*β-blockers are first line therapy in CPVT because of their sympatholytical effect. However, β-blockers are not fully protective in all CPVT patients. | *β-blockers are first line therapy in CPVT because of their sympatholytical effect.

*Left cardiac sympathetic denervation<cite>Wilde</cite> can be done in selected patients and largely prevents norepinephrine release in the heart and may therefore reduce adrenergically mediated arrhythmias. | *Left cardiac sympathetic denervation<cite>Wilde</cite> can be done in selected patients and largely prevents norepinephrine release in the heart and may therefore reduce adrenergically mediated arrhythmias. | ||
*The need for ICD therapy needs careful judgement since ICDs might not offer the ultimate protection in CPVT because of the fact that both appropriate and inappropriate shocks can trigger catecholamine release, resulting in arrhythmic ICD storms and death. | *The need for ICD therapy needs careful judgement since ICDs might not offer the ultimate protection in CPVT because of the fact that both appropriate and inappropriate shocks can trigger catecholamine release, resulting in arrhythmic ICD storms and death. | ||
