ECG: low voltatge QRS complexes

ECG: low voltatge QRS complexes

• • No QRS with an absolute value equal or >0.1 mv (10 mm), OR

  • No limb lead QRS equal or >0.05 mV (5 mm)

Causes:

• • Decreased voltage production by the myocardium

    • Restrictive CM (amyloidosis, sarcoidosis)

    • Hypothyroidism

  • Increased impedance between voltage producing source and ECG leads

    • Fat (obesity)

    • COPD, PTx

    • Ascites

    • Pericardial effusion

    • Pleural effusion

    • Diffuse CAD
