Sammanfattning
Sudden unexpected cardiac arrest is one of the most common causes of death in the western world. The most common risk factors are coronary artery disease and heart failure. Sources in the literature claim that, in sporadic cases, many drugs used for both cardiac and non-cardiac disorders can increase the risk of life-threatening ventricular arrhythmia by extending the QT interval (pro-arrhythmic drugs). A relatively recent study claims that 2% of the Swedish population is taking a potentially pro-arrhythmic drug every day. There is a clear-cut need for more knowledge and understanding of the relationship between the intake of potentially pro-arrhythmic drugs and the risk of sudden unexpected cardiac arrest.
