Correlation between Heart Rate Variability and Intelligence Quotientin Medical Students of Pakistan: An Exploratory Study

Authors

Abstract

Objective: To determine a correlation between autonomic systemic variability through measurement of time Domain HRV and intelligence quotient (high and average IQ) of medical college students.

Methods

It was a cross sectional study conducted at The Central Park Medical College Lahore. A total of 34 MBBS students participated. Modified Wechsler Adult Intelligence Scale (WAIS) was used to calculate the IQ of students. Assessment of autonomic function was done by determination of HRV through variables of time-domain using Lab Chart version 8.0 with HRV module installed. It utilized Data Acquisition System with application of ECG two limb leads. Mann-Whitney U test used to compare median values. Spearman's correlation was used to find any correlation.

Results

 : In our study population RMSDD, SDRR and pRR50% were compared with reference values and it was observed that our study population HRV Indices were much higher than the reference values, but the difference did not reach significance. No correlation was found between HRV of average and high IQ medical students.

Conclusion

 Time domain of Heart rate variability was much higher in the medical students as compared to the reference values, but it did not reach statistical significance when compared between average and high IQ students.
