These features may provide therapeutic benefits, for example, a less pronounced increase in sympathetic tone and reflex tachycardia, and reduced likelihood of negative inotropic effects. These agents can therefore probably be used in patients with left ventricular dysfunction. 展开 ...
(d) calcium infusion: 0.4 mL/kg/hour of calcium chloride or 1.2 mL/kg/hour of calcium gluconate; (e) glucagon infusion: 2–10 mg/hour (50–100 μg/kg/h); and (f) dextrose infusion: 5 mL/kg/hour of D10W or 2 mL/kg/hour of D25W (solutions that are >10% ...
Verapamil is the most potent inhibitor of cardiac conduction and contractility, with diltiazem also showing such effects. Nifedipine is the most potent vasodilator, but only occasionally impairs the sinus node or AV conduction. Significant pharmacodynamic effects are common during combination therapy with ...
in each class. Diltiazem and especially verapamil tend to produce the most hypotension, bradycardia, conduction disturbances and deaths of the CCB. Nifedipine and other dihydropyridines are generally less lethal and tend to produce sinus tachycardia instead of bradycardia with fewer conduction disturbances...
(ii) calcium gluconate: 30–60 mL of a 10% solution (dose can be repeated if no effect); (iii) continuous infusion with either salt: 0.5 meq of Ca/kg/hr; (b) glucagon: 5 mg IV bolus, can be repeated twice at 10 min intervals. ...
verapamil and diltiazem interrupt the reentry circuit in supraventricular tachycardias and are useful in terminating those arrhythmias. They are also effective in slowing the ventricular response in atrial fibrillation (AF) and may be used in chronic AF; the DHPs are ineffective for these arrh...
The patient received intravenous boluses of calcium gluconate for correction. The patient had bradycardia during the first calcium gluconate infusion, and on the second infusion, he developed frequent premature ventricular contractions, which progressed into polymorphic ventricular tachycardia. Arrhythmia ...
