Episode of ventricular arrhythmia; Management options include pharmacological, surgical, catheter ablation, and placement of an implantable cardioverter-defibrillator. Prior to the decision of the treatment option, programmed electrical stimulation in the electrophysiology laboratory may be performed for additional prognostic information. Goals ...
Psychological therapies for dementia are starting to gain some momentum. [ when? ] Improved clinical assessment in early stages of Alzheimer's disease and other forms of dementia , increased cognitive stimulation of the elderly, and the prescription of drugs to slow cognitive decline have resulted in increased detection in the early stages.
Childhood dementia is very often diagnosed late, misdiagnosed, or not diagnosed at all. [9] A correct diagnosis happens, on average, 2 years or more after symptoms become apparent. Additionally, children affected by childhood dementia are often misdiagnosed with: Autism [16] [9] [17] Developmental or intellectual delay [16] [9] ADHD [9] Others [9]
Since these agents do not affect the sodium channel, conduction velocity is not decreased. The prolongation of the action potential duration and refractory period, combined with the maintenance of normal conduction velocity, prevent re-entrant arrhythmias. (The re-entrant rhythm is less likely to interact with tissue that has become refractory).
Sotalol is indicated for the treatment of atrial or ventricular tachyarrhythmias, and AV re-entrant arrhythmias. Ibutilide is the only antiarrhythmic agent currently approved by the Food and Drug Administration for acute conversion of atrial fibrillation to sinus rhythm.
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
If a life-threatening arrhythmia is detected, the device can deliver a small electric shock to terminate the abnormal rhythm and restart the heart. [1] Implantable defibrillators are often recommended for those with CPVT who have experienced blackouts, ventricular arrhythmias or cardiac arrest despite taking appropriate medication. [2]
Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. [1] This is different from normal pacemaking activity, where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm. Causes of wandering atrial ...
