An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECG is also used to measure the rate and regularity of heart beats and can be correlated to blood pressure measurement. This paper describes a technique of the determination of systole and diastole cycle duration from the RR-cycle using speech parameters. The formant F2 and F3 characterize different emotional states like anger and fear. One heart beat includes one systole and one diastole cycle. In an electrocardiogram, electrical systole of the ventricles begins at the beginning of the QRS complex. Diastolic variation occurs after the systole cycle. RT interval describes systole cycle duration. The ECG, and the speech sample of several informants have been recorded simultaneously to obtain the required relationship.
