Abstract
OBJECTIVES: The purpose of this study is to explore the value of P-wave terminal force in lead V1 (PTFV1) in the clinical diagnosis of tuberculous constrictive pericarditis (TCP). METHODS: A total of 53 patients with TCP and 64 patients with tuberculous exudative pericarditis were enrolled in this retrospective study. The demographic and clinical characteristics were collected, including gender, age, the course of disease and New York Heart Association (NYHA) classification. Besides, echocardiography data also were obtained, including left atrial diameter, left ventricular end-diastolic diameter and left ventricular ejection fraction. In addition, the parameters of electrocardiogram (ECG) were obtained, such as heart rate, the time from the corrected ORS wave origin to T-wave terminal, atrial fibrillation, right bundle branch block, atrial premature beat, and PTFV1 value. RESULTS: No significant differences were found in age, gender, the course of disease, echocardiography results, ECG parameters (in addition to PTFV1) between patients with TCP and patients with tuberculous exudative pericarditis. The percentage of patients located in NYHA class IV in the patients with TCP was significantly higher than those of patients with tuberculous exudative pericarditis (p = 0.041). Moreover, the incidence rate of abnormal PTFV1 (≤ -0.04 mm·s) was obviously higher in patients with TCP than those of patients with tuberculous exudative pericarditis (64.2% vs 9.4%, p < 0.001). CONCLUSIONS: Abnormal PTFV1 (≤ -0.04 mm·s) is associated with TCP, and PTFV1 may be a potential novel diagnostic indicator for TCP diagnosis.
