General anaesthesia (GA) is a medically induced coma and loss of protective reflexes resulting from the administration of one or more general anaesthetic agents. A variety of medications may be administered, with the overall aim of ensuring sleep, amnesia, analgesia, relaxation of skeletal muscles, and mostly loss of control of reflexes of the autonomic nervous system. The optimal combination of these agents for any given patient and procedure is typically selected by an anaesthesiologist or another provider such as an anaesthesiologist assistant or nurse anaesthetist. The objective is to determine the side effects of general anaesthesia on the cardiovascular system, through changes in the electrocardiography (ECG). This study was conducted in Al-Sader Teaching Hospital in Missan province in Iraq. Where the collection of data was last for nine months and the work was finished at Al-Nahrain University /High institute for infertility diagnosis and ART’s. The study was included 50 patients, all of them were healthy it can be divided into 30 men and 20 women, 25 were aged less than 50 years, rest of patients were aged more than 50 years. ECG was performed for each one before the operation and ECG was normal for all patients. After a surgical operation and under general anaesthetic, taking into consideration not to give preanaesthetic medications. Within an hour after operation, the ECG was done again. The results were as follows: 39 patients with normal ECG, 23 patients were younger than 50 years, while the rest 16 were greater than 50 years, the number of men 22 and women 17. As for the remaining 11 patients, ECG showed sinus tachycardia, they were 8 men and 3 women, all of whom were aged greater than 50 years, except for two patients. There is accumulating evidence that anaesthetic management may indeed exert a number of influences on longer term postoperative out-comes. Further prospective, randomized, large scale, human trials with long- term follow-up are required to clarify the association between anaesthesia technique and postoperative outcome.
