What is left ventricular perfusion?
Left Ventricular dysfunction-A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
What conditions are contraindicated for myocardial resection?
right heart failure, elevated left ventricular enddiastolic pressures, and pulmonary hypertension (high blood pressure in the circulation around the lungs).
What is normal perfusion?
Well pulse pressure is systolic (top) minus diastolic (bottom). So the value you get should be between 30-49 to be normal.
What is the difference between Left Ventricular Hypertrophy and Left Ventricular Dysfunction?
LVH (Left Ventricular Hypertrophy) is (anatomical) structural condition and status of the heart, while Left Ventricular Dysfunction is disturbance in physiological functions and status of heart.
What does QRS wave represent in a EKG?
P wave represent the electrical impulse across the right and left atrium. It travels across the atrial wall. Qrs complex indicates the electrical impulse through the myocardial ventricles. It travels through the bundle of HIS (GOD), right and left bundle branches and then across the right and left ventricular walls.
Will the apical beat be shifted in left ventricular hypertrophy?
Yes, left ventricular hypertrophy will shift the apical beat.
What are the compensatory mechanisms the overloaded heart resorts to when attempting to maintain normal cardiac output?
--Sympathetic nervous system stimulation (inc. catecholemines) --RAAS activation --Myocardial hypertrophy --Increased CO, with a rise in left ventricular end-diastolic pressure
If a myocardial infarction damaged the left bundle branch how would this affect the spread of the action potential?
Ventricular depolarization takes longer because impulses in the left ventricle must travel from cell to cell rather than traveling down the left bundle branch and Purkinje fibers. (This will lead to a longer QRS complex on an ECG)
What is a Left Ventricular Assist Device called?
LVAD
When was the left ventricular assist device invented?
1982
What are the risks of a misfire of the left ventricle?
The risk of left ventricular misfire is a left ventricular free wall rupture. A misfire in either the right or the left ventricle of the heart is an electrical problem with the circuitry. These conditions are usually treated through angioplasty.
What does the medical abbreviation LVF mean?
Left Ventricular Failure
