Citalopram and escitalopram are examples of drugs that are used for depressive illness. They can commonly cause side effects including prolongation of QT interval especially when other risk factors are present such as age extremity, stress or shock. The exact mechanism of the effect of citalopram on QT interval, however, is not known

QuestionComment
Go on BNF and search "appendix one", then control F "QT Prolongation" and you can see all the drugs that cause it. 

Appendix one can also be used for other common electrolyte imbalances

#### Monitoring

The BNF advises to monitor lung function (in patients with a history of obstructive airway disease).

#### Overdoses

Overdosages with beta-blockers may cause cardiac effects such as bradycardia, hypotension, syncope, conduction abnormalities, and heart failure. Bradycardia is the most common arrhythmia, but some beta-blockers may induce ventricular tachyarrhythmias secondary to prolongation of QT interval (e.g. sotalol) or QRS duration (e.g. propranolol).
Non-cardiovascular effects include central nervous system effects (including drowsiness, confusion, convulsions, hallucinations, and in severe cases coma), respiratory depression, and bronchospasm.

Management
 - Airway protection 
 - Activated charcoal within 1 hour
 - IV Fluids
 
IV glucagon is the first-line management.
 
For symptomatic bradycardia, IV atropine may be used.

Case Presentation: A 75-year-old man is recovering on the Orthopaedic Ward following an elective left knee replacement two days ago. Post-operatively, he was prescribed paracetamol, an NSAID and a weak opioid for pain relief. On the second day after his operation, he developed tachycardia. An ECG was performed showing sinus tachycardia with prolongation of QT interval. PMH Severe depression, Parkinson’s disease, IBD. DH Citalopram 40mg OD, Paracetamol 1g QDS PO, Ibuprofen 400mg TDS, Co-beneldopa 50mg BD, Rotigotine 8mg TD OD
