Causes

Intrinsic Etiology

• Congenital
• Degenerative (Lev’s and Lenegre’s)
• Ischemia
• Infiltrative (Sarcoidosis, Amyloidosis, Hemochromatosis)
• Inflammatory (systemic lupus erythematosus (SLE), Scleroderma, rheumatoid arthritis (RA))
• Myopathic (Myotonic Dystrophy, Erbs Palsy)
• Infectious (Lyme, Endocarditis, Chagas)
• Trauma (Valve Replacement, Line insertions)

Extrinsic Etiology

• Autonomic (Carotid hypersensitivity, situational, vasovagal)
• Medications (Beta blockers, calcium-channel blocker (CCB), Digoxin, Clonidine, antiarrhythmics)
• Hypothyroidism
• Hypothermia
• Neurologic
• Electrolytes (Hyperkalemia, Hypokalemia)
