Group of pharmaceuticals that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Type I (sodium channel blockers) Type Ia Ajmaline; Procainamide; Quinidine; Type Ib Lidocaine; Phenytoin; Type Ic Encainide; Flecainide; Propafenone; Type II (beta ...
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.
The dose is 5–10 mg/kg and side effects are high blood pressure followed by low blood pressure and ventricular ectopy. Originally introduced in 1959 for the treatment of hypertension. [2] Its use as an antiarrhythmic for ventricular fibrillation was discovered and patented by Marvin Bacaner in 1969 at the University of Minnesota. [3]
It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia, when a pulse is present. Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks referred to as defibrillation.
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Patients with hypertensive heart disease should avoid taking over the counter nonsteroidal anti-inflammatory drugs (NSAIDs), or cough suppressants, and decongestants containing sympathomimetics, unless otherwise advised by their physician as these can exacerbate hypertension and heart failure. [11] [12]
For others with more mild depression or moderate symptoms of depression, over-the-counter medication might seem like the better choice. And if you decide to explore this route, it’s never a bad ...
Torsades de pointes – A type of ventricular tachycardia with a characteristic ECG appearance that can progress to ventricular fibrillation. Ventricular fibrillation (vfib) – Fibrillation of the ventricles is a life-threatening arrhythmia and should be treated by defibrillation and is a medical emergency. Vfib results from uncoordinated ...
