WHAT MEDICATIONS WORK WITH CLASS II? WHAT ARE THEY USED TO PREVENT? |
|
Definition
BETA BLOCKERS. USED TO PREVENT AND TREAT SUPRAVENTRICULAR AND VENTRICULAR ARRHYTHMIAS |
|
|
Term
WHAT DOES CLASS II INHIBIT TO DECREASE AUTOMATICITY AND CONDUCTION VELOCITY. |
|
Definition
SYMPATHETIC EFFECTS. THIS DECREASES RATE OF RISE FOR SA NODE DEPOLARIZATION, DECREASE AV CONDUCTION AND INCREASE AV REFRACTORY PERIOD... LIKE DIG. |
|
|
Term
WHAT DOES CLASS II HAVE LESS EFFECT ON (HINT CONDUCTION) AND MORE EFFECT ON (HINT POTENTIALS)? |
|
Definition
LESS EFFECT ON VENTRICULA CONDUCTION AND MORE EFFECT ON NODAL POTENTIALS. |
|
|
Term
WHAT ARE THE 3 MOST COMMONLY USED BETA BLOCKERS FOR CLASS II? |
|
Definition
METOPROLOL, ESMOLOL, AND PROPANOLOL |
|
|
Term
WHAT IS ANOTHER BETA BLOCKER THAT CAN ACTUALLY WORK IN ANOTHER CLASS? |
|
Definition
SOTALOL. BLOCKS K CHANNELS ALSO SO IT IS ACTUALLY A CLASS II AND CLASS III. |
|
|
Term
WHAT IS A NON-SELECTIVE BETA BLOCKER THAT ALSO PROLONGS ACTION POTENTIAL DURATION AND WTI BY BLOCKING POTASSIUM CHANNELS (PHASE 3 PROLONGED). |
|
Definition
|
|
Term
SOTALOL IS USED FOR TREATMENT OF WHAT 2 ARRHYTHMIAS? |
|
Definition
VENTRICULAR AND ATRIAL ARRHYTHMIAS. |
|
|
Term
|
Definition
BLOCKS K CHANNELS THAT ARE RESPONSIBLE FOR REPOLARIZATION DURING STAGE 3. THIS CAUSES A LONGER PLATEAU DURATION. |
|
|
Term
IF CLASS III INCREASES THE REFRACTORY PERIOD WHAT DOES THAT DO TO REENTRY MECHANISMS? |
|
Definition
|
|
Term
CAN CLASS III CONTRIBUTE TO THE DEVELOPMENT OF AFTER DEPOLARIZATIONS? |
|
Definition
|
|
Term
TYPICALLY CLASS III DOESN'T SLOW VENTRICULAR CONDUCTION VELOCITY. WHAT MEDICATION IS AN EXCEPTION? |
|
Definition
|
|
Term
WHAT ARE 4 DRUGS THAT WORK ON CLASS 4? |
|
Definition
IBUTILIDE, DOFETILIDE, BRETYLIUM, AMIODARONE |
|
|
Term
WHAT TYPE OF ARRHYTHMIAS IS IBUTILIDE USED TO TERMINATE? |
|
Definition
|
|
Term
HOW DOES IBUTILIDE WORK LIKE OTHER CLASS III DRUGS? |
|
Definition
PROLONGS REPOLARIZATION BY INHIBITING K DURING PHASE 3. |
|
|
Term
WHAT KIND OF METABOLISM DOES IBUTILIDE HAVE? |
|
Definition
|
|
Term
WHAT IS THE HALF LIFE OF IBUTILIDE AND WHAT ARRHYTMIA CAN IT INDUCE? |
|
Definition
6 HRS. CAN INDUCE TORSADES |
|
|
Term
WHAT IS THE MAIN DIFFERENCE WITH DOFETILIDE? |
|
Definition
SIMILAR TO IBUTILIDE EXCEPT CAN BE GIVEN PO. |
|
|
Term
WHAT 2 THINGS IS BRETYLIUM USEFUL FOR? |
|
Definition
USEFUL AS AN ANTIHYPERTENSIVE AND ANTIARRHYTHMIC |
|
|
Term
WHAT TYPE OF ARRHYTHMIAS IS BRETYLIUM USEFUL FOR? |
|
Definition
VENTRICULAR ARRHYTHMIAS, BUT NO EFECT ON ATRIAL TISSUE. |
|
|
Term
|
Definition
INCREASES ACTION POTENTIAL DURATION IN NML AND ISCHEMIC CELLS. IT IS NO LONGER RECOMMENDED IN ACLS PROTOCOL. |
|
|
Term
WHAT ALL DOES AMIODARONE BLOCK? |
|
Definition
BLOCKS K, NA, AND CA CHANNELS ALONG WITH B RECEPTORS. IT DECREASES SA NODE AUTOMATOCITY, AV CONDUCTION VELOCITY AND PROLONGS AV NODE AND VENTRICULAR REFRACTORY PERIOD (BIG STOP SIGN FOR EVERYTHING CONDUCTION). |
|
|
Term
WHAT DOES AMIODARONE RESULT IN AN EKG? |
|
Definition
PROLONGS PRI, QRS, AND QTI |
|
|
Term
WHAT TYPE OF ARRHYTHMAIS CAN AMIODARONE BE USED TO TREAT? |
|
Definition
TREAT AND PREVENT RECEURRENCE OF ARIAL AND VENTRICULAR ARRHYTHMIAS |
|
|
Term
WHAT OTHER CLASS IS WITH AMIODARINE TO PREVENT ARRHYTHMIAS? |
|
Definition
|
|
Term
|
Definition
150MG OVER 10 MINUTES, THEN INFUSION OF 1MG/MIN FOR 6 HRS OR 300MG DILUTED IN 20ML NS RAPID IV FOR PULSELESS VT OR VF. UP TO 5MG/KG FOR INITIAL LOADING DOSE. |

WHAT IS THE HALG LIFE OF AMI? |
|
Definition
|
|
Term
WHAT ARE 7 SIDE EFFECTS OF AMI? REMEMBER IT IS MOSTLY R/T TISSUE ACCUMULATION. AMIO JUST SITS IN TISSUE FOR EVEN YEARS AFTER ADMINISTRATION. |
|
Definition
PULMONARY FIBROSIS (DON'T USE HIGH FIO2), BRADYCARDIA, DECREASE TN(SOME SAY D/T A-BLOCKADE, SOME SAY D/T IV MIXTURE), THYORID TOXICITRY (BLOCKS CONVERSION OF T4 TO T3), PERIPHERAL NEUROPATHIES, OCULAR DEPOSITS, CYANOTIC- LOOKING SKIN |
|
|
Term
WHAT 4 MEDICATIONS HAVE DRUG INTERACTIONS WITH AMI? |
|
Definition
B-BLOCKERS, CCB, DIG (PROLONGED CARDIAC EFFECTS AND INCREASE R/O DIG TOXICITY), OPIOIDS ESP. FENTANYL= COMBINED BRADYCARDIC EFFECT. |
|
|
Term
IS AMI HIGHLY PROTEIN BOUND? |
|
Definition
YES UP TO 96&%. THIS CAN LEAD TO OTHER DRUG INTERACTIONS. |
