Ennenaikaisissa kamransisäisissä ekstrasystoleissa esiintyvät fyysiset vammat
Tutkimus hengitystoiminnasta, lihasvoimasta, fyysisestä aktiivisuustasosta ja elämänlaadusta ennenaikaisia kammiokomplekseja sairastavilla henkilöillä
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.

Yksityiskohtainen kuvaus
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.

Ventricular premature complexes group
This group will consist of individuals with premature ventricular complex. |
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. |

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. |

|
Assessment of Physical Activity
Aikaikkuna: through study completion, an average of 1 year
|
Participants' physical activity levels over the previous seven days will be assessed using the International Physical Activity Questionnaire-Short Form. The questionnaire consists of 7 items that assess time spent walking, and moderate- and vigorous-intensity physical activities over the last seven days. Total physical activity scores will be calculated by summing the duration (minutes) and frequency (days) of walking, moderate-intensity, and vigorous-intensity activities. Total physical activity score will be expressed as metabolic equivalent task minutes per week (MET-min/week). |

|
Assessment of Quality of Life
Aikaikkuna: through study completion, an average of 1 year
|
Participants' quality of life will be evaluated using the Short Form-36 Health Survey (SF-36). The SF-36 assesses eight health domains: general health, physical functioning, role limitations due to physical problems, role limitations due to emotional problems, social functioning, bodily pain, vitality, and mental health, along with one additional item assessing health transition. Participants will be instructed to respond to each question in a manner that best reflects their current condition, and researchers will provide clarifying guidance when necessary. |
