Qaddoura A, et al. - Researchers reviewed the role of fragmented QRS (fQRS's) in pulmonary embolism (PE) prognostication, using data from studies wherein fQRS was used to prognosticate patients for the main outcomes of death and clinical deterioration or escalation of therapy. A random-effects model was used to pool relevant data in meta-analysis with odds ratios (OR) and 95% confidence intervals (CI). Overall, five studies with 1,165 patients were included. The potential utility of fQRS in PE prognostication was demonstrated. Considering fQRS as an entry, along with other clinical and ECG findings, in a PE risk score, was recommended.
