Abstract

To assess the prevalence of abnormal electrocardiograms (ECG) recorded routinely in patients undergoing elective surgery as well as the prevalence of ECG abnormalities that could not be predicted by the patient's medical history. To determine the influence of ECG results on patient care. To identify patient groups at high risk for abnormal ECG. Retrospective study of 2,146 patients scheduled for non cardio-thoracic surgery requiring anesthesia. Two physicians reviewed the preoperative ECG reports in consultation with a cardiologist. The reports were considered normal, abnormal but expected or abnormal and unexpected based on agreement or not with the patient's medical history. The 161 (7.4%) patients for whom data was missing were excluded. Preoperative ECGs were performed in 1,898 (95.6%) cases. Abnormal ECG results were reported for 351 (18.5%), most often for men, patients over 45 years of age, those classified ASA III-V, those with cardiovascular disease, kidney failure and diabetes mellitus. Two hundred seventy unexpected abnormalities were found in 234 (12.3%) patients. Of these, 117 (43.3%) were considered major. The unexpected abnormalities motivated changes of attitude toward 4 (1.7%) patients, but new treatment was es...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
