CARDIOVASCULAR DISEASES Flashcards
The pulmonary artery is the only artery in the body that contains de-oxygenated blood

False
The ventricles have almost no blood supply during systole
True
The ‘lub’ in ‘lub-dub’ of the heart beat marks the beginning of diastole
False
The 12-lead ecg can pinpoint which coronary artery is involved in a myocardial infarct (heart attack)
True
The ‘QRS’ complex corresponds to diastole

statins - Monitor liver enzymes - Monitor for muscle pain- measure kinase- rhabdomyolysis- renal failure
Marfan syndrome is associated with:
lens dislocation
Diastolic blood pressure is
the pressure on the blood vessels when the ventricles are relaxing
Right heart failure a. can be caused by mitral valve prolapse b. can be secondary to lung disease c. causes pulmonary oedema d. can lead to left heart failure
can be secondary to lung disease
