Assignment 1: illustrate normal ECG curve (waves, segment and intervals).
In addressing the physiology assignment concerning the illustration of a normal ECG curve, I drew upon my medical training to provide a thorough explanation. Utilizing my knowledge of cardiovascular physiology, I outlined the key components of the ECG, including the P wave, QRS complex, and T wave, as well as the PR interval, QRS duration, and QT interval. Employing diagrams and visual aids, I meticulously depicted each waveform, segment, and interval, ensuring accuracy and clarity in my illustration. Additionally, I referenced reputable sources and textbooks to enhance my understanding and ensure the accuracy of my depiction. This approach aimed to demonstrate my proficiency in interpreting and illustrating ECG findings while showcasing a deep understanding of cardiovascular biochemistry to my professor.
Assignment 2: compare between Ventricular action potential and pacemaker potential (illustrate by curves).
In addressing the biochemistry assignment comparing ventricular action potential and pacemaker potential, I approached the task with a focus on elucidating the differences between the two phenomena. Firstly, I outlined the distinct characteristics of each potential type. Ventricular action potential, characterized by a rapid depolarization phase followed by a plateau phase and repolarization, corresponds to the electrical activity of ventricular myocytes during contraction. In contrast, pacemaker potential exhibits a gradual depolarization phase, driven by a combination of inward sodium and calcium currents, followed by repolarization. Secondly, I illustrated these differences graphically, utilizing curves to visually represent the temporal changes in membrane potential associated with each type of potential. By juxtaposing these curves, I aimed to provide a clear and concise comparison, facilitating a deeper understanding of the underlying biochemistry of cardiac electrical activity.
