Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and
mortality, and its incidence has grown within several years, quickly becoming the third …

BACKGROUND Early identification of patients at risk of congestive heart failure (HF) may
alter their poor prognosis. The aim was therefore to test whether simple electrocardiographic …

Background: Pulmonary hypertension (PH) can cause characteristic electrocardiographic
(ECG) changes due to right ventricular hypertrophy and/or strain. The aims of the present …

Abstract Background Pectus excavatum (PEx) can cause cardiopulmonary limitations due to
cardiac compression and displacement. There is limited data on electrocardiogram (ECG) …

The hyperproliferation of pulmonary arterial smooth muscle cells (PASMCs) plays a pivotal
role in pulmonary arterial remodeling (PAR) of hypoxia-induced pulmonary hypertension …

Introduction The role that preprocedural factors have on atrioventricular synchrony (AVS)
provided by leadless pacemakers requires investigation. Methods and Results We aimed to …

Aims Pulmonary hypertension (PH) is a serious disorder that can complicate pulmonary and
cardiovascular diseases. Right atrial (RA) pressure is a robust predictor of the pulmonary …

Objective: This study aims to characterize P and Ta wave of Modified Limb Lead (MLL)
Electrocardiogram (ECG) in Normal Sinus Rhythm (NSR) and Atrioventricular Block (AVB) …

Hypertension and chronic obstructive pulmonary disease are one of the frequent comorbid
conditions in internal medicine and are subject to meaningful cooperation among …

Background: Right atrium (RA) enlargement in uncorrected atrial septal defect (ASD) is due
to chronic volume overload. Several electrocardiogram (ECG) criteria had been proposed …
