Previous studies have reported comorbidities and risk factors for coronary artery spasms.

Immediately after the initiation of laryngoscopy, complete AV block and ST elevation on lead II of the electrocardiogram were observed. These findings indicated that the complete AV block was caused by a right coronary artery spasm.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Coronary artery spasm resulting in lethal arrhythmia rarely occurs in healthy pediatric patients.
