quiz 1 Flashcards
which cell adaptaion is primarily responsible for increased myocardial mass in a postnatal animal
Dr Bender
hypertrophy
cardiac tamponade is a life-treatening condition characterized by imparied cardiac filling due to:
Dr Bender
heart compression due to increased pressure in pericardial cavity (rapid fluid accumulation)
what is the typical order of events for the development of life-sided congestive heart failure in a dog?
Dr Quilty
- aorta - aortic valve - LV - mitral valve doesnt work - LA - PV - pulmonary capillaries - fluid leaks into interstitium - pulmonary edema
- most common: DMVD (blood flows backward from LV to LA during systole, as pressure & volume increases in LA, blood goes into PV)
what is preload
Dr Oyama
- the stretch of the ventricle just before the onset of contraction (end diastolic volume)
- achieving an optimal stretch of myocyte causes improved contractility)
what is the most appropriate combination of drugs for chronic oral trearment of dogs with CHF
Dr Oyama
FAPS - furosemide, ACEI, pimobendan, spironolactone
what is the most appropriate chronic oral treamtment in dogs with Stage B1 myxomatous mitral valve disease (MMVD)
Dr Oyama
none
how is pulmonary hypertension diagnosed non-invasively
Dr Crooks
echocardiogram
which ECG waveform or interval (labeled with a number) is CORRECTLY matched with the corresponding electrical event?
DR crooks
- 1 = p wave - atrial depolarization
- 2 = PR interval - conduction through the AV node
- 3 = QRS complex - ventricular depolarixation
- 4 = T wave - ventricular repolarization
A 7 year old Doberman Pinscher with a history of dilated cardiomyopathy (DCM) presents to the Emergency Service for evaluation of coughing. On physical examination, the heart rate is 240 bpm and the rhythm is irregularly irregular. ECG shows absent P waves and normal (narrow, upright) QRS complexes. What is the most likely rhythm diagnosis?
Dr crooks
atrial fibrillation
A 13 week old German Shepherd puppy comes to your practice for puppy vaccines. You auscult a grade 5/6 continuous heart murmur loudest at the left heart base. Femoral pulses are bounding. Your top differential diagnosis is:
DR Kraus
PDA
What is the best treatment for a dog with class B2 chronic valve disease?
Dr Kraus
pimobendan
You are evaluating a 2 year old MC Coonhound recently rescued from Louisiana. The owner reports coughing and exercise intolerance. The chest radiographs show dilated and tortuous pulmonary arteries. Which of the following diagnostic tests is your top priority?
Dr kraus
heartworm antigen tests
You evaluate a 12 year old female spayed Chihuahua. On physical examination, a grade IV/VI left apical systolic heart murmur is detected. Which of the following is the most likely cause of the murmur?
Dr kraus
MMVD
A cat presents to your clinic in severe respiratory distress. It is a fractious cat and you will only have time to evaluate one view via TFAST. Which view would you strive to acquire?
dr kraus
right parasternal long axis view
Fill in the blanks of the statements regarding large animal cardiac disease
dr navas
- aortic regurgitation
- mitral regurgitation
- tricuspid regurgitation
- bounding peripheral pulse (not grade)
which of the following descriptions of the QRS under the arrow is correct
Dr gelzer
ventricular premature contraction
