ECG Changes in Chronic Obstructive Pulmonary Disease (COPD)

  • Post category:ECGs
  • Right Axis Shift of P waves with prominent P waves (P Pulmonale – Right Atrial Enlargement (RAE)) in inferior leads (II , III , aVF) and flat or inverted P waves in lateral leads (I and aVL)
  • Right Axis Deviation
  • Low QRS Voltage in left precordial leads (V4-V6)
  • Poor R wave progression with delayed R/S transition in precordial leads, with sometimes persistance of S wave in V6 and absence of R waves in V1-V3 (“SV1-SV2-SV3” sign)
  • Right ventricular hypertrophy
  • Right bundle branch block
  • Multifocal atrial tachycardia
