Acute phosphide poisoning is often fatal, often because of cardiovascular events. Cardiac involvement can be complex and requires careful monitoring to diagnose.
Manifestations may include:
(1) arrhythmias
(2) conduction disorders
(3) ischemic events
(4) toxic myocarditis
(5) hypotension and shock
Arrhythmias may include:
(1) atrial flutter or fibrillation
(2) ventricular tachycardia or fibrillation
(3) supraventricular tachycardia
(4) bradycardia-tachycardia syndrome
(5) electrical alterans
Conduction disorders may include:
(1) bundle branch block
(2) sino-atrial block
Ischemic events
(1) subendocardial
(2) atrial infarction
(3) STEMI
Risk factors contributing to the cardiac dysfunction:
(1) hypo or hypermagnesemia
(2) hypokalemia
(3) metabolic acidosis
(4) hypoxemia from ARDS
