1. Dysrhythmias cause serious electrolyte imbalances; this results in heart block. 2. Dysrhythmias are the result of long-standing, uncontrolled hypertension. 3. Dysrhythmias interrupt the normal electrical pathways in the heart so it can't beat properly. 4. Dysrhythmias alter the blood flow through the heart and cause it to stop beating.
Antiarrhythmic drugs are used to correct or reduce the risk of cardiac arrhythmias (dysrhythmias). They are classified into several categories.
quot;Dysrhythmias interrupt the normal electrical pathways in the heart so it can 039;t beat properly. quot; quot;Dysrhythmias alter the blood flow through the heart and cause it to stop beating. quot; Answer: 3 Explanation: Some dysrhythmias may result in heart block, but dysrhythmias do not cause electrolyte imbalances.
Dysrhythmias–slows ventricular rate in atrial fibrillation and atrial flutter; Dysrhythmias–after adenosine, 2nd line drug for refractory SVT (narrow QRS
Study with Quizlet and memorize flashcards containing terms like Dysrhythmias, Dysrhythmias Sx, Type of dysrhythmias: Atrial or ventricular flutter or fibrillation and more.
Class IA antidysrhythmics like quinidine, are used for atrial and ventricular dysrhythmias, as well as supraventricular dysrhythmias; whereas class IB antidysrhythmics, such as lidocaine, are used for acute ventricular dysrhythmias; and class IC antidysrhythmics, like flecainide, are used to treat the most serious, life-threatening ventricular
Atrial dysrhythmias. Atrial dysrhythmias include atrial fibrillation, atrial flutter, premature atrial complexes, and supraventricular tachycardia. Atrial dysrhythmia risk factors. Risk factors for atrial dysrhythmias in general include heart disease, cardiac surgery, increased age, and diabetes. Atrial Fibrillation (AFIB)
Drugs of choice for ventricular dysrhythmias are also effective for automatic and reentrant arrhythmias and digitalis-induced dysrhythmias. These drugs may aggravate myocardial depression. Class Ic: flecainide (Tambocor), propafenone (Rythmol), encainide (Enkaid)
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. cardiac dysrhythmia).
