Contraindications of adenosine
Treatment with adenosine is contraindicated in cases of atrioventricular block second or third degree, except for patients with pacemakers, atrial flutter, atrial fibrillation, sick sinus syndrome, ventricular tachycardia , broncoconstritiva or bronchospastic lung disease and during pregnancy .
During the period of breastfeeding , the drug brings no risk, since it ends up being eliminated quickly.
Side effects of adenosine
Although it is an effective method for treating tachycardia , adenosine may cause some side effects. Among them may be mentioned the headache, nausea, pressure in the chest, shortness of breath, a cardiac arrhythmia , the redness on the face and the feeling of imminent fall.
During the medication, there is the possibility of occurrence of episodes of asystole and transient or prolonged ventricular fibrillation. In patients with tachycardia of unknown origin, their use can lead to the manifestation of severe arrhythmias. In patients with angina, unstable, adenosine can cause increased risk of events. http://www.blueworld.co.za/blogs/nick-pineaults-theoty-about-the-global-targets-for-weight-loss-nickpineault548
