the AV node. For the two rates to be different, the rate of conduction would have to be different depending on the direction of the impulse. This is possible. Procainamide and amiodarone were also suggested by some as management. However, they have very limited success in refractory SVT, especially SVT that involves AV nodal conduction.

86. Is it VT or SVT with Aberrancy?

). Choice of anti-dysrhythmic for recurrent refractory or recurrent VT is beyond the scope of this blog post, but you can start by looking at the for stable VT: procainamide was better than amiodarone. In short, the literature on pharmacologic therapy for VT is terrible, whether using it for stable VT, refractory VT, or recurrent VT.

87. Purification of human butyrylcholinesterase from frozen Cohn fraction IV-4 by ion exchange and Hupresin affinity chromatography. Full Text available with Trip Pro

Purification of human butyrylcholinesterase from frozen Cohn fraction IV-4 by ion exchange and Hupresin affinity chromatography. Human butyrylcholinesterase (HuBChE) is being developed as a therapeutic for protection from the toxicity of nerve agents. An enriched source of HuBChE is Cohn fraction IV-4 from pooled human plasma. For the past 40 years, purification of HuBChE has included affinity chromatography on procainamide-Sepharose. The present report supports a new affinity sorbent, Hupresin (...) by 90% when the paste was stored at -20°C for 1 year, and reduced 100% when stored at 4°C for 24h. No reduction in HuBChE recovery occurred when paste was stored at -80°C for 3 months or 3 years. Hupresin and procainamide-Sepharose were equally effective at purifying HuBChE from Cohn fraction. HuBChE in Cohn fraction required 1000-fold purification to attain 99% purity, but 15,000-fold purification when the starting material was plasma. HuBChE (P06276) purified from Cohn fraction was a 340 kDa

91. Arrhythmogenic drugs can amplify spatial heterogeneities in the electrical restitution in perfused guinea-pig heart: An evidence from assessments of monophasic action potential durations and JT intervals. Full Text available with Trip Pro

with clinically proved proarrhythmic potential (dofetilide, quinidine, procainamide, and flecainide) and, if so, whether these effects can translate to the appropriate changes of the ECG metrics of ventricular repolarization, such as JT intervals. In isolated, perfused guinea-pig heart preparations, monophasic action potentials and volume-conducted ECG were recorded at progressively increased pacing rates. The APD90 measured at distinct ventricular sites, as well as the JTpeak and JTend values were plotted (...) as a function of preceding diastolic interval, and the maximum slopes of the restitution curves were determined at baseline and upon drug administration. Dofetilide, quinidine, and procainamide reverse rate-dependently prolonged APD90 and steepened the restitution curve, with effects being greater at the endocardium than epicardium, and in the right ventricular (RV) vs. the left ventricular (LV) chamber. The restitution slope was increased to a greater extent for the JTend vs. the JTpeak interval

93. Management of drug-induced immune and secondary autoimmune, haemolytic anaemia

IVIg can also cause acute haemolysis related to passive transfer of antibodies e.g. to ABO or Rh antigens. Some drugs (e.g. fludarabine, cladribine, levodopa, mefenamic acid and procainamide) cause drug-independent DIIHA that can be serologically indistinguishable from warm AIHA while others can only be detected in vitro in the presence of the drug or its metabolites (drug-dependent DIIHA). Patients can present within hours of exposure to drug with severe complement- mediated intravascular
