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 as well as effect of systole and diastole cycle variation on heart beat rate 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.

An electrocardiogram may detect ventricular ectopic beats. For frequent abnormal...

    There is an intense search for positive inotropic strategies. It is well known that the interbeat duration is a critical determinant of cardiac contractility. Generally, when frequency increases, so does contractile strength. We hypothesize that the beat-to-beat variability at a given heart rate...
