BACKGROUND Reduced lung function has been associated with increased rates of myocardial infarction. Whether the occurrence and prognostic significance of ventricular arrhythmia is related to lung function is largely unknown. METHODS AND RESULTS We performed a population-based study of 68-year-old men without a history of stroke or myocardial infarction; 402 men participated. Mortality and cor...
BACKGROUND The role of programmed ventricular stimulation in identifying patients with Brugada syndrome at the highest risk for sudden death is uncertain. METHODS AND RESULTS We performed a systematic review and pooled analysis of prospective, observational studies of patients with Brugada syndrome without a history of sudden cardiac arrest who underwent programmed ventricular stimulation. We...
BACKGROUND Homozygous mutant mice expressing a truncated form of myosin-binding protein C (MyBP-C(t/t)) develop severe dilated cardiomyopathy, whereas the heterozygous mutation (MyBP-C(t/+)) causes mild hypertrophic cardiomyopathy. Adult male MyBP-C(t/t) and MyBP-C(t/+) mice were evaluated for arrhythmia vulnerability with an in vivo electrophysiology study. METHODS AND RESULTS Surface ECGs w...
BACKGROUND Mild to moderate therapeutic hypothermia (TH) has been shown to improve survival and neurological outcome in patients resuscitated from out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF) as the presenting rhythm. This approach entails the management of physiological variables which fall outside the realm of conventional critical cardiac care. Management of serum...
Cardiovascular diseases are the most dangerous diseases and one of the biggest causes of fatality all over the world. One of the most common cardiac arrhythmias which has been considered by physicians is premature ventricular contraction (PVC) arrhythmia. Detecting this type of arrhythmia due to its abundance of all ages, is particularly important. ECG signal recording is a non-invasive, popula...
BACKGROUND Patients with inherited arrhythmia syndromes are at an increased risk of sudden cardiac death (SCD). Specialized inherited arrhythmia clinics were founded to optimize management and prevention of SCD in this population. However, the clinical effectiveness of these clinics has never been evaluated. METHODS AND RESULTS Clinical outcome data of patients referred to a specialized inher...
Evaluation and treatment of patients with ventricular arrhythmias are full of pitfalls for the unwary. In this series of articles we discuss how to recognize and avoid these pitfalls and present our approach to management. The prevalence and clinical significance of ventricular arrhythmias and indications for treatment are addressed in this initial installment.
The incidence of myocardial contusion after blunt chest trauma is highly variable. The most frequent cause is traffic accident, and it can also result from blows to the body. These injuries can affect the free heart wall, the interventricular septum, valves, subvalvular apparatus, coronary arteries, and the atrioventricular or intraventricular conduction system, and can cause ventricular arrhyt...
A hallmark of cardiovascular disease is cardiac autonomic dysregulation. The phenotype of impaired parasympathetic responsiveness and sympathetic hyperactivity in experimental animal models is also well documented in large scale human studies in the setting of heart failure and myocardial infarction, and is predictive of morbidity and mortality. Despite advances in emergency revascularisation s...
