Reversed Apico-Basal Myocardial Relaxation Sequence During Exercise in Long QT Syndrome Mutations Carriers With History of Previous Cardiac Events
ConclusionLQTS patients show reversed longitudinal relaxation sequence, which worsens with exercise, particularly in those with previous cardiac events.

Epidemiology and Clinical Characteristics of Atrial Fibrillation in Patients with Inherited Heart Diseases
ConclusionUp to one third of inherited heart disease patients will develop AF. While common general population risk factors are key in patients with HCM, genotype is independently associated with AF. Amongst inherited arrhythmia syndromes, AF is less common, though often occurs below the age of 50 years.This article is protected by copyright. All rights reserved.

Prolonged Corrected QT Interval in the Donor Heart: Is There a Risk?
ConclusionQTc > 500 msec in the donor heart appears to be an independent risk factor for the development of early CAV after heart transplantation possibly due to a higher immunological risk.This article is protected by copyright. All rights reserved.

Epidemiology of arrhythmias and sudden cardiac death in Asia.
Abstract Cardiac arrhythmias are cardiac rhythm disorders that comprise an important epidemiological and public health problem. Cardiac arrhythmias are significantly associated with increased risks of cardiovascular complications and sudden death, consequently leading to decreased quality of life, disability, high mortality, and healthcare expense. Atrial fibrillation (AF) is the most common sustained arrhythmia, and has been further increasing with the aging of society. Although the prevalence is relatively lower in Asians than in Westerners, the prognostic impacts on stroke and mortality in Asians are comparable...

Cardiovascular Genomics
Conclusions: Currently, there are no clinically recommended genetic tests for many common forms of CVD even though direct‐to‐consumer genetic tests are being marketed to healthcare providers and the general public. On the other hand, genetic testing for patients with certain single gene conditions, including channelopathies (e.g., LQTS) and cardiomyopathies (e.g., HCM), is recommended clinically. Clinical Relevance: Nurses play a pivotal role in cardiogenetics and are actively engaged in direct clinical care of patients and families with a wide variety of heritable conditions. It is important for nurses to understand c...

Clues To Gender Disparity In Human Hearts Revealed By Genes
Healthy men and women show little difference in their hearts, except for small electrocardiographic disparities. But new genetic differences found by Washington University in St. Louis researchers in hearts with disease could ultimately lead to personalized treatment of various heart ailments. Generally, men are more susceptible to developing atrial fibrillation, an irregular, rapid heartbeat that may lead to stroke, while women are more likely to develop long-QT syndrome, a rhythm disorder that can cause rapid heartbeats and sudden cardiac death...
