Izmir Democracy University52 enrolled

Overview

Premature ventricular complexes may be observed in individuals without underlying disease due to factors such as physical inactivity, advanced age, smoking, male sex, and psychosocial disturbances, and in some cases may result in sudden cardiac death. Therefore, the aim of this study is to investigate respiratory function, respiratory muscle strength, cough strength, handgrip strength, physical activity level, and quality of life in individuals with premature ventricular complexes.

The primary aim of this study is to comprehensively investigate respiratory function, respiratory muscle strength, cough strength, handgrip strength, physical activity level, and quality of life in individuals with premature ventricular complexes. Additionally, an important secondary aim is to identify potential differences in these parameters between individuals with premature ventricular complexes and healthy controls and to contribute original findings to the existing literature.Participants will be evaluated in terms of these parameters through clinical assessments, questionnaires, and measurements.

Interventions

Physical Evaluations of Patients with Premature Ventricular ComplexOTHER

In this study, data from individuals with premature ventricular complex will be collected through face-to-face assessments. Respiratory functions, respiratory and peripheral muscle strength, cough strength, physical activity level, and quality of life will be assessed in these individuals who meet the inclusion criteria. All data obtained through these assessments will be collected from participants face-to-face at one time and for a maximum of approximately 1 hour.

Physical Evaluations of Healthy IndividualsOTHER

In this study, data from healthy individuals will be collected through face-to-face assessments. Respiratory functions, respiratory and peripheral muscle strength, cough strength, physical activity level, and quality of life will be assessed in these individuals who meet the inclusion criteria.All data obtained through these assessments will be collected from participants face-to-face at one time and for a maximum of approximately 1 hour.

Outcomes

Primary Outcomes

Maximal inspiratory pressure (MIP)

The MIP which shows respiratory muscle strength will be evaluated using a portable mouth pressure measuring device based on American Thoracic Society and European Respiratory Society criteria.
