Braunwald Question book Flashcards
Characteristic ECG findings of LAFB
- rS in inferior leads
- qR in anterolateral leads
- May have deep S waves in precordial leads
Marked increase of E/A ratio of mitral valve inflow velocity
Constrictive pericarditis
One French unit is equivalent to
0.33mm
What type of contrast to use in a patient with baseline renal insufficiency? What other benefit of this contrast?
Non-ionic low osmolar contrast agents. They also reduce the likelihood of adversity with anemic and electrophysiologic reactions during angiography
ECG changes of
1) hypocalcemia
2) hypercalcemia
3) hyperkalemia
4) hypokalemia
1) Long Isoelectric QT interval
2) J wave (Osborn wave) - also in hypothermia
3) narrow, peaked T wave Then a shortened QT interval. Then widened QRS. PR prolongation. Sine wave
4) flattened T wave, U wave prominence
Organize the following based on refractory period
- AV node
- His
- RBB
- LBB
RBB>LBB=AV node»His
What is the common morphology in Ashman beats
RBBB
What is the timing of an innocent murmur
Mid systolic
- a wave
- X descent
- c wave
- V wave
- y descent
- venous distention due to right atrial contraction
- atrial relaxation and downward to send of the base of the right atrium during RV systole
- ventricular contraction, is inconstant
- right atrial filling during the ventricular systole when the tricuspid valve is closed
- decline in right atrial pressure after the tricuspid valve opens
What is kussmaul’s sign
Paradoxical rise in the height of the venous pressure during inspiration. Reflect inability of the right side and chambers to accept additional volume
-constrictive pericarditis, right-sided heart failure, tricuspid stenosis
Conditions that make the a wave more prominent
- RV hypertrophy
- Pulm HTN
- tricuspid stenosis
