Paroxysmal atrioventricular block and right coronary artery stenosis without acute myocardial infarction.
Paroxysmal atrioventricular block is an ill-defined entity, previously described in sporadic cases in association with vasovagal reaction, coronary angiography and distal conduction disease. The occurrence of atrioventricular block in acute inferior wall myocardial infarction is related to the presence of an important right coronary artery that is occluded, the recanalisation of this vessel leads often to rapid regression of the block that is no longer pejorative. ⋯ Coronary angiography revealed significant right coronary artery stenosis. Percutaneous transluminal coronary angioplasty with implantation of stent was successfully performed.

Citalopram induced torsade de pointes, a rare life threatening side effect.
Acquired Long QT syndrome is a disorder caused by medications, electrolyte imbalances, and drug interactions. This syndrome is associated with an increased risk of a characteristic life-threatening cardiac arrhythmia, known as torsade de pointes (TdP). ⋯ After discontinuation of citalopram, the QT/QTc interval normalized after 3 days and resolved further episodes of TdP. Patients on citalopram should be monitored closely for QT/QTc interval to prevent torsade de pointes.
