Objectives The short QT syndrome is a cardiac channelopathy characterised by accelerated repolarisation which manifests as a short QT interval on the ECG. The definition of a short QT interval is ...

Table 1 SNPs in cardiac ion channel genes associated with QTc length in healthy Caucasian populations KCNH2 rs1805123 (K897T) and rs3815459 were in moderate LD (D′=−0.60). Haplotype analysis confirmed ...

Objective: To assess health care practitioners' ability to correctly measure the QT interval, and to identify factors and medications that may increase the risk of QT-interval prolongation and ...

ROTTERDAM, the NETHERLANDS — A new analysis of participants in a population-based cohort study suggests at least two ECGs might be useful to stratify individuals at risk for sudden cardiac death (SCD) ...

Researchers have been using artificial intelligence (AI) to develop a mobile device that can identify certain patients at risk of sudden cardiac death. Researchers from Mayo Clinic and AliveCor Inc.

As more consumer-facing devices add features to measure the heart’s electrical activity, companies are looking for new ways to turn this data into valuable health information. AliveCor, a startup that ...

The ECG findings of hyperkalemia change as the potassium level increases. From earliest to latest, the ECG findings include: Peaked T waves best seen in the precordial leads, shortened QT interval and ...

This cohort study assessed ECG parameters in transgender men and women before and after use of gender-affirming hormone therapies. Testosterone use in transgender men was associated with shorter ...

Gender-affirming hormone therapies (GAHT) were associated with some cardiac repolarization alterations evident on electrocardiography (ECG), the QTrans cohort study showed. ECG features were reported ...
