Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The most prevalent arrhythmias during pregnancy are atrial arrhythmias. However, ventricular tachyarrhythmias are exceedingly rare during pregnancy and may be life-threatening.
Caesarean section is one of the most common surgical procedures. General anaesthesia, spinal anaesthesia and epidural anaesthesia can be employed in these patients. Spinal anaesthesia is a frequently employed method in caesarean section operations due to its rapid onset of effect, technical simplicity of application and higher probability of success.
In pregnant women, anaemia is defined as a haemoglobin concentration below 11 mg/dL in the first trimester, 11 mg/dL in the second trimester and 10.5 mg/dL in the third trimester.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Pregnancy has a profound effect on the cardiovascular system. It results in an increase in blood volume, heart rate, venous pressure in the lower extremities, and cardiac output. Furthermore, it can result in a reduction in peripheral resistance and pulmonary vascular resistance, as well as a decline in blood pressure. Furthermore, it affects the cardiac conduction system, rendering patients more susceptible to arrhythmias. The most prevalent arrhythmias during pregnancy are atrial arrhythmias. Ventricular tachyarrhythmias are relatively uncommon during pregnancy and can be life-threatening.
One of the most common surgical procedures is caesarean section. General anaesthesia, spinal anaesthesia and epidural anaesthesia can be employed in these patients. Spinal anaesthesia is a frequently employed method in caesarean section operations due to its rapid onset of effect, technical ease of application and higher chance of success. In addition to the beneficial effects, direct cardiac and indirect cardiac side effects may be observed, such as vasodilatation due to sympathetic denervation, decreased right heart pressure and reflex bradycardia, which depend on the level of block.
In pregnant women, haemoglobin values below 11 mg/dL in the first trimester, 11 mg/dL in the second trimester and 10.5 mg/dL in the third trimester are considered to indicate anaemia.
The objective of this study was to investigate the effects of spinal anaesthesia in elective caesarean section cases on frontal QRS angle in anaemic and non-anaemic patients.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Patients who had undergone Elective Cesarean Surgery with anemia
In pregnant women, haemoglobin values below 11 mg/dL in the first trimester, 11 mg/dL in the second trimester and 10.5 mg/dL in the third trimester indicate anaemia.
The group comprised patients with haemoglobin levels below 10.5 mg/dL.
No interventions assigned to this group
Patients who had undergone Elective Cesarean Surgery without anemia
In pregnant women, haemoglobin values below 11 mg/dL in the first trimester, 11 mg/dL in the second trimester and 10.5 mg/dL in the third trimester indicate anaemia.
The group comprised patients with haemoglobin levels above 10.5 mg/dL.
