The Effect of Severe Pain on Transmyocardial Repolarization Parameters ın Renal Colic Patients

Introduction
In this study, we aimed to evaluate changes of transmyocardial repolarization parameters in renal colic patients with severe pain. Our secondary aim was to evaluate the changes in these parameters after pain relief.
Materials and Methods
The study was a prospective observational study. Patients with known urolithiasis and severe pain and without any cardiac disease were included. A control group was created from healthy volunteers of similar ages and sex. Electrocardiographies (ECG) were taken at the time of admittance and one hour after pain relief. The data were analyzed with the SPSS 16 program.
Results
100 renal colic patients and 100 healthy volunteers were included in the study. Median age and sex of the patients in the patient group and the control group were similar. The heart rates and myocardial parameters of the patients were higher than those in the control group. In the patient group, heart rate, P wave duration, QTc, Tp-e interval and Tp-e/QTc rates were decreased in the ECGs that were taken after pain relief, and these differences were statistically significant (p<0.005 all values).
Conclusion
We observed several responses in the cardiovascular system due to acute pain. Myocardial parameters were prolonged during severe acute pain. Severe pain, such as that from renal colic, may cause cardiac responses, such as arrhythmias.
