. The indicative value can be output, and/or an alarm can be emitted if it exceeds a threshold. CPR quality assessment can be improved in real time, and provide feedback for training.

Abstract: The presence of a cardiac pulse in a patient is determined by evaluating fluctuations in an electrical signal that represents a measurement of the patient's transthoracic impedance. Impedance signal data obtained from the patient is analyzed for a feature indicative of the presence of a cardiac pulse. Whether a cardiac pulse is present in the patient is determined based on the feature in the impedance signal data. Electrocardiogram (ECG) data may also be obtained in time coordination with the impedance signal data. Various applications for the pulse detection of the invention include detection of PEA and prompting PEA-specific therapy, prompting defibrillation therapy and/or CPR, and prompting rescue breathing depending on detection of respiration.
