Summary
Electrocardiography (ECG) is crucial for detecting perioperative arrhythmias, which can stem from various factors. Promptly identifying and managing these cardiac events reduces patient risk during anesthesia and surgery.
Area of Science:
- Anesthesiology
- Cardiology
- Medical Monitoring
Background:
- Electrocardiography (ECG) was the first electronic monitoring tool in anesthesia.
- Detecting cardiac arrhythmias remains a primary application of ECG in perioperative care.
- Numerous factors can predispose patients to arrhythmias during surgery.
Purpose of the Study:
- To review the causes of perioperative cardiac arrhythmias.
- To discuss the pharmacological treatment of major atrial and ventricular arrhythmias.
- To emphasize the importance of prompt evaluation and management.
Main Methods:
- Review of predisposing factors for perioperative arrhythmias.
- Analysis of key electrocardiographic findings for arrhythmia evaluation.
- Discussion of anesthetic and surgical influences on cardiac rhythm.
Main Results:
- Common causes include anesthetic agents, surgical site, blood gas/electrolyte abnormalities, tracheal intubation, reflexes, CNS stimulation, pre-existing heart disease, and intracardiac devices.
- Evaluation requires assessing heart rate, regularity, P waves per QRS, and QRS configuration.
- Determining the danger and need for treatment is critical.
Conclusions:
- Prompt evaluation and management of perioperative arrhythmias are vital for reducing morbidity and mortality.
- Understanding predisposing factors aids in preventing and treating arrhythmias.
- This review covers causes and treatments for major perioperative atrial and ventricular arrhythmias.
