Procainamide 100-200 mg
Do not use digoxin, amiodarone, CCBs.
Options for pharmacologic cardioversion of atrial fibrillation?
-Ibutelide (4% risk of Torsades, avoid with HF)
-Amio (less effective)
-Procainamide (even less effective)
EKG findings of AVRT?
Delta-wave: slurred up-slope of QRS. AVRT=WPW.
Treatment of unstable SVT?
SYNCHRONIZED cardioversion. Biphasic, 120-200J.
Tx of unstable VT w/ a pulse?
-Regular -> DCCV, 100J
-Irregular -> Defib, 200J
Leukemia associated with bleeding and thrombosis (DIC or hyperfibrinolysis)
Treatment?
Acute Promyelocytic Leukemia
Rx: all trans retinoic acid
Worry about APL differentiation syndrome (Fever, leukocytosis, pulmonary infiltrates, and effusions) Rx: steroids
Leukemia associated with lymphadenopathy, organomegaly, CNS, bone pain, and tumor lysis
ALL
Leukemia associated with hypercalcemia and bone lesions
T Cell leukemia
3 classic symptoms of hyperviscosity syndrome
Mucosal bleeding
Neurologic symptoms
Visual symptoms (retinal artery plumping)
Treatment of Hypercalcemia
IV fluids, loop diuretics
Zolendronic acid or pamidronate
Calcitonin
Steroids
Medication used in tumor lysis syndrome if renal failure has developed
Rasburicase
Electrolytes abnormalities in tumor lysis syndrome
Hyperkalemia, Hyperuricemia, Hyperphosphtemia, Hypocalcemia
Common syndrome from CAR T therapy
Treatment?
Cytokine release syndrome (CRS)
Tocilizumab, Steroids
Must exclude as cause of hypterensive urgency / emergency?
-Medication effect (e.g., steroids)
-Toxic ingestion
-Hyperaldosteronism
-Cushing’s
-Pheochromocytoma
-Renal disease
Treatment of cyanide toxicity from nitroprusside?
IV Thiosulfate
BP targets with ACS & preferred agents?
SBP < 140 in first hour. Use nitroglycerine or BBs.
BP targets in aortic dissection? Agents to use?
SBP < 120 in first hour. Use esmolol, labetalol & nitroprusside.
Use of atropine cautioned in what three conditions?
-AMI, may increase infarct size
-Heart transplant. Lack of, or paradoxical, response.
-2nd degree type 2 block, or 3rd degree block. Block is below AV node, and will not be effective.
Medication used for CCB or BB overdose?
Glucagon
Pacer codes? (5 positions)
- Pacing
- Sensing
- Response
- Programability
- Multisite pacing
Pacer code: DDD.
What is it used for?
Used for all heart blocks. Maintains AV synchrony. Most physiologic mode. Must have wires in A & V.
What does magnet mode do for a pacer?
Turns off sensing, results in asynchronous pacing at fixed rate. I.e., AOO, VOO, DOO. (Pacing/Sensing/Response).
Can be useful to stop inappropriate pacing from electrical nose such as Bovie, or to stop PPM-induced tachycardia.
EKG findings in brugada syndrome? Treatment
ST elevations in V1, V2, no reciprocal changes in opposing leads. RBBB.
Rx Quinidine or amio, then ICD and ablation
Treatment of catastrophic antiphospholipid antibody syndrome?
Anticoagulation, steroids, plasma exchange.
Sx of cyanide exposure?
Tachycardia followed by bradycardia, hypotension, cyanosis, metabolic acidosis, and seizures
Indications for CT Surgery for TV IE? (4)
-Refractory bacteremia
-Vegetations >1cm
-HF
-Fungal BCx (+).
Sx of Steven-Johnson Syndrome / Toxic Epidermic Necrolysis?
Fever, malaise, myalgia, musous membrane involvement (photophobia, orodynia, odonyphagia). Prodrome of skin pain.
What is an AIVR (Accelerated Idioventricular Rhythm)?
Seen after cardiac reperfusion, wide-complex rhythm 50-120bpm. The reperfused Purkinje fibers beat faster than the SA node. Stable, no treatment needed.
Characteristic lab finding in TTP?
ADAMST13 level <10
False positives for the beta-D-glucan test for aspergillosis (7)?
HD with cellulose filters, PJP, Pseudomonas, Candida, augmentin, albumin, IVIG.
Bacterial infections implicated in Acute Hyperammonemia status post lung transplant?
Mycoplasma Hominis.
Ureaplasma Urealyticum & Parvum
Organophosphate pesticides cause what kind of poisoning?
Rx?
Cholinergic symptoms: Parasympathetic. Salivation, Lacrimation, Urination, Diarrhea, GI distress, Emesis. Also, bradycardia, and bronchorrhea. Like sarin nerve gas.
-Diazepam to prevent seizures.
-Atropine (high doses).
-Pralidoxime (Acetylcholinesterase reactivator)
New medication used for hyperkalemia?
Sodium zirconium cyclosilicate (Lokelma) is approved by the FDA for treatment of hyperkalemia in adults. It preferentially captures potassium in exchange for hydrogen and sodium, which reduces the free potassium concentration in the lumen of the GI tract and thereby lowers the serum potassium level.
