Ventricular tachycardia arises from an abnormal electrical focus or circuit in the myocardium of the ventricle and is usually manifested as a tachyarrhythmia with a wide QRS complex on ...

The correct diagnosis is sinus rhythm with premature ventricular contractions and ventricular parasystole (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is irregular. There are ...

Adding functional imaging to structural imaging of patients with ventricular tachycardia (VT) has the potential to improve current VT ablation strategies, according to new research. Adding functional ...

During embryonic development, the right ventricle is formed from the secondary heart field into a crescent-shaped, thin-walled structure. 6 It is the most anterior heart chamber, sitting just beneath ...

Although premature ventricular beats (PVBs) in young people and athletes are usually benign, they may rarely mark underlying heart disease and risk of sudden cardiac death during sport. This review ...

In a recent study published in Nature Cardiovascular Research, researchers modeled the right ventricle (RV) to create a robot replicating right ventricular hemodynamics and biomechanics. Study: ...

A new study reveals that the predictive power of key inflammatory markers, such as C-reactive protein, shifts fundamentally ...

A team led by scientists at Queen Mary University of London reports that certain risk factors for heart disease are linked to common changes in the structure and appearance of the heart. Risk factors ...

This important work identifies phlda2 as a specific marker for primordial cardiomyocytes in the adult zebrafish heart and demonstrates their essential role in myocardial morphogenesis and coronary ...

As the central part of the circulatory system, the heart is responsible for pumping blood, supplying oxygen and nutrients, and removing metabolic waste such as carbon dioxide from all the tissues in ...
