It is well-known that not only peripheral muscles, but also respiratory muscles muscle weakness and deconditioning play an important role in low exercise capacity of patients with Heart Failure (HF). Exercise training has been shown to improve exercise tolerance and quality of life in patients with heart disease. However, hearth failure patients with pacemaker such as implantable cardioverter defibrillators (ICDs), cardiac resynchronization pacemakers or defibrillators (CRT-P or CRT-D) have additional specific issues when performing exercise. No study investigated the effects of different inspiratory muscle training protocols. For this reason, we aimed to investigate the effects of inspiratory muscle training on outcomes in hearth failure patients with pacemaker
Heart failure patients with pacemaker will be included. Primary outcome measurement is respiratory muscle strength, secondary outcomes are functional exercise capacity, peripheral muscle strength, pulmonary functions, maximal exercise capacity, fatigue, quality of life, depression, physical activity.

Treatment group will receive inspiratory muscle training (IMT) using threshold loading device (POWERbreathe Classic, IMT Technologies Ltd. Birmingham, England) at 50% of maximal inspiratory pressure (MIP). The MIP will be measured at supervised session each week, and 50% of measured MIP value will be the new training workload. The treatment group will train for 30 min-per/day, 7 days/week, for 8 weeks. Six sessions at home and 1 session will be performed at department.
Treatment group II will receive inspiratory muscle endurance training (IMT) using threshold loading device (POWERbreathe Classic, IMT Technologies Ltd. Birmingham, England) at 30% of maximal inspiratory pressure (MIP). The MIP will be measured at supervised session each week, and 30% of measured MIP value will be the new training workload. The treatment group will train for 30 min-per/day, 7 days/week, for 8 weeks. Six sessions at home and 1 session will be performed at department.

Fatigue
Fatigue Severity Scale (FSS) (Turkish version of scale) Patient choose a number from 1 to 7 that indicates how much the patient agrees with each statement, where 1 indicates strong disagreement and 7 indicates strong agreement. A score of 4 or higher generally indicates severe fatigue
Time frame: Second day
Quality of life
Short Form (SF-36) Health Survey (Turkish version of scale) The SF-36 is a 36 item questionnaire that measures eight multi-item dimensions of health: physical functioning (10 items) social functioning (2 items) role limitations due to physical problems (4 items), role limitations due to emotional problems (3 items), mental health (5 items), energy/vitality (4 items), pain (2 items), and general health perception (5 items). For each dimension item scores are coded, summed, and transformed on to a scale from 0 (worst possible health state measured by the questionnaire) to 100 (best possible health state).
Time frame: Second day
Depression
Montgomery Asberg Depression Rating Scale (MADRS) (Turkish version of scale) This assessment tool contains 10 items with a score from 0 to 6, thus the maximum score is 60. A higher score indicates a more severe depression.
Time frame: Second day
Physical activity
International Physical Activity Questionnaire (IPAQ) - Short Form (Turkish version of scale ) This questionnaire assesses, in minutes, the physical activity performed by the volunteers during the period of one week. The IPAQ considered all activities carried out by the volunteer (e.g. leisure, sport, exercise, and activities at home or in the garden). According to the responses, the volunteer is considered very active, active, irregularly active or sedentary, according to the intensity and time of the exercises practiced over the last week.
Time frame: Second day
Health-related quality of life
Minnesota Living with Heart Failure Questionnaire (MLHFQ) (Turkish version of scale) 21 items rated on six-point Likert scales, representing different degrees of impact of HF on Heart Related Quality of Life (HRQoL), from 0 (none) to 5 (very much). It provides a total score (range 0-105, from best to worst HRQoL), as well as scores for two dimensions, physical (8 items, range 0-40) and emotional (5 items, range 0-25).
Time frame: Second day
Cognitive function
Mini mental state examination (MMSE)(Turkish version of scale ) The scale has a maximum score of 30 points. The questions have been grouped into seven categories, each rationally representing a different cognitive domain or function: Orientation to time (5 points); Orientation to place (5 points); Registration of three words (3 points); Attention and Calculation (5 points); Recall of three words (3 points); Language (8 points) and Visual Construction (1 point). The severity of cognitive impairment is classified as normal (30-27) mild cognitive impairment (26-20); moderate cognitive impairment (19-10); and severe cognitive impairment(\< 10).
Time frame: First day
Functional exercise capacity
6 minute walking test
Time frame: Second day
