Intravenous propafenone and verapamil cardioversion of paroxysmal supraventricular tachycardia observation on the effects
In favor of propafenone after cardioversion (P 0.05). 2.3 l of drug side effects of propafenone group after drug cases because of a QRS prolongation of 25% over the termination of the original trial, verapamil group 2 patients in the bolus injection of drugs, blood pressure less than 90 / 60mmUs termination test. 3 to discuss the group test propafenone PSVT cardioversion success rate was 96.4%, consistent with the reported results】. Propafenone is a class Ic antiarrhythmic drugs. Experiments confirmed that b】, propafenone can inhibit the myocardial cells induced delayed afterdepolarization amplitude, slow delayed after depolarization and the extension of the ascending branch of delay after the rising rate of the heart than Kerry button, a senior engineer. Pole coupling interval, thereby inhibiting the trigger activity. Which extend the effective refractory period and functional myocardial refractory period, slowing heart self-discipline, and can slow conduction of the bypass, it can be used for PSVT, including the pre-shock syndrome caused by PSVT. The group, 4 cases were ineffective with verapamil and atypical atrial tachycardia patients, all after the switch to re-use of propafenone success. Alone in terms of atrial tachycardia cardioversion, propafenone is superior to verapamil. PSVT in the complex process of transfer, propafenone rapid onset, fewer side effects, is a safe and effective drug. Verapamil belongs to Tv class antiarrhythmic agents. Its L-type calcium channel blocking effect of J, inhibition of myocardial delayed afterdepolarizations and triggered electrical activity, thus reducing the myocardial cells induced delayed afterdepolarization amplitude, slow down the ascending branch of delayed after depolarization increased rate and lowered after prolonged delay pole coupling interval. Showed prolongation of effective refractory period and functional refractory period, slowing of atrioventricular junction excited in the downstream,[link widoczny dla zalogowanych], but will also slow down the conduction of the bypass. Can be used in a typical pre-shock syndrome caused by PVST and the PSVT. Verapamil treatment for PsVT, the effect is clear, fewer side effects. However,[link widoczny dla zalogowanych], due to increased self-regulation due to atrial supraventricular tachycardia and atypical (excitement along the fast track to download and upload by the slow channel) supraventricular tachycardia, as effective as propafenone. 4 patients in this group of first use of verapamil is not valid,[link widoczny dla zalogowanych], the switch to turn propafenone after supraventricular tachycardia to sinus rhythm, is the example. In this study,[link widoczny dla zalogowanych], the transfer of complex PSVT, propafenone cardioversion cardioversion rate and time are better than verapamil,[link widoczny dla zalogowanych], but not statistically significant. Increased self-regulation of the heart caused by supraventricular tachycardia and atypical PSVT, propafenone cardioversion efficacy was significantly higher than verapamil. Therefore, if from the ECG can not identify the type of PSvT recommended preferred propafenone. 【
