From the Research

Hiatal Hernia and EKG Changes

  • A hiatal hernia can cause cardiac complications, including arrhythmias and electrocardiographic changes 1, 2, 3.
  • Studies have shown that hiatal hernias can lead to left atrial compression, which can impair left atrial filling and cause changes in EKG readings 4, 3.
  • The compression of the heart by a hiatal hernia can cause dynamic electrocardiographic changes, including T wave inversion and ST segment elevation 3.
  • In some cases, hiatal hernias can cause complete heart block, which can be resolved with deflation of the gastric contents or surgical repair of the hernia 2.
  • Echocardiography can be used to diagnose hiatal hernias and assess their impact on cardiac function, including the compression of the left atrial cavity 4, 1.

Cardiac Complications of Hiatal Hernias

  • Hiatal hernias can cause a range of cardiac complications, including arrhythmias, such as sinus tachycardia, atrial flutter, and ventricular tachycardia 1.
  • Large hiatal hernias can become incarcerated, leading to ischemia in herniated tissues and requiring acute surgical intervention 5.
  • The risk of complications associated with hiatal hernia repair is high, particularly in acute surgery and in elderly patients with co-morbidities 5.

Diagnosis and Treatment

  • Hiatal hernias can be diagnosed using echocardiography, computed tomography, and endoscopy 4, 1, 2, 3.
  • Treatment of hiatal hernias typically involves surgical repair, which can resolve cardiac complications and improve symptoms 2, 5, 3.
  • In some cases, deflation of the gastric contents using a nasogastric tube can help to resolve cardiac complications, such as complete heart block 2.
