Short-term effects of the vagal stimulation in patients with coronary disease.

INTERVENTION: 1.The patient must be in the right lateral decubitus position. 2.The patient will be asked to breathe deeply using their diaphragm for 2 minutes prior to the lymphatic pump rib cage compression. 3. The compression of the rib cage is the procedure that will be used to create a lymphatic pump; this compression is achieved manually by a physiotherapist and there is only one technique: thoracic and abdominal lymphatic pump technique. 4.We will check the level of saliva in the mouth by testing for the salivary secretion rate. 5.For vagus nerve stimulation to be possible, we need diaphragmatic breathing and to have sufficient salivary secretion in his mouth whilst the thoracic and abdominal lymphatic pump technique is being performed. Treatment sessions: 12 sessions delivered 2 per week over 6 weeks. Each treatment session lasts 10 minutes. We will administer 5 rib cage compressions repeated for 5 respiratory cycles. We will determine if there has been vagal stimulation if, during the lymphatic pump via rib cage compression, the salivary secretion in the mouth has increased. Lymphatic pump techniques and vagal stimulation are carried out in addition to the standard care rehabilitation protocol recommended by cardiologists
