Torsades de Pointes

Torsades de Pointes is a specific type of abnormal heart rhythm characterized by rapid, irregular beating that looks like twisting points on an ECG (electrocardiogram). It often occurs due to a disturbance in the heart’s electrical system, commonly caused by electrolyte imbalances, certain medications, or genetic conditions affecting ion channels. This arrhythmia can lead to dizziness, fainting, or even sudden cardiac arrest if not treated promptly. Management typically involves correcting underlying causes, stopping triggering medications, and sometimes using defibrillation or medications to restore normal rhythm.
