Q

Management if statin induced myalgias

A
  • CK
    • normal: hold, resume when asymptomatic, repeat CK in 6-12 weeks after restarting
      • >10x ULN: stop, Cr, urine myoglobin, consider rehydration, trend to normal
  • Consider changing to different stating/lowering dose depending on severity

Q

Amal Mattu’s ECG Approach to Pericarditis

A
  1. Is there any STD?
  2. Is there any convex/horizontal STE?
    3) Is STE III>II?

if YES, then AMI, if NO then

look for PR depression +-friction rub

look for checkmark sign (STEMI)

look for Spodick’s sign (downsloping TP, pericarditis)

Q

STEMI criteria

A

1) Use J-point, two contiguous leads
2) Men 3) Men >= 40: 2 mm in V2-V3 and 1 mm in all other leads
4) Women: 1.5 mm in V2-V3 and 1 mm in all other leads

V7-V9 use 0.5 mm cutoff except for men

Q

Wellen’s Syndrome

A

Biphasic or deeply inverted T-Waves in precordial +-lateral leads

Often in the absence/after resolution of symptoms

Sign of proximal LAD disease

17
Q

NSTEMI ACS Algorithm

19
Q

AHA FMC-to-balloon time for patients presenting to primary PCI centre

20
Q

AHA Door-in-to-door out time for STEMI at non-PCI hospital

21
Q

AHA TTT times for STEMI at non-PCI hospital

A

To primary PCI FMC-balloon = 120 minutes

If anticipated >120 minutes then lytic within 30 min

then

Transfer to PCI if failed reperfusion

or within 3-24h if successful

22
Q

RVH Criteria

A

RAD (90-180) + R>Q in V1 or S>R in V6

23
Q

LVH Criteria

A

Precordial:

S in V1 or V2 + R in V5 or V6 >35 mm

R in V5 >26 mm

R in V6 > 18 mm

R in V6 > R in V5

Limb:

R aVL > 13 mm

R aVF > 21 mm

R I > 14 mm

R I + S III > 25 mm

24
Q

LAFB

A

Can be normal

LAD

+

No QRS prolongation

+

qR I, aVL

rS II, III, aVF

25
Q

LPFB

A

Always abnormal

RAD

+

rS I, aVL

qR II, III, aVF

26
Bifascicular Block
RBBB + LAFB/LPFB
27
Trifascicular Block
RBBB + LAFB/LPFB + AV Block *or* LBBB + 1st deg AVB
28
Causes of prolonged QTc
hypo-K hypo-Ca hypo-Mg hypothermia Na Ch Blockers (TCA, Quinidine, antidepressants) MI IICP Congenital
29
ECG signs of TCA overdose
Tachycardia RAD R wave aVR \>= 3 mm IVCD
30
RBBB + LAFB + CP
* call cath lab * high chance LAD occlusion (Smith ECG blog)
31
When to worry about STEMI in RBBB
* V1, V2 should have some STD * isoelectric or STE is always abnormal * There shouldn't be STD/STE anywhere else * RBBB + LAFB (Dr. Smith's ECG blog) = cath
32
Approach to Narrow Complex, Regular Tachycardia
* **Sinus tach** * max is 220-age * **SVT** * **Aflutter with 2:1 conduction** * 150 +- 20 BPM * flip ECG upside down, check for sawtooth pattern (P-waves often inverted so hard to see on upright ECG) * Bix rule * if T wave is halfway between QRS complexes, look for a buried P wave in it, and the other buried P in the QRS complex
33
Bidirectional Vtach
QRS Axis changes 180 deg with each alternating beat Sign of severe digoxin toxicity Also sometimes in familial CPVT
34
Sustained vs. Non-sustained Vtach
* **sustained** * HR \>120/130 * lasts \>30s or HD unstable * shock or amio/procainamide * **non-sustained** * HR \>120/130 * \<30 s and stable * don't use antiarrhythmics * Mg if low * search for reversible causes * beta blockers OK
35
STEMI Activation Criteria
* STEMI * ischemic pain + ECG changes despite aggressive medical therapy (cath or transfer, no lytics) * ischemic CP + new acute heart failure * AMI + vtach (sustained or unsustained) * AMI + HD instability * Wellen's Syndrome * Diffuse ST depression + elevation in aVR * deWinter T waves * ROSC after Vfib/pulseless Vtach arrest * ROSC after some PEA arrests
