Disease relevance of Tachycardia, Paroxysmal

• Polyuria during paroxysmal tachycardia was attributed mainly to the inhibition of arginine vasopressin release [1].
• A comparison of verapamil with adenosine for the immediate treatment of supraventricular tachycardia was made from a retrospective review of 164 spontaneous episodes of paroxysmal tachycardia in 43 patients [2].

High impact information on Tachycardia, Paroxysmal

• Periodic procainamide for paroxysmal tachycardia [3].
• Effects of quinidine on atrioventricular nodal reentrant paroxysmal tachycardia [4].
• Flecainide acetate, a new class 1 agent, was therefore administered both intravenously and orally to 13 patients with recurrent paroxysmal tachycardia to assess whether the acute response to intravenous flecainide accurately predicts the response to oral therapy [5].
• Intravenous moricizine HCl terminated atrioventricular nodal reentrant paroxysmal tachycardia in 66% of patients, whereas 40% responded to the oral drug [6].
• Intrauterine digoxin treatment of fetal paroxysmal tachycardia. Case report [7].

Chemical compound and disease context of Tachycardia, Paroxysmal

• The effect of intravenous disopyramide phosphate on recurrent paroxysmal tachycardias [8].
• The acute electrophysiologic effects of 10 mg bisoprolol (B, given intravenously) were evaluated during an electrophysiological study in 10 patients with a history of paroxysmal tachycardia [9].
• Transesophageal atrial pacing was performed at rest and during infusion of isoproterenol in 31 children or adolescents aged 9-19 years (16 +/- 3 years) with normal sinus rhythm ECG and suspected or documented episodes of paroxysmal tachycardia [10].
• Acute treatment of paroxysmal tachycardia by adenosine [11].
• Clinical antiarrhythmic effects of amiodarone in patients with resistant paroxysmal tachycardias [12].

Biological context of Tachycardia, Paroxysmal

• This phenomenon was studied in 14 patients, with a history of supraventricular paroxysmal tachycardia, at the patient's own heart rate, at different paced heart rates, and after the administration of atropine [13].
• In an attempt to define more clearly the hemodynamic effects of paroxysmal tachycardia in their time sequence not only for the normal heart, we monitored coronary sinus flow (CSF), aortic mean pressure (AOMP), and coronary vascular resistance in 42 patients [14].

Gene context of Tachycardia, Paroxysmal

• These results suggest that hANP released by paroxysmal tachycardia might not act as a natriuretic factor in this range of plasma concentration [1].
• This study suggests that: 1) HC-PE association is not infrequent; 2) the incidence of paroxysmal tachycardias in the subgroup is quite similar to that presented in isolated PE; and 3) the electrocardiographic and vectorcardiographic changes in the HC-WPW type of PE association are highly specific [15].

Analytical, diagnostic and therapeutic context of Tachycardia, Paroxysmal

• Electrophysiologic studies were performed in 14 patients with atrioventricular nodal reentrant paroxysmal tachycardia (PSVT) before and after oral administration of 1.2-1.6 g quinidine sulfate over a 24-hour period (0.3-0.4 g every 6 hours) [4].
