Indications for Digibind in Digoxin toxicity:
- All symptomatic bardycardias or life-threatening arrhythmias (VT, VF, Mobitz type 2, complete heart block)
- Hyperkalemia (>5 - 5.5 mEq/L)
- Evidence of end-organ dysfunction
Note: do not give calcium gluconate in patients with hyperkalemia due to digoxin toxicity as calcium increases the actions of digoxin.
#Cardiology
The most specific EKG finding in digoxin toxicity is atrial tachycardia with AV block
#Cardiology
A patient develops acute low back pain after coronary angiography. Exam reveals pain on hip flexion.
What is the diagnosis? What test will you perform to confirm?
#Cardiology
Atrial flutter ablation is usually more successful compared to atrial fibrillation. However, heart rate in atrial flutter is harder to control with medications than in atrial fibrillation.
#Cardiology
In a patient with STEMI undergoing PCI, the preferred antiplatlet drug is ticagrelor.
If the patient undergoes thrombolysis, the preferred drug is clopidogrel.
#Cardiology
Indicators of successful thrombolysis in STEMI are:
Resolution of chest pain, normalization of ST-segment, and development of transient benign accelerated idioventricular rhythm (reperfusion arrhythmia)
#Cardiology
TIMI score is used to estimate mortality risk in patients with Unstable Angina or NSTEMI.
Scores from 0-2 are low risk, 3-5 are intermediate risk, and scores 6-7 are high risk.
Patients with intermediate to high-risk should undergo angiography within 24-48 hours. Low-risk patients should undergo cardiac stress testing before discharge.
#Cardiology
Conditions in which EKG cannot be interperated on cardiac stress testing or during evaluation of ACS include:
-LBBB
- Use of certain cardiac drugs such as digoxin and procainamide (cause ST-T wave depression)
- Wolff-Parkinson-White syndrome
- Ventricular pacing
- Left ventricular hypertrophy with significant ST-T wave abnormalities
#Cardiology
High risk features on cardiac stress testing include:
- Early onset chest pain or ST wave changes
- large areas of ischemia
- hemodynamic instability
#Cardiology
If stable angina symptoms persist on optimal medical management or there are high-risk features on the cardiac stress test, perform coronary angiogram.
#Cardiology
The target resting heart rate in stable angina is 55-60 bpm.
Treatment is β-blocker and/or Non-dihydropyrodine CCB.
If not angina controlled, use long-acting nitrates.
If still not controlled, use ranolazine.
#Cardiology
Prophylaxis for Rheumatic fever is with IM penicillin G (every 4 weeks), Penicillin V (daily), or Azithromycin (daily)
Duration depends on severity of disease:
~ Uncomplicated RF: until 21 yrs old OR for 5 yrs
~ Carditis without valvular disease: 21 yrs old OR for 10 yrs
~ Carditis with valvular disease: 40 yrs old OR for 10 yrs
Whichever is longer

Indications to admit a patient with gross hematuria:
- Hypotension
- Anemia or thrombocytopenia
- Anticoagulation intake
- Very old
- Failure of irrigation to yield clear urine

#Clinical
Kramer's scale can be used to estimate total bilirubin levels of an infant with jaundice if bilirubin measurement can't be obtained.
#Pediatrics
Behcet disease is the only systemic vasculitis known to cause pulmonary artery aneurysms.
Takayasu arteritis can cause aortic aneurysms.
Kawasaki disease can cause coronary aneurysms.
