Algorithm Management of Left Ventricular Hypertrophy

Be able to describe the significance of ryanodine receptors found on the SR of cardiac contractile cells.

Given the role of potassium in myocardial cell action potentials, explain how hyperkalemia can stop the heart. Make sure to explain in terms of ion movements

Select TRUE or FALSE to best describe the statements below, relating the events of the cardiac cycle. Keep in mind that these events may be chemical, electrical and mechanical. atrial pressure is greater than ventricular pressure while semilunar valves are оpen ventricular pressure is greater than atrial pressure when the atrioventricular valves are closed atrioventricular valves are open during ventricular emptying the end diastolic volume of the ventricles is reached before ventricles contract 1 ventricular filling occurs before depolarization of the atria 1 atrioventricular valves and 1. TRUE 1 semilunar valves are closed at the beginning of ventricular systole 2. FALSE end systolic volume increases when more blood empties from the ventricles the greatest pressure is reached in the ventricles while they are emptying the right atrium depolarizes before the left atrium ventricular depolarization occurs during the T-wave semilunar valves are open during ventricular filling ventricular…
