|
What is the relation between calcium and QT length?
|
inverse relation
|
|
|
What medications might be given for long QT?
|
antihistamines like cetirizine
magnesium (2g bolus, then 2-4 mg/min) isoproterenol |
|
|
What effect does digoxin on PR and QT?
|
lengthens PR
shortens QT |
|
|
A long QT patient has a heart rate > 150. What is treatment?
|
cardiovert the patient if HR is > 150, or pt is unstable
--then, Mg 2g followed by 2-4mg/min --transvenous pacing --isoproterenol |
|
|
What is the effect of quinidine on QT?
|
lengthens
|
|
|
A pt has cirrhosis which is causing portal HTN. What is first line treatment?
|
amlodipine for portal HTN
spironolactone if HTN leads to hyperaldosteronism. |
|
|
What are the first line meds for diastolic heart failure?
|
ACEI, then BB and CCB
no diuretics! |
|
|
What are the first line meds for systolic heart failure?
|
ACEI, diuretics
no CCBS except amlodipine |
|
|
First line HTN tx for pt with COPD
|
ACEI
no BB (bronchospasm) |
|
|
What is the med tx for Prinzmetal's angina?
|
CCBs (verapamil, diltiazemA)
|
|
|
Mnemonic:
Piss for SYStolic. Meaning? |
Diuretics are used for systolic heart failure but not diastolic.
The other main med for systolic HF is ACEIs. |
|
|
A pt has COPD and hypertension. What hypertension meds should be prescribed? Avoided?
|
ACEIs first; avoid BBs because of bronchospasm.
|
|
|
Standing make the murmur of AS and MR [earlier, later].
|
earlier
Standing reduces preload |
|
|
Standing make the murmur of AS and MR [louder, softer].
|
softer
|
|
|
Valsalva makes the murmur of AS and MR [earlier, later].
|
earlier
Valsalva reduces preload |
|
|
Squatting makes AS and MR [ealier, later].
|
later
Squatting increases both preload and afterload, tensing chordae and making click delayed. |
|
|
Squatting makes MVP [louder, softer].
|
MVP volume is not affected, but squatting does make mumur later.
|
|
|
Squatting makes murmur of HCM [earlier, later].
|
earlier (opposite of others)
|
|
|
