Barium Toxicity and Hypertension

• Direct Cardiovascular Impact
• Barium ions act as potassium channel blockers in cell membranes.
• This blockage leads to a significant intracellular shift of potassium, causing acute hypokalemia.

• Mechanism of Vessel Contraction
• Severe hypokalemia and direct pharmacological action of barium cause profound smooth muscle depolarization.
• This persistent depolarization triggers sustained and generalized vasoconstriction of blood vessels.

• Hypertensive Crisis
• The extreme increase in peripheral vascular resistance frequently results in marked hypertension.
• This can be accompanied by cardiac arrhythmias, muscle weakness, and paralysis due to the disrupted electrolyte balance.
