System and method for determining a probability for a person to have arrhythmia

#The present disclosure relates generally to determination of a medical condition; and more specifically, to a system and a method for determining probability of arrhythmia for a person.

#Conventionally, issues such as hypertension, diabetes, obesity, poor diet, excessive alcohol intake and so forth are known to cause health conditions in people. Such health conditions may include narrowing, deformation and clotting of blood vessels, further leading to diseases such as cardiovascular and cerebrovascular diseases. A cerebrovascular disease is a disease that affects the blood vessels that supply blood to the brain. Such diseases may include a cerebrovascular accident (CVA or stroke), which is one of the leading causes of fatality and disability in people around the world. Stroke generally occurs due to insufficient blood supply to the brain, causing a supply of oxygen and nutrients to the brain to be limited or stopped, which may lead to death of brain cells.

#Strokes may include ischemic strokes that are caused by a blood clot blocking blood supply to the brain and hemorrhagic strokes that are caused by a blood vessel supplying blood to the brain to be ruptured, preventing blood flow to the brain. Further, causes of ischemic strokes include blockage of blood supply by debris originating elsewhere in the body, usually in the heart (an embolic stroke), blockage of blood supply to the brain due to a blood clot forming in the brain vessels (thrombotic stroke), decrease in blood supply to all parts of the brain (cerebral hypoperfusion) and so forth. Generally about 30% of strokes are embolic strokes (from cardiac origin) and 70% of strokes are ischemic (narrowing of cerebral vessels).

#The summary above, as well as the following detailed description of illustrative embodiments, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the present disclosure, exemplary constructions of the disclosure are shown in the drawings. However, the present disclosure is not limited to specific methods and instrumentalities disclosed herein. Moreover, those in the art will understand that the drawings are not to scale. Wherever possible, like elements have been indicated by identical numbers.

#Embodiments of the present disclosure will now be described, by way of example only, with reference to the following diagrams wherein:

#FIG. 1 is schematic illustration of a system for determining a probability of arrhythmia for a person, in accordance with an embodiment of the present disclosure;

#In the accompanying drawings, an underlined number is employed to represent an item over which the underlined number is positioned or an item to which the underlined number is adjacent. A non-underlined number relates to an item identified by a line linking the non-underlined number to the item. When a number is non-underlined and accompanied by an associated arrow, the non-underlined number is used to identify a general item at which the arrow is pointing.

#The following detailed description illustrates embodiments of the present disclosure and ways in which they can be implemented. Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practicing the present disclosure are also possible.

#In one aspect, an embodiment of the present disclosure provides a system for determining a probability of arrhythmia for a person, comprising a wearable device comprising means for measuring heartbeat interval of the person for a period of time; an accelerometer; means for measuring an electrocardiogram of the person; a user interface for providing information and alerts; and a processor configured to detect a period of rest of the person, based on measurement data from the accelerometer, analyse the measured heartbeat interval to determine a probability of having arrhythmia for the person; generate an alert to the user interface, if the probability exceeds a predetermined threshold value, to alert the person to measure the electrocardiogram with the second means for measuring an electrocardiogram; analyse the measured electrocardiogram to determine if the probable arrhythmia is confirmed; and indicate the confirmed arrhythmia to the person via the user interface.
