the effect of combined upper and lower extremity endurance training in patients with icd

Conditions: Heart Failure With Reduced Ejection Fraction

Summary: it was aimed to examine whether the arm endurance exercise training is effective in addition to the lower cycling training program in order to alleviate the negative functional results in heart failure patients with icd.

pacemaker (permanent battery) is implanted in patients for many reasons. for reasons such as symptomatic bradycardia and av block, a pacemaker with modes such as vvr and dddr designed for pacing only when the pulse decreases can be implanted. at the same time, pacemakers can be implanted in vr-icd, dr-icd modes, which have the ability to recognize fatal rhythm problems such as ventricular tachycardia (vt) / ventricular fibrillation (vf) and perform intracardiac defibrillation (icd). pacemakers are positioned by opening a pocket under the patient's left pectoral muscle.cables coming out of the battery (leads) are placed in the right ventricle, right atrium or coronary sinuses via active or passive fixation through the left subclavian vein. in the early period after pacemaker implantation, patients are warned to avoid movements that force the extremity on that side so that the leads and battery are affected by extremity movements and their positions and functions are not impaired. many pacemaker patients prolong this period too much (\> 3 months), causing them to develop left extremity muscle-joint dysfunction. this situation can also affect the functional capacity of the patients.icd pacemakers are larger in size than conventional pacemakers due to their functions, so they are placed in a larger pocket in the pectoral area.these patients are warned more strictly about coercive movements. the aim of this study is to investigate the effect of arm ergometer endurance training on functional capacity and upper extremity function in heart failure patients with icd included in cardiac rehabilitation program, and to examine the effect on battery and leads as safety parameters.

Eligibility criteria:
