Urine Levels of Metanephrin and Normetanephrin in Patients With Frequent Ventricular Premature Complex

Completed
Conditions
Premature Ventricular Contraction
Registration Number
NCT03447002
Lead Sponsor
TC Erciyes University
Brief Summary

Enhanced automaticity process is the underlying mechanism for arrhythmias due to excess catecholamines. Catecholamines may increase in patients with PVC. Metabolites of catecholamines are metanephrine and normetanephrine. Our aim is to measure 24 hours urine levels of metanephrine and normetanephrine.

Detailed Description

Premature ventricular complex is a very frequent arrhythmia. Suggested mechanisms for PVCs are reentry, triggered activity, and enhanced automaticity. Enhanced automaticity process is the underlying mechanism for arrhythmias due to excess catecholamines. Catecholamines may increase in patients with PVC. Half-lives of catecholamines are very short and rather changeable. Therefore, 24 hours urine levels of catecholamines are the more sensitive than plasma levels. Metabolites of catecholamines are metanephrine and normetanephrine. Our aim is to measure 24 hours urine levels of metanephrine and normetanephrine.
