The ventricular action potential has a long refractory period so that the mechanical response of the ventricle will be discrete; one coordinated mechanical response per electrâ¦ical activation sequence. Otherwise, with additional electrical stimuli, the mechanical responses would summate producing a prolonged contraction.
Microfracture Technique. Overview. Microfracture is a surgical technique that has been developed to treat chondral defects, which are damaged areas of articular cartilage of the knee. It is a common procedure used to treat patients with full thickness damage to the articular cartilage that goes all the way down to the bone.
Collagen Induction Therapy (CIT) is a minimally-invasive cosmetic procedure that involves the use of a micro-needling device.CIT is safe and effective on all skin types, and when properly applied, there is minimal risk of discoloration.The micro-needling procedure can be performed by licensed qualified medical professionals including physicians, osteopaths and naturopaths.IT or micro-needling stimulates a complex wound-healing mechanism. The important point is: a micro-needling intrusion is caused by tiny surgical needles. The skin's nerve receptors and defense mechanisms sense these fine needle intrusions as a specific type of injury and heals accordingly.
