CARDIAC ARRHYTHMIAS

Cardiac Arrhythmia

Variation in normal rhythm OR abnormal rhythm of heart beat is called cardiac arrhythmia.

Causes:

• Abnormal rhythmicity of pace-maker (SA node)

• Shift of pace-maker from normal pace-maker SA node to elsewhere.

• Blocks at different points in impulse transmission thru conductive system.

• Abnormal pathways of impulse transmission.

• Spontaneous generation of abnormal impulses in any part of heart.

At the end of the lesson student should be able to learn about:

  • The abnormal sinus rhythms.
  • Abnormal Cardiac rythms that result from impulse conduction block.
  • The pre-mature contractions.
  • Paroxysmal Tachycardia.
  • Atrial Fibrillation.
  • Ventricular Fibrillation.
  • Circus movements.
