Study to Evaluate the Performance of CardiacSense PPG Sensor
Condition: Atrial Fibrillation
MeSH terms: Atrial Fibrillation
Study type: Interventional

Summary: 
      study to evaluate the performance of the CardiacSense1's embedded PPG under different
      environmental and physical conditions
    

Detailed description: 
      The clinical study is a Prospective, Open, Single-Center, and Controlled Study to Evaluate
      the Performance of a PPG sensor in the CardiacSense1 device.

      The CardiacSense1 is a wrist worn device designed to detect atrial fibrillation (AF). The AF
      detection of the device is based on a portable photoplethysmograph (PPG) sensor that is
      designed for continuous heart rate monitoring. The photoplethysmograph is a noninvasive
      circulatory signal related to the pulsatile volume of blood in the tissue.

      Twenty (20) subjects (female and male) that do not suffer from atrial defibrillation and
      additional four (4) patients who are diagnosed as suffering from atrial fibrillation will be
      enrolled to the study.

      Comparison of CardiacSense1 PPG individual peak detection to the corresponding recorded
      activity of an FDA-cleared ECG Holter, on a beat-by-beat basis will be performed on the
      following conditions:

      All subjects will be exposed to 45 minutes of indoor standard office fluorescent light and 45
      minutes to outdoor sunlight during mid-day. In addition, Subjects will be asked to walk for 1
      minute once every 10 minutes and will be exposed to an indoor environment of 22±3 - 28±3
      degree Celsius for 45 minutes and outdoor temperature of at least 15 degree Celsius, on the
      other 45 minutes.

      4 Subjects will be tested in the following conditions: driving a car for 30 minutes; High
      wrist hair density subjects; Two subjects 65 y/o or older, two subjects 30 y/o or younger;
      Two subjects with BMI below 18.5 (underweight) and two subjects with BMI over 30 (Obesity);
      Two subjects with skin type 6 (Fitzpatrick) and two subjects with skin type 5; Four subjects
      with diagnosed persistent atrial fibrillation.

Intervention description(s): Subjects were fitted with One lead Holter monitor and the CardiacSense1 watch simultaneously and were tested in the following condition:
Sitting down for 10 minutes, walking for one minute and repeat this sequence twice at Indoor 28 ±3 degree Celsius.
Sitting down for 10 minutes, walking for one minute and repeat this sequence twice at Indoor 22 ±3 degree Celsius.
Sitting down for 10 minutes,outdoor walking for one minute and repeat this sequence four times At the end the devices were removed from the subject by the medical staff.The recorded data was downloaded for analysis by the Sponsor; Subjects were fitted with One lead Holter monitor and the CardiacSense1 watch simultaneously and were tested in the following condition:
