A heart condition caused by an extra electrical pathway between the atria and ventricles that bypasses the normal AV node. WPW can cause fast heart rhythms and, in rare cases where atrial fibrillation develops, sudden cardiac arrest. Catheter ablation is curative in the majority of cases.
Ventricular fibrillation (VF) is a life-threatening heart rhythm disturbance and the most common cause of sudden cardiac arrest. Instead of contracting in a coordinated sequence, the ventricles (the heart’s lower pumping chambers) produce rapid, chaotic electrical signals that cause the muscle fibres to quiver rather than pump. The result is an immediate and complete loss … Read more
A ventricular septal defect (VSD) is a hole in the ventricular septum, the muscular wall separating the left and right ventricles of the heart. VSDs are the most common congenital heart defect, occurring in approximately 2 to 5 per 1,000 live births. They may also develop as a rare but serious complication following a myocardial … Read more
