Arsenic poisoning can have acute and long-term effects on the electrocardiogram.
Acute changes on the ECG:
(1) ventricular fibrillation
(2) torsades de pointes
(3) bradycardia with or without cardiac arrest
(4) prolongation of the QTc and other conduction delays
(5) ischemic-type changes secondary to myocyte necrosis (ST-T wave abnormalities)
Changes which may persist for some time after the acute intoxication:
(1) prolongation of the QTc and other conduction delays
(2) T wave inversion
