Electrocardiograph (ECG) is a tracing, which represents the heart electrical activity derived by amplifying minutely small electrical impulses generated by the heart. The electrical impulses generated in the heart muscle are recorded and transmitted to the electrocardiograph by electrodes or leads attached to the body by small disposable metal plates. The moistened plates are attached to the arms, legs, and cardiac areas. ECG is a widely accepted and important diagnostic tool. ECG is used in some routine medical examinations when a heart disorder is present or suspected. ECG helps diagnose the damage that may have been inflicted on the heart muscle as a result of coronary occlusion, rheumatic fever, the presence of abnormal rhythms, and the effect of drugs. Moreover, ECG recordings provide information on the current fitness status of the heart as well as reflect HRV as a result of ANS regulatory balance.

Photoplethysmographs (PPGs)

Photoplethysmograph (PPG) was developed in the 1960's and 1970's by psychophysiology researchers. The instrument is used for assessment of peripheral blood flow to the extremities. When the client is stressed their blood vessels constrict (less blood flow in fingers). Photoplethysmograph is based upon the premise that all living tissue and blood have different light-absorbing properties. PPG works by placing an individual finger between two parts of a transducer consisting of a light source and a photocell (which converts light to electrical energy). A beam of infrared light is projected toward the photocell. The blood in the finger scatters light in the infrared range, and the amount of light reaching the cell is inversely related to the amount of blood in the finger. Hence, when blood vessels in the finger dilate, the increased blood flow allows less light to reach the photocell, when blood vessels constrict, blood flow is decreased and increased light reaches the photocell. Pulse volume measurements are related beat-to-beat variations in the force of blood flow. Phasic changes made on a beat-to-beat basis, are called pulse volume measurements and are related to beat variations in the force of blood flow. These beat-to-beat changes in peripheral blood flow reflect ANS regulatory activity and can be used for the purpose of evaluation of sympathetic activity or stress. (“Measuring Stress” by S. Cohen, R. Kessler and L. U. Gordon, 1995)

Using device right

Biocom 4000 ECG recorder has three large non-disposable dry ECG electrodes to be placed on wrists of both hands secured with elastic wristbands.
Using bluetooth PPG Typically the PPG BC-2000 should be placed on earlobe.

In some cases when earlobe placement does not give good pulse wave signal the PPG BC-2000 can be placed on a finger.
The PPG BC-1000 is designed for use on finger tip
Typically the PPG HRM-02 should be placed on earlobe

In some cases when earlobe placement does not give good pulse wave signal the ear-clip can be placed on a finger.
