Prevent paroxysmal atrial fibrillation [7] and haemodynamically stable ventricular tachycardia [8] (amiodarone) Treat atrial flutter and atrial fibrillation (ibutilide) Treat ventricular tachycardia and atrial fibrillation (sotalol) Treat Wolff-Parkinson-White syndrome; IV Calcium channel blockers Diltiazem; Verapamil; Ca 2+ channel blocker
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
For supraventricular tachycardias , diltiazem appears to be as effective as verapamil in treating re-entrant supraventricular tachycardia. [17] Atrial fibrillation [18] or atrial flutter is another indication. The initial bolus should be 0.25 mg/kg, intravenous (IV). Because of its vasodilatory effects, diltiazem is useful for treating ...
Verapamil is a class-IV antiarrhythmic and more effective than digoxin in controlling ventricular rate. [19] Verapamil is not listed as a first line antihypertensive agent by the guidelines provided by JAMA in JNC-8. [20] However, it may be used to treat hypertension if patient has co-morbid atrial fibrillation or other types of arrhythmia. [17 ...
Put down the holiday drink and take care of the heart with new guidelines on Afib.
Afib symptoms. Most people in Afib experience signs that something is amiss, including: Feeling more fatigued. Having decreased energy levels. Experiencing heart palpitations or fluttering in ...
Drugs like amiodarone, diltiazem, verapamil and metoprolol are frequently given before electrical cardioversion to decrease the heart rate, stabilize the patient and increase the chance that cardioversion is successful. There are various classes of agents that are most effective for pharmacological cardioversion.
The negative chronotropic effects of CCBs make them a commonly used class of agents in individuals with atrial fibrillation or flutter in whom control of the heart rate is generally a goal. Negative chronotropy can be beneficial when treating a variety of disease processes because lower heart rates represent lower cardiac oxygen requirements.
