Perioperative arrhythmia

Perioperative Arrhythmia

Perioperative arrhythmias are emergencies that occur during or immediately after a surgery. Patients with perioperative arrhythmias may experience rapid heart rates, slow heart rates, or variations from normal heart rhythm. These arrhythmias can cause significant distress to patients and compromise their recovery from the surgery.

Patients at risk for perioperative arrhythmias include those with pre-existing cardiovascular conditions, those using certain medications, and those undergoing specific types of surgeries. It is important for patients to be aware of the risks and to inform their medical team of any potential concerns before undergoing surgery.

Common Causes of Perioperative Arrhythmia

Common causes of perioperative arrhythmia include:

  • Pre-existing cardiovascular conditions
  • Certain medications
  • Surgeries on the chest area
  • Airway manipulation during general anesthesia
  • Hypoxia
  • Hypotension
  • Hypercarbia
  • Electrolyte imbalance

Symptoms of Perioperative Arrhythmia

Patients with perioperative arrhythmias often experience abnormal heartbeats, lightheadedness, fatigue, and shortness of breath. These symptoms can signal a potentially serious arrhythmia, such as atrial fibrillation or ventricular tachycardia.

Diagnosis of Perioperative Arrhythmia

Diagnosis of a perioperative arrhythmia often involves an electrocardiogram (ECG). During an ECG, a doctor will take a recording of the patient's heart rhythm from several electrodes placed on the chest. The ECG can detect any abnormalities in the heart rhythm that may indicate a serious arrhythmia. Depending on the type of arrhythmia, a doctor may also order other tests such as echocardiogram or an exercise stress test.

Treatment of Perioperative Arrhythmia

Treatment of a perioperative arrhythmia depends on the underlying cause. If the patient is experiencing a rapid, irregular heartbeat, they may need anti-arrhythmic medications or a pacemaker. In some cases, a doctor may recommend a catheter ablation to destroy abnormal electrical pathways in the heart.

Patients should follow their doctor's recommendations and take medications as prescribed. Maintaining a heart-healthy lifestyle with regular exercise, a balanced diet, and stress management can also help prevent perioperative arrhythmias.
