Abstract

The purpose of the study was to explore late ventricular potentials (LVPs) in patients with cardiological X syndrome (XS), their association with ventricular arrhythmias (VA), with the structure and function of the heart. Fifty-two patients were examined. A control group comprised 17 healthy individuals. LVPs were determined by recording a signal-averaged high resolution (AHR) ECG by means a Megacart-400 device ("Siemens"). It was shown that there was a relationship between LVPs and high-grade VA in patients with XS. The patients with the recorded LVPs were observed to have the enlarged left ventricle (LV) and a significant ST-segment depression during bicycle ergometric tests. Those with LVPs were ascertained to have a relationship between the end LV systolic volume and the values of a single of AHR ECG. At the same time, there was no correlation between the values of a single of AHR ECG and the magnitude of ST-segment depression.

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.

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.

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.
