Systems and methods for electrocardiographic waveform analysis, data presentation and actionable alert generation are described. Electrocardiographic waveform data can be received from a wearable device associated with a patient. A mathematical analysis of at least a portion of the electrocardiographic waveform data can be performed to provide cardiac analytics. In instances where (1) a pathologically prolonged QT interval and (2) an R on T premature ventricular contraction and/or a ventricular tachycardia are detected from the cardiac analytics of the at least a portion of the electrocardiographic waveform data, an actionable alert can be generated and displayed with a visualization of the cardiac analytics.

A patient side cart for a teleoperated surgical system may comprise a column extending from a base, the column having a first end connected to the base and a second end opposite the first end. The patient side cart may further include a surgical instrument manipulator arm coupled proximate the second end of the column, and an obstacle indication system comprising an illumination source mounted on the patient side cart at a height above a location the surgical instrument manipulator arm is coupled to the second end of the column, the height being measured in a direction the column extends from the base.

Systems, interfaces, and methods are described herein related to the evaluation of a patient's cardiac conduction system and evaluation of cardiac conduction system pacing therapy being delivered to the patient's cardiac conduction system. Evaluation of the patient's cardiac conduction system may utilize a plurality of breakthrough maps to determine where a cardiac conduction system block may be located. Evaluation of cardiac conduction system pacing therapy may utilize various electrical heterogeneity information monitored before and during delivery of cardiac conduction system pacing therapy.

A medical device processor is configured to receive a first cardiac electrical signal sensed from a first sensing electrode vector, receive a second cardiac electrical signal sensed from a second sensing electrode vector different than the first sensing electrode vector, and construct a third cardiac electrical signal from the first cardiac electrical signal and the second cardiac electrical signal. In some examples, the system determines sensed cardiac events according to at least one setting of a cardiac event sensing threshold control parameter from at least the third cardiac electrical signal and may determine at least one acceptable setting of a sensing control parameter based on the determined sensed cardiac events. The processor may generate an output representative of the determined sensed cardiac events.

A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.

Techniques are disclosed for segmenting electrocardiogram (ECG) signals. In one example, a method to segment an electrocardiogram (ECG) signal may include detecting consecutive heartbeats in an ECG signal. The method also includes segmenting the ECG signal into multiple ECG segments surrounding the detected consecutive heartbeats and generating an ECG data set by joining consecutive ECG segments. The generated the ECG data set represents the detected heartbeats. In some such examples, each ECG segment is of a duration to include a QRS complex, a P wave, and a T wave.

A muscle imaging system that uses an ultrasound probe to image one or more muscles of a subject. A processing unit controls a driving mechanism to set a position of the ultrasound probe with respect to the subject. A position of the ultrasound probe, during an imaging process, is at least partly based upon a shape of the subject detected by a shape sensor.

A method is described herein comprising receiving accelerometer data from an accelerometer, wherein the accelerometer measures an activity level of an animal, wherein a device worn by the animal includes the accelerometer. The method includes receiving a heart rate of the animal from a heart rate monitor, wherein the device includes the heart rate monitor. The method includes receiving ambient temperature of the animal from an ambient temperature sensor, wherein the device includes the ambient temperature sensor. The method includes assessing a health condition of the animal by using the ambient temperature, the heart rate, and the accelerometer data.

A health alert device includes a physiological sensor and processing circuitry. The physiological sensor captures physiological data, including heart rate and blood oxygen data, of a detainee. The processing circuitry repeatedly receives the physiological data, calculates a health metric parameter based on a combination of the physiological data, determines a health metric baseline based on a series of health metric parameters determined over a baseline determination duration, determines first and second risk alert thresholds based on the health metric baseline, determines a health metric delta based on newly received physiological data and the health metric baseline, and transmits first and second risk alert communications to an alert device to cause the alert device to display first and second risk alerts on an alert device display in response to the health metric delta exceeding the first and second risk alert thresholds, respectively.

Embodiments of the present invention provide a novel and non-obvious method, system and computer program product for the selfie image sourced diagnosis of prospective eye disease. In an embodiment of the invention, a method for diagnosing prospective eye disease includes acquiring a selfie image with a portable communications device, recognizing a portion of the selfie image as an eye and comparing the portion of the selfie image to a pre-stored image of the eye in order to detect a threshold change from the pre-stored image to the selfie image. Thereafter, in response to detecting the threshold change, an alert is displayed in a display of the portable communications device. In this regard, optionally, the threshold change can be classified, and the classification correlated to a prospective ophthalmological diagnosis through the use of a classification table. Then, the prospective ophthalmological diagnosis can be included in the alert.
