Specific conditions that fall under the definition of atrial tachyarrhythmias are atrial fibrillation, atrial flutter, multifocal atrial tachycardia, paroxysmal supraventricular tachycardia, and so on. [34] [35] [36] Verapamil is also a Kv voltage gated potassium channel blocker. [37]
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]
Side effects of these drugs may include but are not limited to: Constipation; Peripheral edema, which can occur in as much as 70% of people receiving calcium channel blocker, is caused by calcium channel blockers' preferential arteriolar or precapillary dilation without commensurate dilation in the venous or postcapillary circulation.
Cardiovascular agents generally have narrow therapeutic indices, implying that small differences in dose or blood concentration may give rise to adverse drug reactions. [45] Serious acute toxicity may result from accidental, intentional or iatrogenic overdose. [46] Therefore, patients need to be aware of any unusual and serious side effects.
Other potential symptoms include: nausea and vomiting, a decreased level of consciousness, and breathing difficulties. [2] Symptoms usually begin within 6 hours of taking the medication by mouth. [2] With extended release formulations symptoms may not occur for up to a day. [2] Seizures are rare in adults but in children occur more often. [2]
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 ...
Ectopic atrial tachycardia (EAT), also known as automatic atrial tachycardia, is an arrhythmia caused by both atria with abnormally fast atrial rates. [12] The ectopic focus's firing rate is quicker than that of the sinus node, and it overrides normal sinus node activity. Heart rates in children and adolescents can range from 130 to 210 beats ...
