individuals in this arm used Snap according to the instruction on time and screened at the symptomatic

patients in the RC arm accepted normal methods

screen, transmission, and analysis ECG automated

Participants in Snap group acquired ECG once od according to the rules and transmitted ECG immediately once symptom appeared between 3-month. Patients in the routine treatment (RT) group were administrated normal diagnostic techniques. At 3-month, compared the incidence atrial arrhythmia(atrial premature beats and atrial tachycardia) and ventricula arrhythmia(ventricular premature beats and ventricular tachycardia) between two groups.

Using RAND 36-Item Short Form Health Survey (SF-36) 1.0 Questionnaire items assessed the quality of life of participants. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. To calculate the scores it is necessary to purchase special software. Pricing depends on the number of scores that the researcher needs to calculate.

The eight sections are: vitality, physical functioning, bodily pain, general, health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health. The total scale ranges from 35 to 145. The higher the total score, the better the patient's quality of life.
