Background

General Causes

  • Fluid, fat or air attenuating signal
  • Myocardial infiltration
  • Loss of viable myocardium

Clinical Features

  • Frequently asymptomatic, depends on underlying cause

Differential Diagnosis

Specific causes of low voltage ECG

Low ECG voltage

Cardiac

Pericardial

Extracardiac

Diagnosis

Sample ECG
  • ECG[1]
    • QRS < 5 mm in limb leads
    • QRS < 10 mm in chest leads

Management

  • Treat underlying condition

Disposition

  • Depends on underlying condition
