Comparison of proportions of left ventricular enhanced diastolic function parameters of thyrotoxicosis patients and control

Parameters	Proportions of thyrotoxicosis patients	Proportions of control	Student’s t-test value	P-value
Peak early filling velocity (E) >72 cm/s	0.34	0.02	12.77	<0.01*
Peak velocity at atrial contraction (A) >59 cm/s	0.20	0.00	4.32	<0.01*
IVRT <76 m/sec	0.30	0.04	8.41	<0.01*
EDT <179 m/sec	0.30	0.00	4.32	<0.01*

^*Represents significant value.

Abbreviations: IVRT, isovolumic relaxation time; EDT, E wave deceleration time; E, early diastolic velocity; A, velocity with atrial contraction.
