“…FQRS-Ta predicts CRT response independently. 24 Topaloglu et al 25 initially studied an aberrant QRS-Ta and nonfunctional adrenal adenomas (NFAA). A considerable majority of patients had an aberrant QRS-Ta, which was linked to hypertension but not left ventricular hypertrophy.…”

Rozdíl os komplexu QRS a vlny T (frontal QRS-T angle, fQRSTa) je elektrokardiografi cký parametr odrážející prostorový vztah mezi vektory depolarizace a repolarizace v srdci; určují jej úhly mezi vektory QRS a vlnou T ve frontální rovině. Širší fQRSTa je obecně spojován se zvýšenou komorovou ektopickou aktivitou, poruchou funkce levé komory a zvýšeným rizikem kardiovaskulárních onemocnění (KVO); podle několika studií je širší QRSTa spojen se zvýšeným rizikem rozvoje KVO včetně infarktu myokardu, srdečního selhání a náhlé srdeční smrti. Celkově lze z dostupných důkazů usuzovat, že fQRSTa je užitečný marker kardiovaskulárního rizika a může mít značný význam pro prevenci a léčbu KVO. Poznání vztahu mezi QRSTa a KVO si nicméně vyžádá další výzkum, který zároveň pomůže stanovit optimální využití tohoto ukazatele v klinické praxi.

“…Recent studies have demonstrated that FQRST enlargement is associated with the aging process [6], the risk of cardiac arrhythmias, such as atrial fibrillation [7], hypertension [8], the severity of coronary artery disease and myocardial infarction [9,10], heart failure [11], idiopathic dilated cardiomyopathy [12], etc. It is also recommended for stratifying cardiac risk [13] and for monitoring patients after cardiac resynchronization therapy [14], myocardial revascularization, or cardiac valve surgery [15].…”

Background: The heart’s electrical activity has been the subject of numerous research concerning various physiological parameters. The frontal QRS-T angle (FQRST) is an advanced ECG variable with clinical epidemiological utility. This study aimed to determine the relationship between FQRST and physical activity exposure among young adults. Methods: We recorded the ECG with 12 leads of 124 participants (mean age 20.28 ± 2.23 years, age range 18–27 years). Next, we measured their physical activity level (PAL) with the International Physical Activity Questionnaire—Short Form (IPAQ), which categorizes activity into three classes: low, moderate, or high. Results: An inferential analysis, based on the Kruskal-Wallis H test and Mann–Whitney U test, revealed a statistically significant difference in FQRST between the three groups of subjects, classified by their PAL (p < 0.001). We also identified a significant regression model between the body mass index (BMI) and the FQRST (p < 0.001). Conclusions: The physical activity regime of young adults significantly influences the concordance between ventricular depolarization and repolarization, reflected in the FQRST’s width. Also, we found a regression model between FQRST and BMI with statistical significance.

Acute pancreatitis (AP) is a disease that poses significant health risks with potential severe outcomes. Identifying markers for severity can aid in early intervention and improve prognoses. This study, conducted in the emergency department, investigates the QRS–T angle as a potential indicator of severity in patients with acute pancreatitis. This retrospective study included 367 patients diagnosed with AP, classified as either mild acute pancreatitis or severe acute pancreatitis based on Ranson criteria. The QRS–T angle was measured using standard 12-lead electrocardiogram, and the data were analyzed to compare the QRS–T angles between the mild acute pancreatitis and severe acute pancreatitis groups. This research adhered to the guidelines outlined in the Strengthening the Reporting of Observational Studies in Epidemiology statement. The study included 367 patients, 94% (n = 345) had mild pancreatitis while 6% (n = 22) had severe pancreatitis. Severe cases had a significantly higher median age (P < .001) and higher rates of hypertension and diabetes mellitus (P = .027, P = .011). Severe cases also had higher Ranson scores (3 [IQR 3–3.25] vs 1 [IQR 1–2], P < .001) and longer hospital stays (6 [IQR 2.75–11.5] days vs 3 [2–5] days, P = .029). Additionally, severe pancreatitis group showed higher QRS–T angle (P < .001), higher rates of abnormal QRS angles (31.8% vs 10.1%, P = .002), and QRS–T angles (31.8% vs 8.1%, P < .001). The QRS–T angle may serve as a valuable clinical tool for differentiating between mild and severe forms of acute pancreatitis. This could potentially help clinicians in stratifying patients according to their risk and tailoring their management accordingly.
