Q

Types of Arrhythmias

A
  • Fibrillations: extremely rapid, uncoordinated shuddering of HT muscle
    • Atrial Fibrillation (A-fib; AF): irregular contraction of atrial muscle tissue
    • Ventricular Fibrillation (V-fib; VF): irregular contractions of ventricular muscle tissue
      • Most common arrhythmia in cardiac arrest
      • Electrical dysfunction following ventricular tachycardia
      • Commonly associated w/ MI, CHR, shock, or other HT dx
      • S/S: Chest pain, SOB, sudden death
      • TX: Direct Current (DC) Cardioversion
  • Premature ventricular contraction (PVC): an extra contraction of ventricular muscle prior to its normal contraction. Sensation of skipped beat or “flip-flopping” in chest.
  • Heart block: disease or inherited condition w/ obstruction in electrical conduction system of HT, creating longer gap between HT sounds. Includes Sinoatrial nodal black (SA block), Atrioventricular block AV block), intra-Hisian blocks, infra-Hisian blocks, Bundle branch blocks, & Fasicular or Hemiblocks
  • Tachycardia: Rapid HT rate. Sensation HT racing or beating very fast, even w/o exertion
    • Ventricular Flutter:
      • A tachycardia affecting ventricles- possible transition stage between tachycardia and Vfib
      • HR > 250-350 BPM
      • Associated w/ hypoxia or ischemic insults
      • Hypotension, sudden death
      • TEST: ECG: sinusoidal waveform without clear definition of the QRS and T waves.
      • TX: defibrillation
