What Is The Difference Between Persantine And Dobutamine
Drugs for Heart Test: Chemical stress tests are used to diagnose heart artery blockage in people who cannot treadmill exercise. Persantine is injected IV and dilates normal blood vessels more than abnormal ones causing an ischemic defect on a nuclear image. Dobutamine is injected IV and increases the heart rate and contractility with muscle fed by a blocked artery not responding as well as normal muscle. ...Read moreSee 1 more doctor answer
Cardioversion and pa: Cardioversion is usually a single large shock delivered to the heart during an arrhythmia to stop it and let it restart with a normal rhythm.

Both: Are made in the adrenal glands of the body and are released in response to a need for increased energy. The fight or flight phenomenon.

Hemoperfusion denotes blood flow into kidneys through big renal ateries and hemofiltration denotes blood flow further circulating to smaller arterioles into/through glomeruli (microfilters) and onwards where the wanted and unwanted wastes exchanged so to adjust water and electrolyte balance and others. ...Read more
1 extra carbon atom: Epinephrine has 1 more carbon & 2 more hydrogen atoms then norepinephrine. This small difference makes the molecules look different, so they interact differently with receptors, and have different effects. One example: norEpinephrine narrows blood vessels, increasing blood pressure; Epinephrine can narrow some arteries while dilating others, and can raise or lower blood pressure. ...Read moreSee 1 more doctor answer

Different effects: Both are medications given IV (into a vein) to make someone sleep. Propofol may be used as a sedative or at the start of general anesthesia (ga); etomidate is used mostly in ga. Propofol lowers blood pressure more. Etomidate may be used for stable BP in trauma or heart surgery. Both can reduce or stop breathing and must be given under anesthesiologist supervision with careful monitoring. ...Read more
A lot: Aneurysm the entire three layers of the blood vessel has enlarged to a substantial degree usually 2-2.5 times normal size- called dilation of the entire blood vessel. Veins can become aneurysmal also. Vasodilation is a term for capillary dilation and low peripheral resistance and has nothing to do with aneurysm. A fluke of the english language. ...Read moreSee 1 more doctor answer
