A comparison of the effects of inspiratory muscle strength and endurance training on exercise capacity, respiratory muscle strength and endurance, and quality of life in pacemaker patients with heart failure: A randomized study

•IMST and IMET similarly improve respiratory muscle strength and endurance.•IMST and IMET similarly improve peripheral muscle strength, exercise capacity, PA level, and QoL•IMST and IMET similarly alleviate dyspnea and fatigue.•IMST and IMET are safe and effective methods in pacemaker patients with HF.
