This broader search strategy eliminated the term “HCM”. Subsequently, a broader search (Search 2) was conducted to determine if viable articles were omitted in the first search. The initial search (Search 1) consisted of the following terms: “dagger Q wave”, “dagger-like Q waves”, “dagger shape Q waves”.
#Pathological q wave on ecg software#
The Rayyan systemic review software was used to screen articles for final review. The databases PubMed, Web of Science, Scopus and cumulative index to nursing and allied health literature (CINAHL) were searched utilizing the preferred reporting items for systematic reviews and meta-analyses (PRISMA) format. A secondary goal is to review other pediatric conditions that can present with pathologic and non-pathologic Q waves. The primary goal of this systematic review of the literature is to describe the prevalence of pathologic Q waves in the ECGs of pediatric patients with echocardiogram proven HCM. Furthermore, other pediatric health conditions have also been associated with pathologic and non-pathologic Q waves and an awareness of those conditions is important to consider when Q waves are observed. The prevalence or frequency of this finding in pediatric HCM patients, however, is not well-established. Deep Q waves in the inferior and lateral leads are one of the classic ECG findings associated with HCM. The electrocardiogram (ECG) of patients with hypertrophic cardiomyopathy (HCM) ranges from normal to exhibiting evidence of ventricular hypertrophy, including pathologic Q waves and ST-T wave changes.
