Ventricular flutter

Impulses originating at loci outside the sinus node are seen in supraventricular or ventricular extrasystoles, tachycardia, atrial or ventricular flutter, and fibrillation. In these forms of rhythm disorders, antiarrhythmics of the local anesthet-Ltillmann, Color Atlas of Pharmacology... 

Disturbances of cardiac rhythm (e.g., tachycardia, atrial fibrillation, ventricular flutter, and A-V or intraventricular block) are the most frequent causes of death. Thus, management of cardiac function is critical. If the patient survives the early phase, recovery without sequelae is probable, and vigorous resuscitative measures are important. A major clinical problem is determining when a patient is no longer in danger. Many patients with mild overdose have been hospitalized... 

An 8-year-old girl had an insulin tolerance test with 0.05IU/kg to assess growth hormone concentrations. The blood glucose concentration fell to 0.9 mmol/1 and she was given intravenous dextrose. She had a generalized seizure and developed ventricular flutter. 

After an overdose of detajmium bitartrate in a dose of 18 mg/kg, a 36-year-old woman developed ventricular flutter, which responded to treatment with lidocaine, defibrillation, glucagon, noradrenaline, and sodium chloride (17). Hjrpokalemia responded to intravenous potassium chloride. 

Dysrhythmias can occur these include ventricular tachycardia, ventricular flutter, and atrial fibrillation (19-21). Hypotension and worsening of heart failure have occasionally been reported (SEDA-10,151) (22).

Lethal intoxication with yew leaves (T. baccata) presented with dizziness 1 hour after ingestion, nausea, diffuse abdominal pain, unconsciousness, weak breathing, tachycardia, brief ventricular flutter followed by bradycardia, and finally death by respiratory arrest and cardiac standstill the electrocardiogram showed atypical bundle branch block and absent P waves (10). 

Ventricular flutter fibrillation V entricular flutter fibrillations with ventricular contractions of 180-250 beats/minute cause sudden death. There are no coordinated contractions, resulting in loss of blood pressure and pulse. Unconsciousness and respiratory arrest follow. The usual cause is coronary arterial disease (i.e., myocardial infarction). 

The major component of the antiarrhythmic mechanism of a (3-blocker undoubtedly is the termination or prevention of those tachyarrhythmias caused by excess sympathetic tone, which may in turn be the result of increased circulating catecholamines. The control of ventricular flutter that is not effectively controlled with digitalis therapy alone can also be achieved by the addition of (3-blockers since they prolong the AV refractory period. 

Gastrointestinal stimulants should not be used for patients who have cardiac dysrhythmias especially ventricular tachycardia, ventricular flutter, or fibrillation.

May be difficult to distinguish the relatively rare torsades de pointes from ventricular flutter. 

Ventricular flutter, although rarely recognized, results from the rapid, regular, repetitive beating of the ventricles. It s produced by a single ventricular focus firing at a rapid rate of 250 to 350 beats/minute. The hallmark of this arrhythmia is its smooth sine-wave appearance.
