“…Of the ventricular features, QT and QTc dispersion, QTc prolongation, and TpTe appeared promising, exhibiting significantly longer lengths with elevated BP. As with atrial features, there are numerous confounders and comorbidities that may affect ventricular features, such as age, sex, obesity, diabetes mellitus, obstructive sleep apnea, dynamic exercise, and electrolyte levels (86)(87)(88)(89). When articles containing confounders were removed, the number of significant articles decreased and the results are summarized in Figure 3.…”

Assessment of Hypertension Using Clinical Electrocardiogram Features: A First-Ever Review

Hypertension affects an estimated 1.4 billion people and is a major cause of morbidity and mortality worldwide. Early diagnosis and intervention can potentially decrease cardiovascular events later in life. However, blood pressure (BP) measurements take time and require training for health care professionals. The measurements are also inconvenient for patients to access, numerous daily variables affect BP values, and only a few BP readings can be collected per session. This leads to an unmet need for an accurate, 24-h continuous, and portable BP measurement system. Electrocardiograms (ECGs) have been considered as an alternative way to measure BP and may meet this need. This review summarizes the literature published from January 1, 2010, to January 1, 2020, on the use of only ECG wave morphology to monitor BP or identify hypertension. From 35 articles analyzed (9 of those with no listed comorbidities and confounders), the P wave, QTc intervals and TpTe intervals may be promising for this purpose. Unfortunately, with the limited number of articles and the variety of participant populations, we are unable to make conclusions about the effectiveness of ECG-only BP monitoring. We provide 13 recommendations for future ECG-only BP monitoring studies and highlight the limited findings in pregnant and pediatric populations. With the advent of convenient and portable ECG signal recording in smart devices and wearables such as watches, understanding how to apply ECG-only findings to identify hypertension early is crucial to improving health outcomes worldwide.

“…Furthermore, the heart rate, Tpeak–end (Tp-e), Tp-e dispersion, and Tp-e/QT ratio were evaluated. The TpTe was measured via the tangent method in precordial derivations [ 8 ]. The QT dispersion (QTd) is the difference between QT max and QT min on the surface ECG that reflects the time from the start of depolarization to the end of repolarization.…”

In pediatric patients with hemolytic uremic syndrome (HUS), cardiac involvement and autonomic nervous system function can be evaluated by a non-invasive method called heart rate variability (HRV). This study aims to evaluate heart rate variability and electrocardiography findings in patients with HUS by comparing a healthy group. Patients who are diagnosed with HUS at a university hospital from December 2020 to June 2022 are screened by electrocardiography (ECG), echocardiography, and 24-h Holter ECG. A healthy control group, compatible in age and gender with the patient group, was selected from healthy subjects. HRV parameters, laboratory values, and ECG findings were analyzed and compared with the healthy group and each other. There were 25 patients with HUS and 51 participants in the healthy control group. Statistically significant differences were found in some HRV parameters: standard deviation of normal to normal intervals, the mean of the 5-min RR interval standard deviations, the standard deviation of 5-min RR interval means, the triangular interpolation of normal to normal interval, and very-low-frequency power. HUS patients had impaired and declined HRV values compared to the healthy group. There was a significant decrease in the PR distance, while a significant increase in the corrected QT and QT dispersion values was detected in the electrocardiographic findings of the patient group. HRV values impaired as renal failure parameters increased. Conclusion: Patients with HUS may have autonomic nervous system dysfunction. HRV measurement is a non-invasive method that can evaluate this. It can be thought that there may be an increased risk of cardiovascular events and arrhythmias in some patients with HUS. ECG should be also considered to detect arrhythmia. What is Known:• Hemolytic uremic syndrome (HUS) primarily effects the hematologic parameters and kidney.• Secondary cardiomyopathy with hypertension and renal failure could be observed in these patients.• Rhythm problems are not expected primarily in these patients.• There is very limited data in evaluating autonomic function and arrhythmia risk for these patients. What is New:• Patients with HUS may have autonomic nervous system dysfunction.• HRV measurement is a non-invasive method that can evaluate this.• Cardiovascular events and arrhythmias due to the deterioration of the balance between the sympathetic and parasympathetic systems could manifest in patients with HUS.• An ECG and screening patients for cardiac events, and monitoring them closely should be considered.

“…Desde hace casi una década 6 se ha identificado que la prolongación de la rama descendente de la onda T del electrocardiograma (ECG) pudiera determinar riesgo de muerte súbita de origen cardiaco. Esta anormalidad electrocardiográfica se ha estudiado en enfermedades que pueden producir muerte súbita como QTc largo 7 o QTc corto, 8,9 pero también en otras entidades como insuficiencia cardiaca, 10 miocardiopatía arritmógena de ventrículo derecho, 11 apnea del sueño, 12 hipertensión arterial 13,14 e infarto del miocardio. 15,16 Ha quedado demostrada su asociación con fibrilación ventricular y muerte, por lo menos como complicaciones del infarto.…”

“…En la literatura, el concepto se ha manejado con distintos nombres T/QT, 6 QTe/RR y QTa/RR, 10 Tpeakend, 16 TpTe, 17 Tp-e, 13 TPE, 11 Tpe, 14 entre las cuales ha prevalecido la denominación Tpeak-end/QT 16 o Tpe/ QT. 13 Nosotros propusimos excluir la duración del complejo ventricular (QRS) porque los retardos en la conducción intraventricular falsearían el resultado al aumentar la magnitud del denominador, por lo tanto, restamos ese tiempo y dividimos la rama descendente de la onda T entre el segmento jT (medido desde el punto j y hasta el fin de la onda T), a lo que llamamos índice rdT/jT o índice de Acoltzin-Rabling.…”
