Pulse Rate can be taken as a marker for serum levels of T3 and T4 in thyrotoxic patients.

Abstract

Abstract:Background: The study was designed to evaluate the correlation between clinical parameters:(pulse rate and pulse pressure) and serum levels of triiodothyronine (T3) and thyroxine (T4) in thyrotoxic patients.Setting: The Specialized Centre for Endocrinology and Diabetes, Baghdad, Iraq.(2002 – 2003)Design: Randomized biochemical screening study.Outcome measures:-serum levels of T3 and T4, Resting pulse rate, and pulse pressure.Results: statistically significant positive correlation between T3 and T4 levels and pulse rate (r=0.428 p<0.01, r=0.328 p<0.05 respectively). While no significant correlation was found between pulse pressure and neither T3 nor T4.Conclusion: the study suggests using pulse rate as measured clinically as a marker for serum levels of T3 and T4 in thyrotoxic patients.Key words: T3, T4, pulse rate, thyrotoxicosis.
