“…The second group included patients with typical symptoms (n= 14), among whom 8 had I pattern, and 6 had N pattern (11). All individuals with I pattern had coronary involvement and all individuals with N pattern had no evidence of coronary involvement (11). These ndings were in line with the ndings of the current study.…”

“…Similarly, Yokuşogľu et al showed that ECG mapping can be effective in determining the need for further diagnostic measures in subjects with isolated precordial inverted T-wave (11). They showed that the sensitivity, speci city, and positive predictive value of detecting healthy individuals in terms of angiography who had an isolated precordial inverted T-wave with N pattern were 100%, 90%, and 90%, respectively (11). In another study on 86 patients with inverted T-wave showed that ECG mapping can play a role in differentiating patients with heart disease from other patients (19).…”

Introduction: Isolated precordial inverted T-wave (IPITW) is a challenging finding on electrocardiogram (ECG) due to a wide range of differential diagnoses ranging from a normal finding to coronary heart disease. The aim of this study was to determine the overall prevalence of IPITW and its underlying causes along with ECG mapping. Materials and methods: The MASHAD cohort study participants (phase II) were screened for the presence of IPITW on the ECG. Demographic and clinical information of patients with IPITW extracted from the cohort study archive. ECG mapping and trans-thoracic echocardiography were performed on randomly selected 40 participants with IPITW. These participants were divided into symptomatic and asymptomatic groups. Results: The prevalence of IPITW was 1.56%. Of the selected 40 participants (9, 22.5% male and 31, 77.5% female), IPITW was mostly present in V3 and V4 leads (77.5% in each case). There was no significant difference in the number of leads with IPITW between I, M and N patterns (p = 0.051). Hypertension, ischemic heart disease (IHD) and heart failure (HF) were the least prevalent among N pattern group. The prevalence of heart failure was the highest in M pattern group (60%). Pattern I was associated with 525.2-fold increased likelihood of IHD compared to the N pattern. I pattern had the highest sensitivity (68.42%), specificity (90.48%), positive (86.67%) and negative (76.0 %) predictive values in IHD diagnosis. Conclusions: IPITW in the presence of I pattern in ECG mapping can be an indicator for IHD.
