A comparative study between normal electrocardiogram signal and those of some cardiac arrhythmias based on McSharry mathematical model.

Australas Phys Eng Sci Med 2019 Apr 2. Epub 2019 Apr 2.

University of Dschang, LISIE/L2MSP, P.O. Box 134, Bandjoun, Cameroon.

In this paper, synthetic electrocardiogram signals (SECG) of eight cardiac arrhythmias (sinus bradycardia, junctional bradycardia, tachycardia, flutter, atrial extrasystole, ventricular extrasystole, left branch block and right branch block) are obtained numerically by solving the McSharry mathematical model (2003) based on three coupled ordinary differential equations with the fourth-order Runge-Kutta method. They are compared with normal electrocardiogram signal. Indeed, visual analysis of a section of electrocardiogram (ECG) signals of these arrhythmias was used to suggest suitable values for the parameters in the McSharry mathematical model. Read More

Differential Effectiveness of Landiolol Between Atrial Fibrillation and Atrial Flutter/Atrial Tachycardia Patients With Left Ventricular Dysfunction.

Circ J 2019 Mar 28;83(4):793-800. Epub 2019 Feb 28.

Department of Cardiovascular Medicine, Nippon Medical School.

Background: Landiolol, an ultra-short acting β-selective blocker, is more effective for controlling the heart rate (HR) than digoxin in patients with atrial tachyarrhythmias and left ventricular (LV) dysfunction. The impact of the type of atrial tachyarrhythmias on the effectiveness of landiolol is uncertain. We evaluated the efficacy and safety of landiolol on tachycardiac atrial fibrillation (AF) and tachycardiac atrial flutter/atrial tachycardia (AFl/AT) in patients with reduced LV function. Read More
