Which Substances Can Cause Ventricular Fibrillation?
Several toxins and drugs can precipitate VF. These include:
Cardiotoxic drugs such as digoxin, which can cause arrhythmias at toxic levels. Stimulants like cocaine and methamphetamine, which can induce VF through excessive sympathetic stimulation. Electrolyte imbalances caused by diuretics or other medications, which disrupt the normal ionic currents in cardiac cells. Environmental toxins such as carbon monoxide and cyanide, which impair cellular respiration and cardiac function.
