Available in PDF, EPUB and Kindle. Book excerpt: To determine mechanisms of myocardial toxicity of radiopaque media and to correlate specifically induced changes in the composition of coronary artery blood with the changes in the surface electrocardiogram, simultaneous recordings were made from Frank leads X, Y, and Z during intracoronary injections of radiopaque media and special test solutions in 19 patients. With injections of sodium-containing radiopaque media into the right coronary system the mean T vector increased in magnitude and deviated to the left and superiorly. With left coronary injections the T vector increased in magnitude and shifted to the right, downward, and anteriorly. Changes in the QRS complex were less constant but when present, consisted of slight prolongation of the QRS duration and shift of the QRS vector toward the area of myocardium perfused by the coronary system injected. Similar T vector changes could be produced by intracoronary injections of saline solutions, but minimal or no changes were observed with injections of hypertonic mannitol, Ringer's solution, hypoxic blood, plasma, and 5 per cent dextrose in water. It is concluded that the T wave changes are caused by regional prolongation of the repolarization process, presumably due to extracellular sodium excess or sodium-calcium antagonism. Delay of the repolarization process and the resulting potential difference may be responsible for reentrant excitation and the ventricular arrhythmias observed during coronary angiography. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Contrast media are drugs by default. Had there been no default, there would be no need for a related pharmacology, and thus no need for this book. Radiographic contrast media (CM) are substances whose primary purpose is to enhance diagnostic information of medical imaging systems. The position of CM in pharmacology is unique. First, there is the unusual requirement of biological inertness. An ideal CM should be completely biologically inert, i.e., stable, not pharmacologically active, and efficiently and innocuously excretable. Because they fail to meet these requirements, CM must be considered drugs. The second unusual aspect of CM is that they are used in large quantities, their annual production being measured in tens of tons. It is not in spite of, but because of, the increased use of new radiographic systems, computed tomography, digital radiography, etc., that consumption is on the rise. And, it is not likely that the other emerging imaging modalities - NMR, ultrasonography, etc. - will displace radiographic CM soon; it is quite probable that these remarkable compounds will continue to play an active role in diagnostic imaging in the foreseeable future.
