Abstract

The purpose of this study was to investigate the influence of electrical stimulation transmitted through the body during electroconvulsive therapy on traditional and relatively new ventricular repolarization parameters (Rate corrected QT interval (QTc), QT dispersion (QTd), rate corrected JT interval (JTc), JT dispersion (JTd), T-peak to T-end interval (Tp-e) and Tp-e/QTc ratio) under propofol anaesthesia. Twenty-two patients (aged 18-50 years) who were each scheduled for ECT for major depression, bipolar disorder or schizophrenia enrolled to the study. Electrocardiography (ECG) recordings were obtained before anaesthesia and within 3-5 min after electrical stimulus of ECT for measurements. QTc, QTd, JTc, JTd, Tp-e and Tp-e/QTc were measured as repolarization indices. The study included twenty-two patients, 9(40.9%) females and 13(59.1%) males, and the mean age accounted for 33.57 ± 9.95 years. The comparison of the measured parameters before and after ECT, which were not statistically different, were as follows: QTc (416.52 ± 46.64 vs 430.00 ± 34.00msn; p = 0.18), JTc (308.09 ± 25.09 vs 315.47 ± 26.89msn; p = 0.30), QTd (22.27 ± 11.51 vs 20.45 ± 9.9msn; p = 0.52) and JTd (22.72 ± 11.2 vs 17.72 ± 10.20msn; p = 0.06). Also, no s...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Bipolar Disorder

Bipolar disorder is characterized by manic and/or depressive episodes and associated with uncommon shifts in mood, activity levels, and energy. Discover the latest research this illness here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
