The present disclosure discloses a device, system and method for testing cardiac exercise functions. Chronotropic Competence Indices (CCIs) are proposed to quantitatively describe the adaptation capability of cardiopulmonary system in response to exercise intensity variation in terms of heart rate changes, and thereby describes the dynamic process of the heart in the body metabolic process. The present disclosure discloses a device which measures the CCIs in real time by using the wearable technology, and referred to as Cardiac Exercise Test (CET). Compared with the Cardiopulmonary Exercise Testing (CPX) and parameters measured by the CPX such as a maximum oxygen uptake, the CCIs have clear clinical meanings and specific normal reference values; and the CET reduces the risk of the test. It is simple to use, and can be used anytime anywhere. It is of great importance in wide clinical applications, and is of great significance in prevention and rehabilitation of cardiopulmonary disease.

Methods and apparatuses, including devices and systems, for remote and detection and/or diagnosis of acute myocardial infarction (AMI). In particular, described herein are handheld devices having an electrode configuration capable of recording three orthogonal ECG lead signals in an orientation-specific manner, and transmitting these signals to a processor. The processor may be remote or local, and it may automatically or semi-automatically detect AMI, atrial fibrillation or other heart disorders based on the analyses of the deviation of the recorded 3 cardiac signals with respect to previously stored baseline recordings.

There is provided a detection apparatus including: a heartbeat sensor that includes a plurality of electrodes and is configured to detect a first detection signal indicating heartbeat of a detection target via the plurality of electrodes; a pulse wave sensor configured to detect a second detection signal indicating a pulse wave of the detection target; and a processing unit configured to detect a pulse of the detection target on the basis of the first detection signal and the second detection signal.

The present invention is related to a cardiovascular monitoring device including an inflatable cuff for surrounding a limb of a user, at least a first and a second electrodes, a controlling circuitry with a processor accommodated in a housing, and a display element. The controlling circuitry is configured to perform a blood pressure measurement through controlling a pressure inside the inflatable cuff, and perform an electrocardiogram measurement by using the electrodes. The processor is also configured to provide a diastolic blood pressure and a systolic blood pressure when the blood pressure measurement is performed, and to provide a heart rhythm information when the electrocardiogram measurement is performed. Further, for achieving a better and more stable contact between the electrodes and the user's skin, the present invention provides an improved structure with electrodes arranged thereon based on the conventional blood pressure monitor.
