Boloor. PATIENT IN AVRT: EKG. DELTA WAVE: . SA node triggers, sends signal to AV node and accessory pathway. AV node has a safeguard to slow the signal down so the ventricles can fill. Accessory pathway doesn’t have safeguard, meaning the signal can very quickly travel from the atria down, depolarizing the ventricles. This creates a slurred upstroke, as the P wave is closely coupled with the QRS. Once the signal gets through the AV node, it travels very quickly through the circuit of the heart and up the accessory pathway, creating a sharp downwards wave as the ventricles depolarize. . transduction can alter cellular response.. SP 1.5. : The student can . reexpress. key elements of natural phenomena across representations in the Domain . Explanation. : A signal transduction pathway is where signal transduction occurs. Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. Receptor then causes a chain of event with in the cell, causing a cellular response. Signal transduction pathways can be altered. Signal transduction pathways can be blocked by the use of drugs such as antihistamines. Also signal transduction pathways being blocked can act as a preventative against diseases. A more specific impact of drugs altering cellular response is antihistamines. This changing signal transduction is how the antihistamines block transduction by blocking the histamine that is released by the cells immune system. When a foreign antigen binds to the .
