Abstract

Kaala Patthar, containing paraphenylene diamine (PPD) chemically, is used as a hair dye in South Punjab. Recent trends have shown its increasing use as a poison. The common manifestations of Kala Patthar poisoning include upper airway edema, rhabdomyolysis, and acute renal shutdown. However, cardiac toxicity is a rare complication and the conduction abnormalities are seldom reported. We are going to report a case of permanent complete heart block after Kaala Patthar poisoning where the patient needed permanent pacemaker to save his life.
