Study of a case of "pacemaker syndrome" by echocardiography and phonomechanocardiography

Acta Cardiologica
D Soyeur

Abstract

This report is concerned with the observation of a woman aged 61 with sino-atrial disorders in whom near-syncopal episodes recurred after implantation of a pacemaker. The attacks were associated with paroxysmal lowering of blood pressure. The echocardiogram and the phonomecanocardiogram indicated that a shortening of the left ventricular ejection time and a decrease of the duration and the amplitude of the separation of the aortic valve leaflets abruptly appeared whenever the patient was under pacing. This data further stresses the importance of the so-called "pacemaker syndrome". The phonomecano- and echocardiogram may permit to select among paced patients with recurrent symptoms those who deserve consideration of replacement of their ventricular pacemaker by a bifocal unit.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
