There are several studies evaluating the cardiac effects of carbon monoxide (CO) poisoning during the acute period; however, the number of studies evaluating the long-term cardiac effects is limited. ⋯ In patients presenting to the ED with CO poisoning, COHb levels can be helpful for risk stratification in the long-term development of AMI.

Brugada syndrome is an inherited heart disease without structural abnormalities that is thought to arise as a result of accelerated inactivation of Na channels and predominance of transient outward K current to generate a voltage gradient in the right ventricular layers. Brugada syndrome occurs in patients with structurally normal heart and predisposes patients to malignant ventricular arrhythmias. Acute pulmonary embolism has been associated with a variety of electrocardiograms,and rarely, it may mimic electrocardiographic pattern of Brugada syndrome and this condition was defined as Brugada phenocopy.
