“…In these studies, the effectiveness of treatment in ECG measurements was evaluated. 29 – 31 In our results, it was determined that patients with schizophrenia who did not start medical treatments had minimum and maximum values and extended Tp-e dispersion. The Tp-e/QTc ratio is much more reliable than other parameters in showing the ventricular arrhythmia risk.…”

Objective The purpose of this study was to examine electrocardiographic ventricular arrhythmia predictors in patients with schizophrenia by comparing with healthy controls. Methods The study included 100 patients with schizophrenia and 100 healthy controls. Electrocardiography (ECG) was performed on all participants in resting position. T-wave peak to end (Tp-e), QT ranges, P-wave dispersion (Pd), and R-R range were measured. Then, the Schizophrenia Positive and Negative Syndrome Scale (PANSS) and the Calgary Depression Scale for Schizophrenia (CDSS) were applied to the schizophrenia group. Results The PANSS positive symptom subscale was calculated as 10.41 (SD = 2.27), the negative symptom subscale was calculated as 14.44 (SD = 5.42), and the overall functionality level was calculated as 27.04 (SD = 5.43). The mean CDSS score was determined to be 3.74 (SD = 2.15). No differences were detected in the heart rate measurements of the patient and control groups in ECG results ( P = .427). The minimum QT interval and minimum Tp-e wave times were found to be low in the patient group ( P < .001 for both intervals). Corrected QTc dispersion, Pd, Tp-e dispersion, and QT dispersion were found to be higher in the patient group than in healthy controls ( P < .001 for all intervals). Discussion Based on our results, it is possible to speculate that patients with schizophrenia are at a risk of developing cardiac arrhythmia and cardiac dysfunction if they do not receive treatment. For this reason, clinicians should pay attention to cardiac transmission problems when organizing the treatment of patients. Further studies should be conducted to determine cardiac problems in patients with schizophrenia.

“… 27 In some studies, a relationship was reported between Tp-e range and the increase in the Tp-e/QTc ratio and the risk of fatal ventricular arrhythmia. 28 , 29 QT and Pd were examined in studies conducted with ECG results in psychiatric patients. Tp-e interval and Tp-e/QTc ratio were dealt with in fewer studies.…”

“…Masdrakis et al [23] published data of 9 patients treated with ECT, with no prolonged QTc in ECG or adverse cardiovascular incidents. A recent study by Coskun et al [27] showed no increase in ventricular repolarization heterogeneity (Tp-Te, Tp-Te/TQc, JTc and JTd) in patients treated with ECT.…”

BackgroundElectroconvulsive therapy (ECT) is an effective treatment method used in psychiatry; however, its cardiac safety has not been clearly demonstrated. The aim of the study was evaluation of the ECT effects on the myocardium based on troponin T concentrations and the following ECG parameters: the spatial QRS-T angle (QRS-TA), QRS duration (QRSd) and the corrected QT interval (QTc).MethodsIn the study 44 patients (12 female and 32 male) were enrolled diagnosed with schizophrenia (n = 21) and major depressive disorders (n = 23), according to the DSM-IVR criteria. All cases were undergoing ECT procedures. The mean age of the patients was 36.9±16 years (range: 18–74). Resting ECG was recorded before performing ECG and 1 hour after. The spatial QRS-TA was reconstructed from 12-lead ECG using the inverse Dower method. Troponin T concentration was assessed before the procedure and 6 hours after ECT.ResultsNo significant changes to troponin T concentrations were observed during the ECT series. The pre-ECT value of the spatial QRS-TA was 41.1±18.9°. The follow-up examinations did not reveal any significant increase of this parameter (p = 0.09) in any of the consecutive measurements. There were no significant changes in the QTc interval duration or the QRS complex duration demonstrated before the third, fifth and last procedure in the cycle (p>0.05). No significant changes to troponin T concentrations were observed during the ECT series.ConclusionsOur findings indicate a lack of negative ECT effects on the risk of adverse cardiovascular events measured by the spatial QRS-T angle and cardiac troponin T concentration.
