  • P Wave Deflection

    wave, any abnormalities and how every waveform and parts of the body rely on one another to work properly. There are five waveforms: P wave, Q wave, R wave, S wave and T wave. The P wave is the SA node and it is the main starter of the electrical conduction of the heart. This wave is the first thing that is seen on the ECG sheet and shows the atrial depolarization. The Q wave is the downward deflection following the P wave and sometimes it can be seen other times it cannot.…

  • Heart Conduction System Essay

    Conduction System of the Heart What makes the heart beat? Your heart continues beating every moment of the day and night, even without you being aware of it. It may change its rate and rhythm for a few moments when you exercise or when you are excited, but it soon goes back to its regular pace without your conscious control. The cycle of contraction and relaxation of the heart muscle is generated by electrical impulses that are controlled by the conduction system of the heart, which may be…

  • Electrical Impulses

    3. Explain the heart generates and conducts an electrical current. Page 388 The heart has its own built-in conduction system for generating action potentials spontaneously and coordinating contractions during the cardiac cycle. All the cardiac muscle fibers in each region of the heart are electrically linked together. The intercalated disks are connections that electrically join the muscle fibers of the heart into a single unit that can conduct electrical impulses through the entire wall of…

  • Cardiac Conduction System Of The Heart Case Study

    Que: 1 Describes the components and conduction pathway of the cardiac conduction system of the heart.relate the cardiac condution system to the corresponding sequence of heart chamber contractions. The cardiac conduction system refers to a group of specialized muscle cells of the heart’s wall (Assadi, 2013). The cells are meant to send signals to the cardiac muscles thus contraction. The major components of the cardiac conduction system are the Atrioventricular node, sinuatrial node, the bundle…

  • Cardiac Arhythmia Case Study

    Cardiac Arrhythmia is an anomaly in the Heart which can be diagnosed with the help of Electrocardiogram (ECG) signal. ECG signal is a diagrammatic representation of the cardiac signal, which is most important biomedical signal, taken for the feature extraction. Since it is very difficult to analyse the ECG signal due to the size, noise and changes in the signal, automatic system for ECG signal processing is essential. For this, ECG signal is processed using wavelets based signal processing,…

  • Ventricles Case Study

    and left ventricle. This happen is due to inefficient cycle of blood resulting in abnormal heart sound or heart murmur. Mitral valve of the left side is misshape and less flexible. Mitral valve has a leakage and allows blood to backflow into the atrium when ventricle contracted. This condition can be the result of valvular insufficiency. This occurs when one of the heart valve leaks because the cusps do not close tightly enough. It can caused by inflammation in the heart…

  • Intrinsic Conduction System: A Case Study

    Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446). • Within the capillary, the oxygen molecule that is taken by the red…

  • Red Blood Cell Case Study

    Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. The path of a RBC consist of it first beginning in the heart as the RBC transports oxygen into the aorta by the aortic valve through contracting of the left ventricle. From the aorta, the RBC then travels through an artery with the help of arterioles to reach the capillaries. When in the capillary, the oxygen molecule that is carried by the RBC then detaches and travels through the capillary into…

  • Frog Lab Report

    1. Yes. The heart of the frog contracts and relaxes rhythmically. This behaviour is shown by the observation of the general fluctuations in the force values as well as the consistent patterns of the ECG which occurs in regular intervals. 2. This delay is primarily caused by the atrioventricular node (A-V node) and the adjacent conductive fibres. Conduction in cardiac muscle is hindered by the decreasing number of gap junctions along the pathway of conduction which creates a resistance…

  • Circulatory System Research Paper

    The circulatory system is the system that transports nutrients, oxygen, carbon dioxide, hormone. It also helps fight disease, maintain body temperature, pH, and homeostasis. There are two systems that make up the circulatory system which are the cardiovascular system and the lymphatic system. The circulatory system moves blood through the body and is made up of the heart, blood vessels and the blood. The lymphatic system moves lymph to various parts of the body and is formed by the lymph, lymph…
