What is adenosine used for?
ADENOSINE (a DEN uh seen) is used to bring your heart back into a normal rhythm. This medicine is not useful for all types of irregular heart beats. It may be used to test the heart for coronary artery disease.
Does adenosine stop heart?
While adenosine can slow conduction through the AV node, it does not affect accessory pathways. In such cases, this can cause severe tachycardia that can deteriorate to a non-perfusing rhythm, leading to cardiac arrest.
Does caffeine block adenosine?
Caffeine is considered an adenosine blocker. It comes into play by similarly attaching itself to the same receptors that adenosine would normally latch onto. In turn, it prevents the drowsiness that occurs as the levels of adenosine in the body increase.
Is PSVT serious?
PSVT is not life-threatening. However, if you have an underlying heart condition, PSVT could increase your risk of congestive heart failure, angina, or other abnormal rhythms.
What does the name adenosine mean?
Adenosine is an important chemical known as a nucleoside that exists naturally in all cells of the body. It is used to transfer energy within the cells by forming molecules like adenosine triphosphate (ATP) and adenosine diphosphate (ADP), and it is also one of the chemical messengers, or neurotransmitters, within the brain.
How does adenosine affect blood pressure?
adenosine causes a dose-related increase in heart rate and in systolic blood pressure, while producing only a slight decrease in diastolic blood pressure.4 It was hypothesized that these effects were the result of activation by adenosine of a reflex autonomic mech-anism that is probably blunted during anesthesia. The
What does adenosine treat?
Adenosine is given intravenously by healthcare providers for treating surgical pain and nerve pain, pulmonary hypertension, and certain types of irregular heartbeat. It is also given for controlling blood pressure during anesthesia and surgery and for heart tests called cardiac stress tests.
How is adenosine administered?
Adenosine should be administered by rapid intravenous (IV) bolus injection into a vein or into an IV line. If given into an IV line it should be injected through as proximally as possible, and followed by a rapid saline flush.
