146. An unstable wide complex tachycardia resistant to electrical cardioversion

would have taken him to cath lab for temporary pacemaker and 'pace-termination' before considering procainamide (of course depending on hemodynamics at the moment)." -- Procainamide may work if the above do not, but is especially hazardous with decreased LV function and should be given very slowly, if at all. Give 20 mg/min to a total of 15 mg/kg until the arrhythmia terminates, the BP drops, or the QRS is prolonged by more than 50%. Procainamide slows the VT rate and though it often causes (...) like amiodarone, it is relatively contraindicated. And you can't measure the QT while the patient is still in VT!

If no conversion, or if reversion, use amiodarone 5. If amio does not work, try lidocaine 6. Consider beta blockade. 7. Consider pacing termination 8.

be anywhere between 240 and 360. The ventricular rate depends on AV node conduction and is usually half the atrial rate (2:1 conduction), but may become 1:1 (dangerous) or slow down to less than 2:1 in the presence of AV node blockers The atrial rate can be much slower in the setting of a sodium channel blocker such as flecainide, quinidine, or procainamide. Use of these medications without prior AV blockade is dangerous as it will lead to 1:1 conduction!! Atrial Flutter --Macro re-entrant loop just above (...)

the ventricular rate of Aflutter with an agent like procainamide? It is ONLY in flutter that a rhythm control drug can paradoxically increase the ventricular rate. Is that what you are referring to? Would performing a Lewis Lead show the atrial activity more clearly? Lewis leads show sinus P-wave more clearly. Uncertain if they will show these flutter waves more clearly because the recording appears to already be at the optimal angle for highest possible amplitude. Dear colleague Could it be the same case

Ibutilide is also listed with the same level of recommendation in our guidelines (Class I, Level C-LD: very low level of evidence, but supposedly more than just expert opinion), but unless I'm mistaken this drug is more expensive and less commonly used. Electricity is clearly not going to be effective long term if the rhythm is re

151. Wide complex tachycardia at a rate of 270

, increased sympathetic tone also increases AV conduction (makes it more "slick," or "greasy"). This could counteract the faster atrial rate and prevent the slowing of the ventricular rate. Why is this concept important for us? If you see a patient with atrial flutter with 2:1 conduction and you want to convert the atrial flutter chemically with, for instance, procainamide (or any other type 1 antidysrhythmic), you could convert to 1:1 conduction. How? Procainamide is used to convert flutter to sinus (...) , but before conversion (or if it is ineffective), it will cause the atrial flutter rate to slow to a rate that makes 1:1 AV conduction possible. You will have made the situation worse. Therefore : If you ever want to convert atrial flutter by giving procainamide or any other Type 1 antidysrhythmic, you MUST give an AV nodal blocker first , or you will make the patient worse. I always use electricity to convert atrial flutter. It is safer. Similarly : Any patient who is started on a Type 1 antidysrhythmic

with management that is based on acknowledging both possibilities simultaneously. Options for this patient with wide complex regular tachycardia and some signs of hemodynamic compromise but not peri-arrest include: Immediate attempted intervention on the rhythm: - Synchronized electrical cardioversion - Adenosine and/or vagal maneuvers - Medical cardioversion (procainamide, amiodarone, etc) These options all incur some small risk (sedation for cardioversion, very small risk of deterioration in rhythm (...) with adenosine, hypotension or rhythm deterioration with amiodarone/procainamide), while having the potential benefits of cardioversion (if the rhythm is not Sinus Tach) and further diagnostic information for the rhythm.

Dysregulation of miR-155-5p and miR-200-3p and the Anti-Non-Bilayer Phospholipid Arrangement Antibodies Favor the Development of Lupus in Three Novel Murine Lupus Models Systemic lupus erythematosus (SLE) is characterized by deregulated activation of T and B cells, autoantibody production, and consequent formation of immune complexes.

To provide guidance for the proper selection of derivatizing reagents and LC columns, herein, we describe a comprehensive assessment of 2-aminobenzamide, procainamide, aminoxyTMT, RapiFluor-MS (RFMS) labeling, reduction and reduction with permethylation for N-glycan analysis. Of the derivatization strategies examined, RFMS provided the highest MS signal enhancement for neutral glycans, while permethylation

to promote the expression of genes commonly silenced. For such finality, five filamentous fungal species (Talaromyces funiculosus, Talaromyces islandicus, Talaromyces minioluteus, Talaromyces pinophilus, Penicillium janthinellum) were grown or not with DNA methyltransferases inhibitors (procainamide or hydralazine) and/or a histone deacetylase inhibitor (suberohydroxamic acid). Extracts from T. islandicus cultured or not with hydralazine inhibited Listeria monocytogenes growth in 57.66±5.98% and 15.38 (...) ±1.99%, respectively. Increment in inhibition of acetylcholinesterase activity was observed for the extract from P. janthinellum grown with procainamide (100%), when compared to the control extract (39.62±3.76%). Similarly, inhibition of acetylcholinesterase activity increased from 20.91±3.90% (control) to 92.20±3.72% when the tested extract was obtained from T. pinophilus under a combination of suberohydroxamic acid and procainamide. Concluding, increases in antimicrobial activity
