Adenosine is widely used in medical settings, particularly in cardiology, as a diagnostic and therapeutic agent. It is commonly administered intravenously to treat supraventricular tachycardia (SVT), a condition characterized by an abnormally fast heart rate. By temporarily slowing electrical conduction in the heart, adenosine helps restore normal rhythm. Additionally, it is utilized in stress testing to assess coronary artery disease, as it can mimic the effects of exercise on the heart by increasing blood flow. In neurology, adenosine plays a role in managing certain types of seizures and has been studied for its potential neuroprotective properties. Beyond medicine, it is also used in biochemical research to study cellular processes, including energy transfer and signaling pathways, due to its critical role in ATP (adenosine triphosphate) metabolism.
