SUMMARY OF THE METHOD
Patients will be divided into two groups of 40 based on gestational age. Group A (those who are at 42 weeks of gestation and above) Group B (those who are less than 42 weeks of gestation)
After obtaining informed consent from the patients, venous access will be established with an 18 G peripheral vein cannula and standard monitoring (ECG, SpO2, NIBP) will be applied to the patients who will be taken to the operation room. Basal systolic arterial pressure (SAP) and heart rate (HR) will be recorded. The first ECG will be done in the operating room before the procedures are performed by surgical nurse. Both groups will receive volume replacement with 10 ml/kg 0.9% isotonic NaCl for 30 minutes before anesthesia. The second ECG recording will be performed. The patients will be placed in a sitting position and the puncture site will be disinfected with 10% povidone-iodine antiseptic solution. After sterile draping, 2.5 ml hyperbaric bupivacaine will be administered by reaching the subarachnoid space with a 25 G Quincke spinal needle from the L3-L4 or L4-L5 space administered by registered anaesthesist. Following the application, patients will be placed on their back.
In all cases, a 12-lead ECG recording will be taken while resting in the supine position after resting for at least 10 minutes, with a paper speed of 25 mm per second, a height of 10 mm/Mv and a filter range of 0.16-100 Hz. In ECG evaluation, QT and Tp-e interval measurements will be calculated with the help of magnifying glasses. ECGs will be measured before the operation (T1), after spinal anesthesia (T2), at the 5th minute after spinal anesthesia (T3), at the 10th minute after spinal anesthesia (T4) and at the 30th minute after spinal anesthesia (T5).

Summary
Brief summary
Spinal anesthesia is a frequently used method in cesarean section operations. Spinal anesthesia applications can also cause these rhythm disorders. With our study, we aimed to investigate the effects of spinal anesthesia on the frontal QRS-T angle in term and postterm pregnant women who are planned for elective Caesarean section.
