To review:
The given blank space in the statement using the following ECG graph.
QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
The process by which the heart rate of a patient is recorded is known as electrocardiography (ECG). The representation of this heart rate in a graph is called electrocardiogram. The electrical changes in the heart are detected by electrodes that are placed on the skin. The graph shows various components, such as P, Q, R, S, T, and U. These graphs are seen by doctors who interpret them in a systemic approach.

- Put these steps of the control of blood pressure in the right order: ________________________ angiotensin I made by the liver ________________________ renin made by the kidney ________________________ juxtaglomerular apparatus indicates a blood pressure drop ________________________ angiotensin II made by the lungs ________________________ blood pressure rises ________________________adrenal cortex makes aldosteronearrow_forwardMatch the anatomic term in column II with its associated function in column I: Column I __________ 10. separates the right and left atria __________ 11. Located at the juncture of the superior vena cava and right atrium __________ 12. Supports the heart in the mediastinum __________ 13. Sits between the right ventricle and the pulmonary artery __________14. Distributes venous blood to the lungs __________15. Embedded in the right atrial wall near the tricuspid valve Column II a. Parietal pericardium b. Pulmonary artery c. Bicuspid Valve d. Pulmonic Valve e. Sinoatrial node f. Atrioventricular node g. Atrial Septumarrow_forwardChoose the letter of the correct answer. STATEMENT A B C D Arterial blood pressure is independent of Blood volume Heart rate Blood viscosity Influx of calcium ions Identify the TRUE statement(s). There may be several correct answers. An increased cardiac output is reflected in an elevated diastolic pressure. An increased cardiac output is reflected in a decreased diastolic pressure. An increase in the force of contraction produces an elevated systolic pressure. An increase in the force of ventricular contraction produces decreased diastolic pressure. In the absence of compensations, the stroke volume will decrease when Blood volume increases Venous return increases Contractility increases Arterial blood pressure increasesarrow_forward

It is a test that assesses the electrical activity of the heart through electrodes attached to the skin. The figure (A) on the X axis - represents the time and on the Y axis - the mV of an electrocardiogram. Image B represents the electrocardiogram of a rested adult patient. Based on the images, identify and comment on the diagnosis.arrow_forwardPlease do your own solution and dont copy paste from other posters answers.
