Effect of deep inspiration and expiration on (QT and JT dispersion)‎ in normal subjects

الملخص EN

This study was carried out on 20 normal healthy male volunteers, aged 18-36 years to study QT- dispersion and JT- dispersion in responses to control ,deep inspiration and deep expiration by using non-invasive technique Electrocardiography for measurement of QT- dispersion and JT- dispersion studying the QT- dispersion and JT-dispersion Shows : There are no significant changes in QT-dispersion between control and deep inspiration and also no significant changes between control and deep expiration.

The JT-dispersion shows no significant difference between control and deep inspiration but there is significant increase in JT-dispersion in deep expiration in comparison with the control expiration.On comparison between deep inspiration and deep expiration, there are no significant difference in both QT-Dispersion and JT-Dispersion.
